[0025] Reference Figure 1 The existing drain valve 100 uses an aluminum cylinder 170 with filter holes 171 to drain water accumulated inside the container. According to TIR (Transport International Routier) requirements, the diameter of the drainage holes inside the refrigerated container drain valve 100 must not exceed 3mm. Therefore, the drain valve 100 of existing containers (especially refrigerated containers) is prone to clogging. Clogging prevents timely drainage of water, which can damage the cargo inside the container. Furthermore, workers are prone to damaging the drain valve 100 during the cleaning process when clogging occurs, thus increasing the container's maintenance costs.

[0026] Therefore, referring to Figure 2 and Figure 3 This utility model provides a drain device 100 for use in a container. The container includes a floor, and the drain device 100 includes an installation cylinder 110 and an inner core 120.

[0027] The mounting cylinder 110 is a cylindrical structure with a top opening 111 and a bottom opening 112 at both ends. The mounting cylinder 110 is used to be installed through the floor. The top opening 111 is used to connect to the top surface of the floor, and the bottom opening 112 is used to drain accumulated water.

[0028] The inner core 120 is inserted into the mounting cylinder 110. The inner core 120 includes a central shaft 121 and a helical blade 122. The helical blade 122 is connected to the periphery of the central shaft 121 and extends helically along the axial direction D2 of the central shaft 121. The helical blade 122 and the inner wall of the mounting cylinder 110 form a drainage channel 123 that extends helically around the axis of the central shaft 121. The two ends of the drainage channel 123 are respectively connected to the top opening 111 and the bottom opening 112.

[0029] According to the present invention, the inner core 120 of the drain device 100 is inserted into the mounting cylinder 110, such that the inner core 120 and the mounting cylinder 110 form a drainage channel 123 that extends spirally around the central axis 121. The drainage channel 123 allows water entering the mounting cylinder 110 to be discharged. Compared with the traditional drain device 100 with limited aperture filter holes 171, it is less prone to clogging and has higher drainage efficiency. Furthermore, when cleaning the drain device 100, the inner core 120 can be removed from the mounting cylinder 110 for cleaning, which helps prevent damage to the drain device 100 and thus reduces maintenance costs.

[0030] This utility model also provides a container, including a floor and a drain device 100 as described above, the drain device 100 being disposed on the floor. The container according to this utility model has a drain device 100 that is not easily clogged and has high drainage efficiency, which helps prevent damage to goods inside the container due to water accumulation inside.

[0031] Optionally, the floor includes an upper floor, an insulation layer, and a lower floor, with the insulation layer disposed between the upper and lower floor. The floor has mounting holes that pass through the upper floor, the insulation layer, and the lower floor. The mounting cylinder 110 of the drain device 100 passes through the mounting holes, and the top opening 111 of the mounting cylinder 110 is flared and connected to the upper floor, thereby enabling the drain device 100 to be installed on the container. The structure is stable and the drainage efficiency is high.

[0032] Optionally, the upper floor can be made of aluminum, and the mounting cylinder 110 can also be made of aluminum, which facilitates the welding of the top opening 111 of the mounting cylinder 110 to the upper floor, resulting in a stable connection and good sealing.

[0033] Optionally, the mounting cylinder 110 and the upper floor can also be connected together with fasteners and a seal, which facilitates disassembly and assembly and provides good sealing.

[0034] Alternatively, the container can be a refrigerated container or other container that requires the drainage of water inside.

[0035] Optionally, the drainers 100 are installed at the four corners of the container to effectively drain water from all parts of the container, thus preventing water from accumulating inside the container and damaging the goods.

[0036] Optionally, refer to Figure 2 and Figure 3 The drain device 100 also includes a connecting member 130, which includes a cylindrical wall 131 and a flange 132. The flange 132 is connected to the outer side of the cylindrical wall 131 and protrudes from the outer side of the cylindrical wall 131 in a circumferential direction D1. The flange 132 is used to connect to the bottom surface of the lower floor and is provided with a connecting hole 133, so that the connecting member 130 can be fixed to the lower floor by fasteners. The cylindrical wall 131 is fitted onto the bottom end of the mounting cylinder 110, and the bottom opening 112 extends into the cylindrical wall 131. Therefore, the connection member 130 fixes the bottom end of the mounting cylinder 110, making the mounting cylinder 110 more stable. This makes it less likely for the top opening 111 of the mounting cylinder 110 and the upper floor to crack, which is beneficial to the sealing and stability of the drain device 100 during long-term use.

