It is understood that target object detection probe 501 is during rotation, it can be opposite with first window 102, with
Human body or animal can be detected.
When the driving end driving pedestal 502 of actuator 503 rotates, pedestal 502 drives 501 turns of target object detection probe
It is dynamic, the detection range of target object detection probe 501 is expanded, conducive to human body is detected.Above-mentioned target-object detecting unit 5
Structure is simple, facilitates manufacture and acquisition.
Based on the structure of above-mentioned target-object detecting unit 5, the rotation direction of target object detection probe 501 be can be set
It is a variety of, two kinds of examples given below:
(1) be used as the first example: as shown in Fig. 3, pedestal 502 includes: the first plate face 5021 and the first plate face 5021

When the rotation of the driving end of actuator 503, the first plate face 5021 of pedestal 502 will be around driving end and the first side wall
5022 rotations.And since target object detection probe 501 is located in the first plate face 5021, so target object detection probe
501 rotate around driving end and the first side wall 5022.Again since the plane where the axis and first window 102 at driving end is flat
Row, end is vertical with the first side wall 5022 connect for driving, therefore the plane of rotation of target object detection probe 501 and first window 102
The plane at place is vertical.
It is understood that target object detection probe 501 is when rotating whole circle, target object detection probe 501 is sometimes
First window 102 can be deviated from, and cannot detect human body.In this regard, the set-up mode about target object detection probe 501, gives

Face 5024, second sidewall 5025；Second plate face 5023 and third plate face 5024 are oppositely arranged, and second sidewall 5025 connects the second plate
Face 5023 and third plate face 5024；Target object detection probe 501 is located in the second plate face 5023；Drive the axis and first at end
Plane where window 102 is vertical, and end is vertical with third plate face 5024 connect for driving.
