A temperature indicator (101) is adapted to be provided on a surface (116) for providing a first type of light emission and a second type of light emission (L2). The temperature indicator (101) comprises a light-emitting diode (108) for providing said first type of light emission and a light-emitting electrochemical cell (109) for providing said second type of light emission (L2). The light-emitting electrochemical cell (109) has a first electrode (120), a second electrode (121) and a second light-emitting layer (113) being sandwiched between them and comprising a matrix and ions being movable in the matrix, the mobility of said ions in said matrix being temperature dependent. A power source (105) is adapted for driving the cell (109) with an AC voltage, the frequency of which is tuned in such a way that the cell (109) provides said second type of light emission (L2) when the surface temperature exceeds a certain level.

The invention discloses a dual-purpose openable-closeable-topped two-wheeled saloon car steered through a push-pull rod. The dual-purpose openable-closeable-topped two-wheeled saloon car steered through the push-pull rod comprises an original car body, a front wheel, a rear wheel, a brake device and a main motor. A car cover for a user to get on or off is installed at the upper portion of the car body. A dual-purpose openable-closeable-topped car roof cover is installed at the upper portion of the car cover. A steering push-pull rod device installed on a front wheel steering handle is high in freedom degree, the user can comfortably drive the car on the ground or by at a high or low position and control running steering, car speed and braking. Supporting wheels are installed on two sides of the car, a driver in the car operates the supporting wheels to be in contact with the ground or lift the supporting wheels so as to perform car supporting or parking through a foot-controlled foot pedal, the supporting wheels are in contact with the ground to lock the three-wheeled running car and are wind-resistant, and the car speed is the same as the speed of the saloon car when the three-wheeled running car is lifted by the supporting wheels. During emergency braking, safety supporting feet on two sides of a car head and the supporting wheels can be propped up to the ground to achieve safe parking in a four-foot mode. A single-seat saloon car and a saloon car for two and a half (child) are provided. The low car body of the saloon car is 1.18 meters, the wide supporting wheel distance is 1.10 meters, and the saloon car is small in wind resistance, safe in running and capable of saving energy, reducing haze and relieving traffic jam and can be driven on the road after a certificate is issued.

The invention comprises a main valve body, a water inlet, a water outlet and a valve body with an opening, wherein the valve body with the opening and the water inlet are provided with a valve formed by three valve plates which are closely connected; the upper parts of the valve plates are provided with seal pads, connecting bolt sleeves and main valve bodies, while the lower parts are provided with seal pads, valve bodies and filter screens; the middle valve plate is connected with a driven member and a switch piece; and during opening or closing, the switch piece, the driven member, a driven valve plate and the seal pads do not contact or generate friction so as to prevent the seal pads from being worn. By adopting the structure, the water tap can be instantaneously opened or closed through the switch piece so as not to cause resource waste, and has no wearing parts, thereby prolonging the service life.