[0037] Optionally, the drain device 100 also includes a water outlet 140, which is snapped to the cylinder wall 131 by a snap-fit ​​connector 150, making it easy to disassemble and clean the water outlet 140.

[0038] Reference Figure 2 and Figure 3 The inner wall of the water outlet 140 is provided with a protrusion 141, and the outer side of the cylindrical wall 131 of the connecting member 130 is provided with a snap-fit ​​groove 134. The water outlet 140 is sleeved on the lower end of the cylindrical wall 131, so that the protrusion 141 is embedded in the snap-fit ​​groove 134, thereby making the water outlet 140 firmly connected to the bottom of the connecting member 130, for discharging water discharged from the bottom opening 112 of the mounting cylinder 110 and the cylindrical wall 131. The snap-fit ​​member 150 can be a snap spring, which is sleeved on the outer side of the water outlet 140, thereby further securing the connection between the water outlet 140 and the cylindrical wall 131.

[0039] Optionally, the water outlet 140 can be a duckbill type. When the water pressure in the water outlet 140 is sufficient, the accumulated water can be discharged. The duckbill type water outlet 140 can prevent external media from entering the water outlet 140 or even the container, which helps to ensure the container's sealing and insulation performance.

[0040] Optionally, the drain device 100 also includes a plug 160, which is removably inserted into the top opening 111 so that the installation cylinder 110 can be sealed when the drain device 100 is not in operation, which helps to ensure the sealing and insulation performance of the container, and also prevents impurities and dust from entering the installation cylinder 110 and blocking the drainage channel 123.

[0041] Reference Figure 2 and Figure 3 When in use, the central axis AX of the drain device 100 is parallel to the height direction of the container, that is, the drain device 100 is placed vertically.

[0042] Optionally, refer to Figure 2 The diameter d5 of the central shaft 121 is 3 mm to 10 mm. While ensuring the structural strength of the inner core 120, the central shaft 121 does not excessively encroach on the space of the drainage channel 123, thus ensuring the drainage efficiency of the drain device 100. Optionally, the outer diameter d2 of the spiral blade 122 is 30 mm to 80 mm. This ensures that the spiral blade 122 has a sufficient outer diameter, allowing the drainage channel 123 to have a sufficient cross-sectional area for water passage and reducing the clogging of the drainage channel 123 by impurities.

[0043] Optionally, the pitch d4 of the spiral blade 122 is 3 mm to 20 mm, thereby ensuring that the drainage channel 123 has a sufficient cross-sectional area for passing water, which can both accelerate the drainage efficiency of the drain device 100 and reduce the blockage of the drainage channel 123 by impurities.

[0044] Optionally, the thickness d3 of the spiral blade 122 is 1 mm to 4 mm, so that the thickness d3 of the spiral blade 122 will not occupy too much space of the drainage channel 123, thereby ensuring the drainage efficiency of the drain device 100.

[0045] Optionally, the inner core 120 can be constructed from one of aluminum, PVC, ABS, or PE, resulting in lightweight, robust structure, and low manufacturing cost. Furthermore, the central shaft 121 and the helical blades 122 are integrally molded, facilitating manufacturing and providing high structural strength.

[0046] Optionally, the height h1 of the mounting cylinder 110 is 50 mm to 100 mm, and the height h2 of the inner core 120 is 40 mm to 90 mm, so that the inner core 120 can be housed in the mounting cylinder 110, which provides good protection for the inner core 120.

[0047] Optionally, the inner diameter d1 of the mounting cylinder 110 is 30 mm to 80 mm, and the inner diameter d1 of the mounting cylinder 110 is consistent with the outer diameter d2 of the spiral blade 122, so that water is not easy to leak between the spiral blade 122 and the inner wall of the mounting cylinder 110, thereby making the inner core 120 have a good guiding effect on the water.

[0048] Optionally, the plug 160 is made of rubber, and the height h3 of the plug 160 is 10 mm to 30 mm, so that the plug 160 can seal and fit into the top opening 111 of the mounting cylinder 110.
