[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] See Figures 1-5 The drainage structure of this water tank includes a water tank body 1, which has a liquid storage chamber 11. The lower side of the water tank body 1 is provided with a downwardly extending connecting part 12. The inner side of the connecting part 12 is hollow and forms a drainage chamber 121. The bottom of the connecting part 12 is provided with an upper drainage hole 122. The outer side of the connecting part 12 is connected to a lower water shell 2. The lower water shell 2 is provided with a lower drainage hole 21. The upper drainage hole 122 and the lower drainage hole 21 are connected to the drainage chamber 121 in sequence. A locking member 3 is connected between the lower water shell 2 and the connecting part 12. The locking member 3 can generate tension on the lower water shell 2 and the connecting part 12 respectively to fix the lower water shell 2 to the water tank body 1. By setting the locking member 3, the lower water shell 2 does not need to rotate relative to the water tank body 1 as a whole, which simplifies the installation difficulty of the lower water shell 2 and the water tank body 1.

[0026] Furthermore, the upper side of the locking member 3 is provided with a limiting part 31, which abuts against the bottom inner side of the connecting part 12. The lower section of the locking member 3 extends downward through the connecting part 12 and is connected and engaged with the lower water shell 2 through a threaded structure. The locking member 3 can pull the lower water shell 2 to be installed and fixed to the water tank body 1 when rotated in the forward direction. The locking member 3 can be separated from the lower water shell 2 and the lower water shell 2 from the water tank body 1 when rotated in the reverse direction. When installing or removing the lower water shell 2, it is only necessary to drive the locking member 3 to rotate through the limiting part 31 above the water tank body 1. The operation is relatively simple and convenient.

[0027] Furthermore, the locking member 3 passes through the bottom center of the connecting part 12, and the bottom center of the lower water shell 2 is provided with a stud part 22. Several connecting ribs 23 are provided between the stud part 22 and the main body of the lower water shell 2. A lower drain hole 21 is formed between adjacent connecting ribs 23. The structure of the connection between the lower water shell 2 and the locking member 3 is relatively simple, and the through hole formed between the stud part 22 and the connecting ribs 23 can be used as the lower drain hole 21, further simplifying the overall structure.

[0028] Furthermore, the limiting part 31 is connected to a lock key 4 that can be detached from it. The lock key 4 can drive the locking member 3 to rotate in the forward or reverse direction through the limiting part 31. The lock key 4 can be used as a tool to rotate the locking member 3 in cooperation with the limiting part 31, further simplifying the difficulty for the user to operate the locking member 3 to rotate.

[0029] Furthermore, the limiting part 31 is in the shape of a ring, and the upper side of the limiting part 31 is provided with a number of limiting recesses 311. The lock key 4 can be fitted onto the outside of the limiting part 31. The lock key 4 is provided with a limiting rib 41 corresponding to the limiting recesses 311. The limiting rib 41 and the limiting recesses 311 are connected and cooperate to enable the lock key 4 to drive the limiting part 31 to rotate. The cooperation between the limiting rib and the limiting recesses 311 can improve the fit between the lock key 4 and the limiting part 31, making it easier for the lock key 4 to drive the locking member 3 to rotate through the limiting part 31.

[0030] Furthermore, a movable push rod 5 is provided inside the liquid storage chamber 11. The movable push rod 5 is linked to a sealing element 6. The movable push rod 5 can drive the sealing element 6 to open or close the upper drain hole 122. The user can control the movable push rod 5 above the liquid storage chamber 11 to make the sealing element 6 open or close the upper drain hole 122, thereby enabling the water storage chamber to drain water or maintain water storage.

[0031] Furthermore, a linkage block 7 is provided between the movable push rod 5 and the seal 6. The seal 6 and the linkage block 7 are installed and fixed, and the linkage block 7 is connected and cooperates with the movable push rod 5.

[0032] Furthermore, the linkage block 7 is connected to a spring switch 8. The movable push rod 5 can continuously press the spring switch 8 through the linkage block 7, causing the linkage block 7 to switch the sealing element 6 between the open state of the upper drain hole 122 and the closed state of the upper drain hole 122.

[0033] Users can quickly control the opening or closing of the upper drain hole 122 by simply pressing the seal 6.

[0034] The spring switch 8 is a device that can achieve positioning and keep the elastic reset element deformed when pressed for the first time, and achieve reset of the elastic reset element when pressed for the second time. The specific structure of this spring switch 8 belongs to the prior art and is widely used in the field, which can be understood by those skilled in the art.

[0035] Furthermore, a separable water-isolating component 9 is connected inside the liquid storage chamber 11. Several filter holes 91 are distributed on the water-isolating component 9. The movable push rod 5 passes through the water-isolating component 9. The movable push rod 5 and the water-isolating component 9 are movably connected by a sealing ring 10. The water-isolating component 9 can isolate the residue from the water, allowing the residue to accumulate on the water-isolating component 9 for easy handling by the user.

[0036] Furthermore, the main body 1 of the water tank is provided with a limiting groove 13 corresponding to the water-separating component 9. The water-separating component 9 is embedded in the limiting groove 13, which facilitates the installation and positioning between the water-separating component 9 and the main body 1 of the water tank.

[0037] The above examples are only preferred schemes of the present application, and the present application can have other implementation schemes. Those skilled in the art can make equivalent modifications or replacements without departing from the spirit of the present application, and these equivalent modifications or replacements are all included in the scope set by the claims of the present application.
