Abstract: A gas detection and cleaning system for a vehicle is disclosed and includes an external modular base, a gas detection module and a cleaning device. The gas detection module is connected to a first external connection port of the external modular base to detect a gas in the vehicle and output the information datum. The information datum is transmitted through the first external connection port to a driving and controlling module of the external modular base, processed and converted into an actuation information datum for being externally outputted through a second external connection port of the external modular base. The cleaning device is connected with the second external connection port through an external port to receive the actuation information datum outputted from the second external connection port to actuate or close the cleaning device.

Abstract: A tile fixing strip comprising a plurality of convex pieces and concave pieces, wherein, neighboring convex pieces and concave pieces are fastened to each other. The convex piece and the concave piece respectively has the formation of a dent, so that when the entire tile fixing strip is arranged crosswise on the slope of a house roof to accommodate the placement of the tiles, the joined convex pieces and concave pieces provide accommodation to fasten the tiles. The reinforced surface shape and structural strength of the convex pieces and concave pieces will prevent deformation. The dents of the convex pieces and concave pieces provide channels for heat radiation, ventilation and rainwater drainage to the tiles on the slope of a house roof. To conclude, it is a tile fixing strip that is resistant to deformation, contributing to heat radiation, ventilation and water drainage.
