There are various applications of 12V water pumps in smart toilets, aimed at improving hygiene, comfort, and user experience. Here are some possible applications:

Flushing system: A 12V water pump is commonly used in the flushing system of smart toilets. These water pumps can provide sufficient water pressure to ensure effective cleaning during flushing. Some advanced smart toilets may have different flushing modes, such as forward flushing, backward flushing, massage flushing, etc., which may require different water flow intensities and directions.

Warm water flushing: Some advanced smart toilets are equipped with warm water flushing function, requiring a water pump to provide sufficient water flow and pressure. This can increase the comfort of flushing, especially in cold seasons.

Air drying system: The air drying system in smart toilets usually uses air drying to replace traditional tissues. A water pump may be used to provide the air pressure required during the drying process.

Odor control system: Some smart toilets may be equipped with an odor control system, which can improve the user's environmental comfort by inhaling the odor into the system and sending it to the water pump or filter.

Seat heating system: The smart toilet may also include seat heating function, which uses a water pump to transfer heated or cold water to adjust the temperature of the seat, providing a more comfortable sitting experience.

These applications help improve the hygiene standards of smart toilets and provide a more user-friendly user experience. It should be noted that with the continuous development of technology, the functions and applications of smart toilets are also constantly expanding, so the specific applications may change.
