Specific implementation mode
The technical solution further illustrated the present invention below in conjunction with the accompanying drawings with embodiment.It is understood that this place
The specific embodiment of description is used only for explaining the present invention rather than limitation of the invention.It also should be noted that in order to
Convenient for description, in attached drawing, only the parts related to the present invention are shown and it is not all.
Embodiment one
Referring to Fig. 1 and Fig. 2, a kind of water level turbidity detection device, can be used for the turbidity of sensed water level and water, including light sensing
Device 1, baffle 2 and float 3.
Optical sensor 1 includes spaced transmitting terminal 11 and receiving terminal 12, the light that transmitting terminal 11 is sent out, by receiving terminal 12
It receives, is converted to current signal.Float 3 is connect with baffle 2, and float 3 is hollow-core construction, and float 3 is lifted with the lifting of water level,
And baffle 2 is driven to can be alternatively positioned at being in the light at position between transmitting terminal 11 and receiving terminal 12.Therefore, when baffle 2 is located at gear
When optical position, the light that transmitting terminal 11 is sent out is blocked, receiving terminal 12 is caused not receive light, current signal is low-level；When baffle 2
It leaves when being in the light position, the light receiving end 12 that transmitting terminal 11 is sent out receives, and current signal is high level.Baffle 2 is from positioned at gear
To position of being in the light is left, current signal can mutate optical position, therefore more easily determine water level.
By the way that float 3 and baffle 2 link together, under the drive of buoyancy, baffle 2 is moved, to being located at or
Position of being in the light is left, the light that the transmitting terminal 11 of optical sensor 1 is sent out can be blocked or is not blocked, the reception of such optical sensor 1
The amplitude for the light variation that end 12 receives just very greatly, increases the accuracy rate of judgement, for detection of intaking, completes water inlet detection
Afterwards, baffle 2 no longer blocks, so that it may to judge the turbidity of water by judging the size of electric current；It is simple in structure, easy to use, section
About cost, accuracy are high.
Further include position-limit mechanism, position-limit mechanism includes float lever 4 and the stop collar 5 that is set on float lever 4, float lever 4
Both ends be separately connected baffle 2 and float 3.Float lever 4 can be integrally formed with baffle 2, easy to process, save material, be saved
Production cost.Float lever 4 can be detachably connected with baffle 2, be such as connected through a screw thread, and be easily installed, and when failure, just
In replacement, maintenance cost is saved.With the lifting of water level, float lever 4 moves back and forth in stop collar 5, and stop collar 5 plays guiding
With the effect of limit.The internal coat of stop collar 5 has ceramic wearing coat, reduces abrasion.
The cross section of float lever 4 is rectangle, is not in the problem of itself is rotated during moving up and down in this way, keeps away
Exempt from signal fluctuation, ensure that the accuracy of testing result.
The cross-sectional area of baffle 2 is more than the cross-sectional area of float lever 4, in this way, the mistake that float lever 4 moves in stop collar 5
Cheng Zhong, stop collar 5 play the role of limit to baffle 2 so that baffle 2 does not fall out stop collar 5.
Optical sensor 1 can be infrared light transducer[sensor 1, and transmitting terminal 11 is spaced with receiving terminal 12 to be arranged and be electrically connected.
Embodiment two
A kind of dish-washing machine, including sink and above-mentioned water level turbidity detection device, water level turbidity detection device is removably
It is set on the madial wall of sink.Water level turbidity detection device is located at away from bottom of gullet certain altitude, this height value is according to washing
The actual conditions setting of bowl machine.Optical sensor 1 is connect with the madial wall of sink, and stop collar 5 is also connect with the madial wall of sink.
Optical sensor 1 is just placed on the inner wall of sink, and float 3 is located at the top of optical sensor 1, for detecting high water level；
Optical sensor 1 is inverted on the inner wall of sink, and float 3 is located at the lower section of optical sensor 1, for detecting low water level.When water level arrives
Up at float 3, float 3 rises with water level and is risen, and then baffle 2 is driven to leave position of being in the light.It disclosure satisfy that different uses
Demand, simple in structure, easy to use, cost-effective, the high advantage of accuracy.
Embodiment of above is to elaborate that the basic principle and characteristic of the present invention, the present invention are not limited by the above embodiment
System, without departing from the spirit and scope of the present invention, the present invention also has various changes, these changes and modifications are all
It falls into scope of the claimed invention.The claimed scope of the invention is by appended claims and its equivalent circle
