1. An inclined detector comprising:

  • a detector body provided with an interior containing space including a lower alcove which is funnel-shaped with a converging circular horizontal cross-section;

    a first detection component including a first transmitting component; and

    a second detection component having a receiving component and a second transmitting component portion, wherein, the first transmitting component is used to transmit a first signal which goes through the said containing space of the detector body, to be received by the receiving component; and

    a ball disposed in the containing space of the detector body, wherein, the ball stays at the bottom center of the lower alcove of the containing space when in a static state, so as to obstruct the first signal transmitted from the said first transmitting component, and the said receiving component will not receive the first signal transmitted from the first transmitting component;

    wherein the first signal transmitted by the first transmitting component is an infrared signal;

    whereby when the detector body is inclined to make the ball leave the former place where the ball is when in a static state, thus, the second transmitting component portion in the receiving component will transmit a second signal for controlling after receiving the first signal transmitted by the first transmitting component.
