Abstract
A photoelectric type movement sensor comprises a light transmitting tube and a light receiving tube which are horizontally arranged in a face-to-face manner, a left pore space and a right pore space are respectively arranged in front of the light transmitting tube and the light receiving tube, a cavity and balls are arranged between the left pore space and the right pore space, and a left concave pit and a right concave pit are respectively arranged in front of the left pore space and the right pore space in cavities. When the movement sensor is in stationary state, the balls are positioned at the bottommost parts of the cavities, light rays emitted by the light transmitting tube are blocked by the balls, and the light rays can not arrive at the light receiving tube; when the photoelectric type movement sensor turns on one side, the balls can roll into the concave pits, and the light rays still can not arrive at the light receiving tube; and when the photoelectric type movement sensor is subjected to the influence of inertia or inclination, the light rays emitted by the light transmitting tube can directly arrive at the light receiving tube after the balls roll away from the bottommost parts of the cavities. The movement state or posture of the sensor can be judged according to different light intensity sensed by the light receiving tube, thus leading electric appliance to response correspondingly.
