[0049] refer to Figure 4 and Figure 5 It should be noted that the shape of the decorative handle 311 includes, but is not limited to, circles, squares, etc.
[0050] refer to Figure 4 and Figure 5 It should be noted that in this embodiment, the shapes of the second drain hole 420 and the third drain hole 510 are adapted to the shape of the decorative handle 311. For example Figure 4This illustrates that when the decorative handle 311 is set as a square, the shapes of the second drain hole 420 and the third drain hole 510 are correspondingly set as squares; for example... Figure 5 This illustrates that when the decorative handle 311 is set to a circle, the shapes of the second drain hole 420 and the third drain hole 510 are correspondingly set to circles.
[0051] It should be noted that in other embodiments, the shapes of the second drain hole 420 and the third drain hole 510 may not be compatible with the shape of the decorative handle 311. For example, the shapes of the second drain hole 420 and the third drain hole 510 may be square, while the shape of the decorative handle 311 may be circular. Alternatively, the shapes of the second drain hole 420 and the third drain hole 510 may be square, while the shape of the decorative handle 311 may be clover-shaped. Any solution in which the decorative handle can be accommodated within the second drain hole 420 and the third drain hole 510 should be protected.

By providing these clearance spaces 313, users can insert their fingers into the clearance spaces 313, press against the side walls of the clearance spaces 313, and grip the side walls to easily remove the quick-cleaning structure 300 from the fixing block 500. This makes operation convenient. It is understandable that if ease of grip is not a consideration, the clearance spaces 313 could be omitted; any design that allows the quick-cleaning structure 300 to be detached from the drain body 100 should be protected.
[0053] refer to Figure 1 It should be noted that in this embodiment, the upper surface of the floor tile 200 is flush with the upper surface of the decorative handle 311, which increases the overall aesthetics of the floor. Furthermore, users will not bump their feet if the upper surface of the decorative handle 311 is higher than the upper surface of the floor tile 200, nor will their feet get stuck in the fixing block 500 if the upper surface of the decorative handle 311 is lower than the upper surface of the floor tile 200, thus enhancing user safety in the bathroom. It is understandable that, without considering safety and aesthetics, the upper surfaces of the floor tile 200 and the decorative handle 311 may not be flush.
[0054] It should be noted that in this embodiment, the handle 310 also includes a connector 330, a third magnetic 340, and a fourth magnetic 350. The connector 330 is disposed between the filter basket 320 and the extraction rod 312. The opposite ends of the third magnetic 340 are magnetically attracted to the extraction rod 312 and the connector 330, respectively. The opposite ends of the fourth magnetic 350 are magnetically attracted to the filter basket 320 and the connector 330, respectively, to achieve a detachable connection between the filter basket 320 and the extraction rod 312, making operation convenient. By detaching the filter basket 320 from the extraction rod 312, the user can flip the filter basket 320 to remove the waste. It is understood that the connector 330, the third magnetic 340, and the fourth magnetic 350 may also be omitted. For example, the filter basket 320 and the extraction rod 312 can be threaded together. Any scheme that allows for a detachable connection between the filter basket 320 and the extraction rod 312 should be protected.
[0055] By setting the decorative handle 311 and the extraction rod 312 to be detachably connected, and the extraction rod 312 and the filter basket 320 to be detachably connected, when cleaning the garbage in the filter basket 320, the user can choose to detach the decorative handle 311 to the extraction rod 312, or choose to detach the filter basket 320 to the extraction rod 312. Multiple options are available, making operation convenient.
[0056] refer to Figure 2 and Figure 3 The filter basket 320 has a first end 322 and a second end 323 along its height.
