Specific implementation mode
Below in conjunction with the accompanying drawings the technical solution of the utility model is further illustrated with embodiment.It is understood that this
The described specific embodiment in place is used only for explaining the utility model, rather than the restriction to the utility model.It further needs exist for
Illustrate, illustrate only for ease of description, in attached drawing with the relevant part of the utility model and it is not all.
Embodiment one
As shown in Figure 1, the present embodiment provides a kind of Level monitor, including optical sensor, the optical sensor include
Light emitting end 12 and optical receiving end 13, the light emitting end 12 are set to the one side wall of water tank 11, and the optical receiving end 13 is arranged
In another side wall of the water tank 11, the light emitting end 12 and the optical receiving end 13 are oppositely arranged；The optical sensor with
The water inlet control valve of the water tank 11 is electrically connected.
When the water level in water tank 11 does not rise to the position of optical sensor, the optical signal that light emitting end 12 is sent out is by light-receiving
End 13 receives completely, and optical sensor exports the first signal at this time；When the water level in water tank 11 rises to the position of optical sensor, by
In water to the absorption characteristic of light, the optical signal that light emitting end 12 is sent out cannot completely be received by optical receiving end 13, at this time light sensing
Device exports second signal；It is the opening and closing of controllable water inlet control valve according to the first signal and the second signal, when optical sensor exports
When the first signal, water inlet control valve is opened, and when optical sensor exports second signal, water inlet control valve is closed.
Further, for the optical sensor that the present embodiment uses for infrared light transducer[sensor, infrared light transducer[sensor has response speed
Spend fast, high certainty of measurement advantage.

The opposite other side of the water tank 21 is provided with reflection wall 24；The water inlet control valve of the optical sensor and the water tank 21 is electrically connected
It connects.
When the water level in water tank 21 does not rise to the position of optical sensor, the optical signal that light emitting end 22 is sent out is through reflection wall
It is received completely by optical receiving end 23 after 24 reflections, optical sensor exports third signal at this time；When the water level in water tank 21 rises to light
When the position of sensor, since water is to the absorption characteristic of light, the optical signal that light emitting end 22 is sent out through reflection wall 24 reflection after not
It can be received completely by optical receiving end 23 completely, optical sensor exports fourth signal at this time；It is according to third signal and fourth signal
The opening and closing of controllable water inlet control valve, when optical sensor exports third signal, water inlet control valve is opened, when optical sensor exports
When fourth signal, water inlet control valve is closed.
In the present embodiment, reflection wall 24 can be coated on the reflective layer on 21 outer wall of water tank；Reflection wall 24 can also
For wall, i.e., when water tank 21 is placed, the other side opposite with the setting side of optical sensor is placed towards wall.
Further, for the optical sensor that the present embodiment uses for infrared light transducer[sensor, infrared light transducer[sensor has response speed
Soon, the advantage of high certainty of measurement.
The light emitting end of Level monitor provided by the utility model and optical receiving end are placed on the outside of water tank, are not being connect
Ensure the real-time monitoring to water level while touching water body, abandons traditional float monitoring (immersion) and the monitoring of water-level detecting needle
(plug-in type) is avoided and is polluted to the water body in water tank.
