Abstract

La présente invention concerne un stérilisateur à ultraviolets ayant une fonctionnalité de protection contre la mise hors tension, comprenant : un boîtier, un tube de lampe à ultraviolets et un fil de douille de lampe. Le boîtier enveloppe le tube de lampe à ultraviolets. Une extrémité du tube de lampe à ultraviolets est reliée de manière amovible au fil de douille de lampe. Le boîtier est pourvu d'un élément de limitation. L'élément de limitation peut être déplacé entre une position d'arrêt et une position d'évitement. Lorsque l'élément de limitation est situé au niveau de la position d'arrêt, le tube de lampe à ultraviolets est verrouillé dans le boîtier et le fil de douille de lampe est séparé du tube de lampe à ultraviolets sous l'action d'une force externe. Après que le fil de douille de lampe est séparé du tube de lampe à ultraviolets, l'élément de limitation est changé de la position d'arrêt à la position d'évitement sous l'action d'une force externe pour déverrouiller le tube de lampe à ultraviolets. Le stérilisateur à ultraviolets ayant une fonctionnalité de protection contre la mise hors tension selon la présente invention peut être mis hors tension automatiquement pendant le désassemblage du tube de lampe à ultraviolets, de sorte que le corps humain est protégé des dommages causés par des rayons ultraviolets. En verrouillant/déverrouillant le tube de lampe à ultraviolets par l'intermédiaire de l'élément de limitation, la présente invention est appropriée pour des tubes de lampe à ultraviolets classiques, et présente de faibles coûts de remplacement.
