The second sealing part 21 is disposed on the outer periphery of the top cover 23.
[0052] The filter element 3 includes a filter screen 31 and a pressing component 32. The middle part of the filter screen 31 is movably sleeved on the middle part of the pressing component 32. The filter screen 31 is upside down on the annular support part 14. The bottom end of the pressing component 32 is connected to the spring-loaded sealing component 2, and the top end forms a pressing head 321. The spring-loaded sealing component 2 forms a pressing and springing action by pressing the pressing component 32.
[0053] In one embodiment, the top edge of the annular support 14 is provided with a protruding ring 141. The inner diameter of the protruding ring 141 is equal to the outer diameter of the filter screen 31. The filter screen 31 is upside down inside the protruding ring 141 to prevent the filter screen 31 from shaking. Alternatively, it can also hold the outer edge of the filter screen 31 in place to improve the stability of the filter screen 31 during use.
[0054] Alternatively, in another embodiment, to further improve the drainage effect, the outer ring of the filter screen 31 is provided with a filter ring 311. The top of the filter ring 311 is provided with spaced-apart baffles 3111, and the bottom is provided with spaced-apart supports 3112. A water passage gap 3113 is formed between the filter ring 3111 and the annular support portion 14 through the support 3112, which also has drainage and filtration functions. In addition, the filter ring covers the outer periphery of the annular support portion 14, which can improve the stability and firmness of the filter screen 31 during use.
[0055] In one embodiment, the bottom end of the pressing component 32 is fitted onto the outer periphery of the top end of the spring-loaded seal 2, which further improves the installation stability and firmness of the filter element 3. Additionally, to prevent the filter screen 31 from detaching from the pressing component 32, the pressing component 32 includes a pressing body and a pressing head 321. The bottom of the pressing body is connected to the spring-loaded seal 2, and a limiting ring 322 protruding outwards is provided at the bottom. The filter screen 31 is fitted onto the outer periphery of the pressing body, and the pressing head 321 is mounted on the top end of the pressing body. The filter screen 31 is constrained on the pressing component 32 by the pressing head 321 and the limiting ring 322.
[0056] Based on the above embodiments, the main body of the filter screen 31 is in the shape of an inverted bowl, and the edges of the filter screen 31 are bent and expanded outward, thereby forming a larger water passage area and filtration area, and making it less prone to clogging.
[0057] During installation, the drain seat 1 is installed inside the drain hole of the water tank, the first sealing part 13 blocks the drain hole, and the annular support part 14 is attached to the bottom of the water tank. Then, the spring-loaded seal 2 and the filter element 3 are installed on the drain seat 1. In use, the state of the spring-loaded seal 2 is switched by pressing the filter element 3, while the filter screen 31 remains upside down on the annular support part 14 to filter the drainage. When it is necessary to clean the debris entangled on the filter screen 31, simply remove the filter element 3 for cleaning.
[0058] The drain device provided by this utility model adopts an inverted filter screen 31. When used with a water tank, the filter screen 31 protrudes from the bottom of the water tank, which makes it less likely for the filter screen 31 to become full of garbage, thereby improving the drainage efficiency of the water tank.
