In this implementation plan, the storage box is opened by using the slot 5 on one side of the box cover 4 to pry and remove the box cover 4 with your fingers, revealing the internal space of the storage box 3. Multiple partitions 13 inside the storage box 3 divide the space into independent areas, which can be classified and stored according to the type of wet items. Categorize wet items: Place wet clothes, wet towels, swimsuits and other wet items into different areas separated by the divider 13 to avoid different wet items from contaminating each other. After placing them, insert the lid 4 into the slot on one side of the storage box 3. The silicone pad 14 inside the slot will fit tightly against the connection between the lid 4 and the storage box 3, which can increase friction to prevent the lid 4 from accidentally falling off, and also play a certain sealing role to reduce moisture leakage. Automatic moisture diversion: Water dripping from wet items will seep down through the mesh plate 12 and flow to the bottom of the storage box 3. Then, it will enter the one-way drain valve 21 through the bottom hole. Due to the one-way flow characteristic of the one-way drain valve 21, the water can only flow smoothly into the water tank 6 below, and there will be no backflow of sewage in the water tank 6 into the storage box 3, which effectively ensures that the wet items in the storage box 3 are stored in a relatively dry environment. To achieve the limiting purpose, this device employs the following technical solution: A limiting component is provided on one side of the housing 1. The limiting component includes an inner groove 10, which is formed inside the housing 1. A locking block 15 is provided inside the inner groove 10, and the locking block 15 engages with the limiting groove 20. A toothed plate 17 is fixedly provided inside the locking block 15. Multiple springs 16 are fixed between the locking block 15 and the side wall of the inner groove 10. A knob 8 is provided on one side of the housing 1, and a rotating rod 18 is fixedly provided on one side of the knob 8. One end of the rotating rod 18 extends into the inner groove 10 and is connected to the side wall of the inner groove 10 via a bearing. The rotating rod 18 is externally fixed with a gear 19, which meshes with the toothed plate 17. The locking block 15 slides inside the inner groove 10. The cleaned water tank 6 is aligned with the water tank groove 9 and inserted to ensure that the fixing ring 22 on one side of the water tank 6 is in close contact with the sealing ring 23 in the groove of the water tank groove 9. The sealing ring 23 can enhance the sealing between the water tank 6 and the water tank groove 9 and prevent water leakage after the water tank 6 is installed. Then, the knob 8 is released, and the compressed spring 16 is reset under the action of elastic force, pushing the locking block 15 to re-lock into the limiting groove 20 of the water tank 6, completing the fixed installation of the water tank. At this time, the knob 8 also turns back to the initial position. In order to achieve the purpose of drainage, the device adopts the following technical solution: a plug 7 is threadedly connected to one side of the water tank 6. The plug 7 can be rotated to open, so as to facilitate the drainage of water inside the water tank 6. In order to facilitate movement, the device adopts the following technical solution: a moving wheel 2 is installed on one side of the box body 1, which facilitates the movement of the suitcase; In order to facilitate dragging, the device adopts the following technical solution: another box 1 is provided with a pull rod on one side, which makes it easy to drag the suitcase.
[0020] The usage process of this utility model is as follows: Open the storage box: Use your fingers to pry open and remove the box lid 4 through the slot 5 on one side of the lid 4 to reveal the internal space of the storage box 3. Multiple partitions 13 inside the storage box 3 divide the space into independent areas, which can be classified and stored according to the type of wet items. Categorize wet items: Place wet clothes, wet towels, swimsuits and other wet items into different areas separated by the divider 13 to avoid different wet items from contaminating each other. After placing them, insert the lid 4 into the slot on one side of the storage box 3. The silicone pad 14 inside the slot will fit tightly against the connection between the lid 4 and the storage box 3, which can increase friction to prevent the lid 4 from accidentally falling off, and also play a certain sealing role to reduce moisture leakage. Automatic moisture diversion: Water dripping from wet items will seep down through the mesh plate 12 and flow to the bottom of the storage box 3. Then, it will enter the one-way drain valve 21 through the bottom hole. Due to the one-way flow characteristic of the one-way drain valve 21, the water can only flow smoothly into the water tank 6 below, and there will be no backflow of sewage in the water tank 6 into the storage box 3, which effectively ensures that the wet items in the storage box 3 are stored in a relatively dry environment. Unlocking the water tank: When the water in the water tank 6 accumulates to a certain level and needs to be cleaned, rotate the knob 8 on one side of the tank body 1. The rotation of the knob 8 drives the rotating rod 18, which is fixedly connected to it, to rotate synchronously. The rotating rod 18 rotates stably on the side wall of the inner groove 10 of the tank body 1 through the bearing, and the gear 19 fixedly sleeved on its outside rotates together. Since the gear 19 meshes with the toothed plate 17 inside the locking block 15, the rotation of the gear 19 will be converted into the horizontal movement of the toothed plate 17, which will then drive the locking block 15 to slide away from the water tank 6 in the inner groove 10. At this time, the spring 16 between the locking block 15 and the side wall of the inner groove 10 is compressed, and the locking block 15 disengages from the limiting groove 20 on one side of the water tank 6, releasing the limiting fixation of the water tank 6. Remove and empty the water tank: Remove the water tank 6 from the water tank 9, unscrew the plug 7 on one side of the water tank 6, pour the sewage collected in the water tank into the sewer or designated drainage point, after emptying, you can simply rinse and clean the inside of the water tank 6, and then tighten the plug 7 again. Reinstall the water tank: Align the cleaned water tank 6 with the water tank groove 9 and insert it, ensuring that the fixing ring 22 on one side of the water tank 6 is in close contact with the sealing ring 23 in the groove of the water tank groove 9. The sealing ring 23 can enhance the sealing between the water tank 6 and the water tank groove 9, preventing water leakage after the water tank 6 is installed. Then, loosen the knob 8, and the compressed spring 16 will reset under the action of elastic force, pushing the locking block 15 to re-lock into the limiting groove 20 of the water tank 6, completing the fixed installation of the water tank. At this time, the knob 8 will also turn back to the initial position.
