Abstract: An electrochromic film, an electrochromic device and a method for manufacturing the same, electrochromic glass, and a vehicle are provided. The electrochromic film includes a first transparent conductive layer, a second transparent conductive layer, and an electrochromic functional layer. Each transparent conductive layer is provided with multiple electrode sub-lines arranged at intervals on an edge of at least one side of said each transparent conductive layer. On a plane where the first transparent conductive layer or the second transparent conductive layer is located, orthographic projections of the multiple electrode sub-lines of the first transparent conductive layer have at least a non-overlapping part with orthographic projections of the multiple electrode sub-lines of the second transparent conductive layer. The electrochromic functional layer is disposed between the first transparent conductive layer and the second transparent conductive layer.

Abstract: A gas detection device includes a casing, a detection unit, and a circuit board. The detection unit is electrically connected to the circuit board. The detection unit includes a detection casing and has an air chamber. The detection casing is located on the periphery of the air chamber and has a mating hole in communication with the air chamber. The casing has a ventilation hole. At least part of the detection unit is located inside the casing, and at least part of the circuit board is located inside the casing. The ventilation hole is in communication with the mating hole and also in communication with the outside of the gas detection device. The casing is one integral piece. This simplifies the manufacturing and installation process.

Abstract: A extended-time release method includes the following steps: mixing water with the toilet cleaner to form an initial solution when water enters a bowl; starting release of the initial solution while water level in the bowl returns to normal; and continuing release of the initial solution after the water level in the bowl returns to normal, in which a mixed liquid of the initial solution and the water in the bowl is referred to as a primary solution; in the above method, the volume of the initial solution is not less than 10 ml; and the content of the effective ingredients of the toilet cleaner in the primary solution is not less than 2 ppm.
