Seventh look: look at ceramics: after all, this is the most basic part. Good ceramics are durable, will not easily crack, will not be yellow and smelly;
Second, look at the glaze: a good glaze is smooth and delicate, easy to rinse and not dirty, and self-cleaning glaze is the first choice;
Third, look at the firing process: the toilet with good effect has a high degree of porcelain, and the ceramics are firm and dense, and will not be loose and rough;
Fourth, look at the water part: the part in the water tank that is responsible for flushing. Pay attention to the choice of big brands, durable and water-saving, and the flow and impulse are appropriate, so that it is clean.
Fifth, look at the seat ring and cover plate: it has a good cushioning and mute effect, will not come down directly with a bang, feels warm and comfortable, is detachable and easy to clean, and will not crack and deform.
Sixth, look at the nozzle material: there are resin and stainless steel, the former is easy to take care of and the latter is more durable.
Seventh, look at electronic components: if the ordinary toilet is ceramic+water, then the smart toilet is ceramic+electronic components, so it depends on safety, whether there will be water leakage, how the protective measures are done, and the functions are not complete.
