Abstract: The present utility model relates to a cup holder, and in particular to a cooling cup holder that is suitable for chairs including massage armchairs, sofas and seats in coaches, airplanes, ships, theaters and cinemas. The cooling cup holder includes a rotary flip so that the cooling cup holder can be covered when it is unnecessary to cool a drink, and the cooling cup holder can be open when it is necessary to cool a drink, thus keeping hygiene of the cooling cup holder. The cooling cup holder may further include a wireless charging station for wirelessly charging a mobile electronic device, for example.

Abstract: Electric valve and a refrigerating system. An inlet, a pressure relief port and a plurality of outlets are set on a valve seat of the electric valve; a valve cap is covered above the valve seat; an electric motor is fixedly set on the valve cap, a stator of the electric motor is set on the outer surface of the valve cap, and a rotor is set in the intracavity of the valve cap; the lower end of a mandrel is fixedly provided with a valve core that is opened with a pressure-relief diversion slot and a through slot, wherein the pressure-relief diversion slot is opened on the lower surface of the valve core, the through slot penetrates through the valve core along the thickness direction of the valve core. Refrigerant bifurcation, cutoff, pressure relief, etc., in refrigerating system is realized by rotating the valve core to different positions.
