The cover 2 is provided with a first sealing element 3 corresponding to the inner liner 5, and a second sealing element 4 corresponding to the annular protrusion 11. When the cover 2 is placed on the main body 1, the inner side of the bottom of the cover 2 is sealed with the inner liner 5 through the first sealing element 3, and the outer side of the bottom of the cover 2 is sealed with the annular protrusion 11 through the second sealing element 4.

[0036] like Figures 3-8 As shown, the first sealing element 3 is disc-shaped, and the edge of the first sealing element 3 is provided with annular positioning parts 31 vertically on both the upper and lower sides. The cover body 2 is provided with annular grooves 21 corresponding to the annular positioning parts 31. The first sealing element 3 is engaged with the annular grooves 21 through the annular positioning parts 31 on one side, and the annular positioning parts 31 on the other side of the first sealing element 3 is inserted and sealed with the inner liner 5, so that the first sealing element 3 can be detachably installed at the bottom of the cover body 2. At the same time, the downward annular positioning parts 31 of the first sealing element 3 are inserted and engaged with the inner cavity of the inner liner 5 to achieve sealing, thereby improving the sealing performance between the first sealing element 3 and the inner liner 5. The outer wall of the annular positioning parts 31 is provided with guide slopes 311. The annular positioning parts 31 on both sides are guided and inserted into the corresponding inner liner 5 and annular grooves 21 through the guide slopes 311. The addition of guide slopes 311 improves the ease of insertion of the annular positioning parts 31 with the inner liner 5 and annular grooves 21.

[0037] like Figures 3-4 and Figures 6-8 As shown, the second sealing element 4 is a sealing ring, which is installed on the bottom of the cover 2 corresponding to the annular protrusion 11. The upper end surface of the annular protrusion 11 is a flat surface 111, and the bottom of the sealing ring contacts and seals with the upper end flat surface 111 of the annular protrusion 11. The bottom of the cover 2 has an installation groove 22 for installing the sealing ring, and the side wall of the sealing ring is integrally provided with a snap-fit ​​part 41. The cover 2 has a snap-fit ​​groove 23 corresponding to the snap-fit ​​part 41. The sealing ring is engaged with the snap-fit ​​part 41 and the corresponding snap-fit ​​groove 23, so that the sealing ring can be detachably installed on the bottom of the cover 2, which facilitates the installation, removal and cleaning of the sealing ring. A handle 51 is hinged to the outer wall of the inner liner 5. The middle part of the handle 51 is bent outward to form an extraction part 511.
