Description

Electromagnetic valve

Technical Field

Background

With the continuous progress of technology, intelligent toilets become an indispensable part of people's life. Compared with the traditional closestool, the intelligent closestool has more intelligent and humanized design and more comfortable and sanitary use experience. However, with the popularization of intelligent toilets, problems also occur, one of which is the problem of clogging of the spray gun holes due to scale.

Scale is a white precipitate formed by the combination of calcium, magnesium and carbonate in water. In northern areas, the hardness of water is high, and calcium and magnesium ions are more contained, so that the problem of scale is more remarkable. After the intelligent closestool is used for a period of time, scale can be formed on the spray gun hole, so that water flow is unsmooth and even is blocked completely, and normal use of the intelligent closestool is affected.

In order to solve the problem, the intelligent toilet manufacturers currently adopt various technical means, wherein a common method is to install a filter at a spray gun hole, and impurities in water are filtered through the filter, so that the generation of scale is reduced. On the basis, some intelligent toilets are further provided with a scale inhibition box filled with scale inhibition materials in the filter screen, and the method can further reduce impurities in water, but has some disadvantages. Firstly, the filter needs to be cleaned or replaced regularly, otherwise, the filter effect is blocked or reduced, and the normal use of the intelligent closestool is affected. Second, the filter can only filter impurities in water, but cannot completely solve the problem of scale.
