## Abstract

An inclined detector comprises: a detector body provided with an interior containing space including a lower alcove which is funnel-shaped; a pair of detection components including a transmitting component and a receiving component, wherein, the transmitting component is used to transmit a first signal which goes through the said containing space of the detector body, and the receiving component is used to receive the first signal transmitted by the transmitting 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. By such arrangements, when the detector body is inclined to make the ball leave the former place where the ball is when in a static state, the receiving component will transmit a second signal for controlling after receiving the first signal transmitted by the transmitting component.

## Claims

### Claim 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.

### Claim 2 (depends on 1)

The inclined detector as claimed in claim 1, wherein the detector body includes an upper rind and a lower rind.

### Claim 3 (depends on 2)

The inclined detector as claimed in claim 2, wherein the upper rind is provided with an upper alcove which is funnel-shaped with a converging circular horizontal cross-section.

### Claim 4 (depends on 1)

The inclined detector as claimed in claim 1, wherein the first transmitting component and the receiving component are correspondingly disposed at the outside of the containing space of the detector body.
