Abstract: A force detection and transmission mechanism for a pedal includes a pedal body, a force detection module, a rotation shaft, an insulating sleeve, electrically conductive rings, and contact elements. The pedal body has a first accommodating space and a second accommodating space. The force detection module is disposed in the first accommodating space. The rotation shaft passes through the pedal body. Annular accommodating regions and wire perforations are recessed from a surface of the rotation shaft. Transmission wires pass through the wire perforations. The insulating sleeve is sleeved on the rotation shaft. Annular insulating regions are recessed from a surface of the insulating sleeve and correspondingly cover the annular accommodating regions. The electrically conductive rings are respectively sleeved on surfaces of the annular insulating regions, and the transmission wires are correspondingly coupled to the electrically conductive rings. The contact elements abut against the electrically conductive rings, respectively.

Abstract: A rotary dewatering mop device comprises an outer casing, a barrel, a cleaning assembly and a holding assembly. The cleaning assembly is pulled upward through the holding assembly to be placed in the barrel and is moved upward and downward reciprocatically through a handheld rod to drive the barrel and the cleaning assembly to generate a centrifugal force of rotation, thereby achieving rapid dewatering.

Abstract: The present invention provides a telescopic storage can structure, which comprises a can, a hood and a cover. The can is disposed with an airtight member at an opening, and the hood is covered on the can and formed with an upper opening. The cover is disposed on the upper opening and formed with an air outlet and disposed with an air outlet valve assembly. The hood can be upwardly and downwardly displaced on the can according to a holding capacity, and when the hood is displaced downwardly, the cover will squeeze the internal air thereof and the internal air is sent out through the air outlet. Thereby achieving an effect of being able to adjust a size according to a holding capacity and facilitate an airtight purpose, and further, relative positions of the can and the hood can be telescopically adjusted according to a storage capacity.
