Abstract: An ionizer incorporated with an electronic appliance utilizes the power supply of the appliance so that only less device and space are required for the additional ion function. The small power-consumption ionizer does not influence the original function of the electronic device while the negative ions help refreshing the air and improving people's moods, energy and health.

Abstract: An artificial knee joint includes an upper seat, a lower seat adapted to be connected fixedly to a prosthetic lower leg, and a driving device. The upper seat includes a seat body connected to the lower seat by the driving device, and a movable member connected pivotally to the seat body and adapted to be connected fixedly to a residual thigh.

Abstract: An artificial knee joint connects a prosthetic lower leg to a residual thigh of a prosthesis wearer, and includes a knee-extending oil passage and a knee-flexing oil passage that is provided with a throttle valve. When the lower leg is pressed against the ground by the thigh, a controlling element activates the throttle valve to close the knee flexing oil passage so as to fix the thigh relative to the lower leg. Upon fast walking of the wearer, an air valve unit activates the throttle valve to reduce flow rate of oil flowing through the knee-flexing oil passage so that the lower leg can support the thigh effectively.
