Referring to fig. 1 and 4, in an embodiment, a display window 400 is disposed on a sidewall of the water tank 100, and one end of the floating structure 202 is aligned with the display window 400. In use, one end of the floating structure 202 protrudes into the tank 100 and can be raised or lowered as the water level in the tank 100 changes. By aligning one end of the floating structure 202 with the display window 400, thereby facilitating viewing of the floating structure 202 through the display window 400, a particular location of the water level within the tank 100 is facilitated to be determined by the one end of the floating structure 202.

In one embodiment, the display window 400 is a transparent member embedded in the sidewall of the water tank 100, and the display window 400 is provided with scales so that the amount of the water level in the water tank 100 can be observed through the display window 400. Specifically, a bar-shaped through hole is formed in the side wall of the water tank 100 and is arranged in the vertical direction, and the transparent member is arranged at the through hole and covers the through hole, so that the water level of the water tank 100 can be observed conveniently through the transparent member.

In one embodiment, the float 232 of the indicator 230 is aligned with the display window 400, so that the water level in the water tank 100 can be judged by observing the position of the float 232. Optionally, the floating portion 232 is red, so that the user can effectively observe the floating portion 232 and further effectively determine the water level in the water tank 100. In other embodiments, the float 232 may be other colors as well, as long as viewing is facilitated.

Optionally, the guide 300 is disposed at the display window 400, and a length direction of the guide 300 and a length direction of the display window 400 are both vertical directions. And thus, when the floating portion 232 floats along the guide 300, the floating portion 232 can be stably aligned with the display window 400 at all times, further ensuring the stability of observation.

In other embodiments, the floating structure 202 may also include only the floating portion 232, and during the water filling process, the position of the floating portion 232 is observed through the display window 400, so as to determine the water level in the water tank 100.

In one embodiment, the floating structure 202 may include only the water deflector 220. When adding water to the highest water level, or add water to the position that is close to the highest water level, block up water injection hole 211 through water blocking piece 220, and then avoid continuing to add water to holding in the chamber 110, realize the effective judgement of whether filling up water in holding the chamber 110. In another embodiment, the floating structure 202 may also include only the indicator 230. When water is added to the highest water level or the position close to the highest water level, the indicator 230 floats upwards and can protrude from the indicating hole 216, so that it is convenient to judge that the accommodating cavity 110 is filled with water. In other embodiments, the floating structure 202 may include both the water blocking member 220 and the indicating member 230, so as to further improve the accuracy and stability of the determination of whether the accommodating chamber 110 is filled with water.
