Abstract: An interdental cleaning device is adapted for use with a dental floss roll and includes a main body and a floss holder. The main body defines a receiving space configured to receive the dental floss roll. The floss holder is pivotally connected to the main body and defines a guiding channel that is in spatial communication with the receiving space. The floss holder has a securing end, and an open end that is spaced apart from the securing end and that is formed with an opening to spatially communicate the guiding channel with external environment. A to-be-used segment of the dental floss roll is extendible through the opening of the open end via the guiding channel so as to be secured at the securing end of the floss holder.

Abstract: The current convertor comprises a current converting device and a sliding cover. The current converting device comprises a casing, a current converting module arranged inside the casing, two conductive terminals electrically connected to the current converting module, and a first sliding module disposed on the casing. The conductive terminals are partially exposed from the casing. The sliding cover has a second sliding module having two thru holes. The second sliding module is slidably disposed on the first sliding module for enabling the sliding cover to slide between a first position and a second position relative to the casing. When at the first position, the conductive terminals pass through the thru holes of the sliding cover for inserting into the conventional outlet, and when at the second position, the conductive terminals are arranged in a space surrounded by the sliding cover and the casing.

Abstract: The current convertor comprises a current converting device and a combinative plug. The current converting device comprises a casing and a current converting module arranged in the casing. The casing has at least one track extended from an outer surface of the casing along a sliding direction. The combinative plug comprises an insulating body and a conductive pin set disposed on the insulating body. The insulating body has a quick releasing portion conformed in shape to the track. The quick releasing portion is detachably sliding on the track of the casing along the sliding direction for maintaining the relative position between the current converting device and the combinative plug and for establishing electrical connection between the conductive pin set and the current converting module.
