Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
Embodiment 1: as shown in Figure 1, a kind of liquid level monitoring device, comprising: staving 1 is respectively arranged at 1 highest of staving and most
The detection components 2 of low liquid level；It is connected to the connecting pipe 3 of two detection components 2；Be opened on 1 highest liquid level of staving into
Port 4；And drawing liquid pump 5；Drawing liquid pump 5 is used for the supplement liquid into staving 1 or stops supplement liquid, in upside detection components 2
Edge is located at the highest liquid level of staving 1, and detection components 2 lower edge in downside is located at the minimum level of staving 1.
As shown in Figs. 1-2, detection components 2 include: pressure membrane 22；It is connected to the detection of connecting pipe 3 close to 1 side of staving
Instrument 21；And it is set to the pressure switch 23 in detector 21, detector 21 is installed for pressure membrane 22, when 22 direction of pressure membrane
Pressure switch 23 will be triggered when protruding outside staving 1, detector 21, being capable of pressure supply in being open towards the bowl-shape shape inside staving 1
Power film 22 makes different degrees of protrusion reaction under the different pressure of staving 1, and to a certain extent, has saved and be fabricated to
This, pressure switch 23 supplements liquid or stopping supplement liquid, and the opening face of air inlet 4 into staving 1 for controlling drawing liquid pump 5
The sum of the area that product is equal to two pressure membranes 22 is in so that staving 1, when vacuumizing, the pressure of 22 two sides of pressure membrane is consistent
Pressure balance, while disrepair phenomenon, Jin Er will not occur for while also ensuring that pressure membrane 22 by higher pressure in staving 1
When staving 1 accommodates liquid, pressure membrane 22 can make accurate response to liquid pressure, to carry out accurate detection to liquid level.
Upper and lower two detection components 2 carry out level sensing to 1 different location of staving respectively, when the liquid in staving 1 is only enough
When to lowest point, for the pressure membrane 22 in downside detection components 2 by the pressure in bucket, pressure membrane 22 is directed away from staving 1
For side protrusion until being triggered to pressure switch 23, pressure switch 23 controls the drawing liquid pump 5 outside staving 1 to mending in staving 1
Filling liquid body, when the liquid in bucket reaches highest point in bucket, the pressure membrane 22 in upside detection components 2 is by the pressure in bucket
By force, therefore pressure membrane 22 is directed away from 1 side of staving and is protruding to triggering pressure switch 23, and pressure switch 23 cuts off the work of drawing liquid pump 5
It switchs, so that drawing liquid pump 5 stops to supplementing liquid in staving 1, and then realizes and the liquid in staving 1 is monitored automatically, and should
Detection components 2 are not easy to detect failure under negative pressure state, can accurately the liquid level in bucket be detected and be regulated and controled.
Embodiment 2: as shown in Figure 1, a kind of liquid level monitoring device, comprising: staving 1 is respectively arranged at 1 upper and lower ends of staving
Detection components 2；It is connected to the connecting pipe 3 of two detection components 2；The air inlet 4 being opened on 1 highest liquid level of staving；
And drawing liquid pump 5；Drawing liquid pump 5 is used to supplement liquid into staving 1 or stops supplement liquid, and detection components 2 upper limb in upside is located at
The highest liquid level of staving 1,2 lower edge of downside detection components are located at the minimum level of staving 1.
Unlike the first embodiment, as shown in figures 1 and 3, detection components 2 include: pressure membrane 22 to the present embodiment；Connection
In connecting pipe 3 close to the detector 21 of 1 side of staving；It is in detector 21 and for detect pressure membrane 22 whether direction

Detection signal is pressure membrane 22 when protruding into predeterminated position, and controller controls drawing liquid pump 5 to carrying out supplement liquid in staving 1 or stop
Only supplement liquid.
When the liquid in staving 1 only gets at lowest point, the pressure membrane 22 in downside detection components 2 is by bucket
Pressure, pressure membrane 22 are directed away from 1 side of staving and are protruding to predeterminated position, and sensor 24 detects the signal at this time, and then will
The signal passes to controller, and controller controls the drawing liquid pump 5 outside staving 1 to supplement liquid is carried out in staving 1, when in bucket
When liquid reaches highest liquid level in bucket, pressure membrane 22 in upside detection components 2 is by the pressure in bucket, therefore pressure membrane 22
It is directed away from 1 side of staving and is protruding to predeterminated position, the signal that sensor 24 will test passes to controller, controller control
Drawing liquid pump 5 realizes the automatic monitoring to staving 1, and the detection components 2 are not easy negative to stopping supplement liquid in staving 1
Failure is detected under pressure condition, can accurately the liquid level in bucket be detected and be regulated and controled.
The use principle of the present embodiment is approximately as stating: upper and lower two detection components 2 are used for the highest and lowest liquid of staving 1
Position is detected, and air inlet 4 is used to guarantee the pressure values of two 2 other sides of detection components, to ensure to vacuumize in staving 1
When, disrepair phenomenon will not occur for pressure membrane 22, the pressure membrane 22 when liquid level reaches certain value in bucket, in detector 21
1 side of staving protrusion is directed away under pressure action in staving 1, and then pressure membrane 22 can trigger pressure switch 23, pressure is opened
It closes and carries out supplement liquid in 5 pairs of buckets of drawing liquid pump outside 23 control stavings 1 or stop supplement liquid, exist by using pressure membrane 22
Pressure is directed away from 1 side of staving protrusion, and then the mode of the pressure switch 23 of 21 side of detection trigger instrument when reaching certain value,
Liquid level in bucket can be automatically controlled, and detection components 2 are not easy to detect failure under negative pressure state, detection effect are improved, with energy
It is enough that accurately the liquid level in bucket is detected and regulated and controled, while the scope of application is wider.
