In the present embodiment, alarm 14 comprises buzzer and LED light, and the alarm mode of alarm can be when reporting to the police, and buzzer or LED light are worked simultaneously or worked independently.
Referring to Fig. 3, transmitter unit 91 sends infrared ray S1, sidewall 51 1 sides of process liquid-collecting bottle 5 penetrate refraction and enter liquid-collecting bottle 5 interior zones 52, and then penetrate from sidewall 51 opposite sides of liquid-collecting bottle 5, receiving element 92 receives and penetrates the infrared ray S1 that refraction is come, and another part Infrared is through being reflected into reflection ray S2.
Embodiment two
The difference of present embodiment and embodiment one is:
Second detection module 9 only is set, and transmitter unit and receiving element collection are located at together, and referring to Fig. 4, the second detection module 9 is enclosed within on the vertical screw mandrel 10 that extends of a centrage, and screw mandrel 10 centrages are parallel with liquid-collecting bottle 5 above-below directions; Preferably, the second detection module 9 is suffered restraints in screw mandrel 10 centrage circumferential direction, only can be mobile at screw mandrel 10 centerline directions; One end of screw mandrel 10 is connected with motor 11, under the driving of motor 11, screw mandrel 10 is around its centrage rotation, thereby driving the second detection module 9 moves up and down along screw mandrel 10 centrages, the electromagnetic wave signal size that liquid-collecting bottle 5 relevant positions are received detects, so measure whether have transudate with and transparency size.
Wherein, screw mandrel 10 also can be substituted such as in: gear train, belt, the skin wheel any by other drive mechanisms; As long as the second detection module 9 can moved at longitudinal direction with respect to liquid-collecting bottle 5, just can realize detecting the purpose whether liquid-collecting bottle 5 relevant positions have wound fluid and transparency thereof.
The second detection module 9 in the present embodiment, when motor 11 work, driving the second detection module 9 by screw mandrel 10 moves up and down, controller 7 and then according to the stroke of motor, can calculate whether differing heights has transudate and transudate transparency thereof in the liquid-collecting bottle 5, thereby calculate volume and the average transparency of liquid-collecting bottle 5 interior transudates.
Only be preferred implementation of the present invention below, should be pointed out that above-mentioned preferred implementation should not be considered as limitation of the present invention, protection scope of the present invention should be as the criterion with the determined scope of claim.For those skilled in the art, without departing from the spirit and scope of the present invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
