Detailed description of the invention
It should be noted that in the case of not conflicting, the embodiment in the application and the feature in embodiment can phases
Combination mutually.Describe the present invention below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
As it is shown in figure 1, the float liquid level switch of the present embodiment, including the float 10 moved longitudinally and coordinate with float 10
Liquid-level switch 20, float 10 has the primary importance making liquid-level switch 20 turn on and the second making liquid-level switch 20 disconnect
Put.
In the float liquid level switch of the present embodiment, float is connected with liquid-level switch, when float is in by action of gravity
During home position, i.e. during the second position, float makes liquid-level switch disconnect；Move longitudinally upward when float is by buoyancy of water,
When float is moved upward to primary importance, the liquid-level switch conducting coordinated with float.So by float by buoyancy longitudinally
Mobile judge water level and control liquid-level switch to carry out monitoring water level, compared to existing technology in liquid-level switch passed by pressure
For sensor and controller etc. carry out monitoring water level, simple in construction, take up room little, and save and used some soft and hardwares, save
Production cost.
Preferably, float 10 has the connection through hole 11 extended transversely；Liquid-level switch 20 includes Switch main body 21 and connects
Contact pin 23, Switch main body 21 has corresponding to connecting the conducting contact in the middle part of sheet 23, and the first end connecting sheet 23 connects pivotly
Be connected on Switch main body 21, the second end is located in connection through hole 11, and float 10 connects the middle part of sheet 23 when being positioned at primary importance
With conducting contact so that liquid-level switch 20 turns on, float 10 connects middle part and the conducting contact of sheet 23 when being positioned at the second position
Separate so that liquid-level switch 20 disconnects.
Wherein it is desired to special instruction, connect in sheet 23 second end is located in connection through hole 11 and include two kinds of sides of wearing
Formula, the first wears mode and passes completely through connection through hole 11 for connecting sheet 23 second end；The second wears mode for connecting sheet 23
Second end section penetrates in connection through hole 11；Both wears mode and all can reach the connection effect connecting sheet 23 and connection through hole 11
Really, connect sheet 23 employing in the present embodiment wears mode for the first, referring specifically to Fig. 1.
Preferably, the inwall connecting through hole 11 is more than the thickness connecting sheet 23 in vertical spacing.Due to the present embodiment
In float liquid level switch, connecting through hole 11 is manhole, i.e. connects the diameter of through hole 11 more than the thickness connecting sheet 23.So
Arrange, will reach to be dynamically connected the effect of sheet 23 by band during float 10 rises or decline certain distance.Float
10 processes declined are referring specifically to Fig. 3 to Fig. 5, and more specifically effect is: when float 10 is moved longitudinally upward by buoyancy
Moving and make liquid-level switch 20 turn on to primary importance, liquid-level switch 20 is the operating of general draining pump when turning on, and is discharged by unnecessary water, water
When position declines, float declines therewith, owing to connecting the diameter thickness more than connection sheet 23 of through hole 11, when float drops to the company of making
When contact pin 23 contacts with the inwall the top connecting through hole 11, connect sheet 23 and just driven and make the middle part of connection sheet 23 by float 10
With conducting contact separation, final liquid-level switch 20 disconnects.The difference coordinated by the contact connecting through hole 11 be connected sheet 23, is kept away
Exempt to connect sheet 23 and caused liquid-level switch 20 to turn on because of the small mobile change of float 10 and disconnect problem frequently, extended
Life-span of liquid-level switch and draining pump.
Preferably, the concrete structure of the float liquid level switch of the present embodiment is as follows: float 10 includes the first cylinder 13 and connects
Being connected on second cylinder 15 of first cylinder 13 one end, the diameter of the second cylinder 15 is less than the diameter of the first cylinder 13, the second cylinder
15 have connecting portion away from one end of the first cylinder, and connecting portion is provided with connection through hole 11.Float 10 also includes being arranged on floating
Stopper section 17 on the outer wall of son 10, stopper section 17 extends radially outward.
Present invention also offers the embodiment of external water pump, referring specifically to Fig. 2 to Fig. 5, external water pump include water tank 31, every
Plate 33 and the float liquid level switch of above-described embodiment, dividing plate 33 is horizontally set on the top of water tank 31, and liquid-level switch 20 is arranged on
On dividing plate 33, float 10 is arranged in water tank 31.Dividing plate 33 has pilot hole, and the second cylinder 15 is located in pilot hole movably
In, the diameter of pilot hole is less than the diameter of the first cylinder 13.Dividing plate 33 has the limiting plate extended towards vertically downward direction, spacing
It is provided with on plate and the locating part of stopper section 17 clamping matching.
Wherein, by the second cylinder 15 and the cooperation of pilot hole, make float 10 can prolong longitudinally upward or move down,
Do not result in skew, it is to avoid water level monitoring is inaccurate and connects sheet 23 from connecting the problem that through hole 11 skids off.It is subject at float 10
Gravity impact is longitudinally moved down into stopper section 17 and locating part just stops moving down when offseting, and so arranges and makes at water tank wood
The when of having water, the second cylinder 15 of float 10 will not skid off pilot hole.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for the skill of this area
For art personnel, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, that is made any repaiies
Change, equivalent, improvement etc., should be included within the scope of the present invention.
