摘要： A multi-port valve includes a valve housing and a valve core. The valve housing is provided with a plurality of outer ports, at least part of which is arranged at an axial end of the valve housing. The valve core is provided with a plurality of inner ports, at least part of which is arranged at an axial end of the valve core. A plurality of flow channels extends through the valve core, whereas the flow channels are fluidly separated from one another inside the valve core. The plurality of the flow channels includes at least two cross-channels intersecting with each other in a projection plane perpendicular to a rotation axis of the valve core. Each of the flow channels communicates with two of the inner ports. At least part of the inner ports is aligned and communicated with the corresponding outer ports in response to the valve core rotating to a desired position as regarded to the valve housing.

摘要： The invention discloses a magnetic core, which includes a ring-shaped body portion and a plurality of magnetic pole portions connected to the body portion. The magnetic pole portions are arranged on an inner surface of the body portion in a circumferential direction. The body portion and the magnetic pole portions are connected to each other. Each of the magnetic pole portions is triangular and includes a top end and two free ends. The top end is connected to the body portion. Two side surfaces on both sides of the top end of the magnetic pole portion are respectively opposite to and spaced apart from an inner surface of the body portion to form a first receiving groove and a second receiving groove, the first receiving groove and the second receiving groove are used for receiving magnets, and the first receiving groove and the second receiving groove have open ends in an inner surface of the magnetic core. The magnetic core of the present invention has a significant magnetization effect and helps to increase the power density of the motor.

摘要： A multi-stage capacitive sensor is provided having a layered structure, including a user-contact surface, a first capacitive sensor for the user-contact surface, a second capacitive sensor which is spaced apart from the first capacitive sensor in a direction away from the user-contact surface, and a conductive member. The conductive member is positioned between the first and second capacitive sensors, and is engaged with the first circuit substrate and spaced apart from the second capacitive sensor. In a preferred embodiment, under the application of a force at the user-contact surface, the conductive member is deflected relative to the second capacitive sensor to alter a distance therebetween to create a detectable change in a capacitance at the second capacitive sensor.
