Abstract

L'invention concerne un dispositif de stérilisation à écoulement, comprenant un boîtier doté d'une entrée d'eau et d'une sortie d'eau, et un cylindre de stérilisation disposé à l'intérieur du boîtier. Un ensemble lampe à DEL est disposé au fond du cylindre de stérilisation ; l'ensemble lampe à DEL et le cylindre de stérilisation entourent une cavité de stérilisation ; un réflecteur est disposé au sommet de la cavité de stérilisation ; un passage d'écoulement d'eau est formé entre le boîtier et le cylindre de stérilisation ; et l'entrée d'eau, le passage d'écoulement d'eau, la cavité de stérilisation et la sortie d'eau sont raccordées en séquence. La lumière ultraviolette profonde émise par l'ensemble lampe à DEL est projetée dans la cavité de stérilisation pour stériliser l'eau qui y circule ; et le réflecteur réfléchit la lumière ultraviolette profonde dans la cavité de stérilisation, de telle sorte que la lumière ultraviolette profonde peut agir de façon répétée sur l'écoulement d'eau afin d'améliorer davantage l'effet de stérilisation sur l'écoulement d'eau. De plus, le réflecteur disposé sur la partie supérieure de la cavité de stérilisation peut réfléchir la lumière ultraviolette profonde vers le bas dans la cavité de stérilisation, de telle sorte que les angles morts dans la cavité de stérilisation peuvent être efficacement stérilisés.
