Description

Technical Field

[0001] This utility model relates to the field of sanitary ware manufacturing, specifically to a water tank assembly for a smart toilet. Background Technology

[0002] As is well known, smart toilets generally use a flat-bottomed water tank because the electronic control components on the smart toilet seat need to occupy the space above and inside the water tank; otherwise, the seat cannot be opened.

[0003] To address this, a small, half-sized water tank has emerged on the market. It is installed in half of the toilet tank, leaving the other half for the toilet's electrical control components. While this tank meets the installation requirements, its reduced size and insufficient water storage capacity, coupled with the inclusion of components such as the inlet valve inside, make it difficult to meet actual flushing needs. It can only achieve flushing and waste removal through frequent and intensive water replenishment, resulting in a poor user experience and making it unsuitable for wall-mounted or direct-discharge ceramic toilets.

[0004] Subsequently, researchers developed a sunken U-shaped water tank, which is inserted from the rear of the ceramic body and located at the bottom of the ceramic body, leaving the upper space for a smart cover. Although this method increases the water storage volume, its structural limitations mean it can only be placed at the bottom of the ceramic body, making it unsuitable for wall-mounted ceramic bodies. More importantly, it cannot be equipped with an overflow prevention structure. If the pump fails, the water overflowing from the tank cannot be drained into the ceramic body but will instead overflow onto the ground, posing a risk of flooding the ground. At the same time, if the ceramic body becomes clogged, water may flow back into its interior, causing water pollution. This does not meet the international CL standard for backflow prevention. Furthermore, this method can only be connected via a side inlet, and the inlet valve is installed perpendicular to the ground. Therefore, it requires at least two or more turns to connect to the inlet valve. The space occupied by the pipe fittings and connecting pipes is large, making it difficult to meet practical needs.

[0005] In conclusion, existing smart toilet tanks need further improvement. Utility Model Content
