ABSTRACT:
This contact lens sterilization device includes: a main body casing formed as an integral structure, with a main cavity and a power plug storage chamber being defined in the main body casing and being substantially sealed off from communication with one another, the main cavity further being substantially sealed off from communication with the outside, a contact lens sterilization chamber being at least partly defined by a portion of the main body casing which also defines one part of the main cavity; a control system accomodated in the main cavity of the main body casing; a heating system, likewise accomodated in the main cavity of the main body casing, and selectively actuated by the control system to produce heat and to apply the heat to the portion of the main body which partly defines the contact lens sterilization chamber; a power plug assembly, received in the power plug storage chamber, and comprising a pair of terminal portions which according to movement of the power plug assembly within the power plug storage chamber selectively either can be projected to the outside from the power plug storage chamber or can be withdrawn to the inside of the power plug storage chamber; and: a pair of fixed contacts fitted so as electrically to connect portions of the control system to the terminal portions of the power plug assembly. Thereby, advantages of durability and compactness are made available, and the ingress of moisture and dirt is positively prevented.
