Technical field
The present invention relates to liquid level sensor, particularly relate to a kind of liquid level sensor with good waterproofing effect.
Background technology
Liquid level sensor is a kind of pressure sensor measuring liquid level, mainly has float-type liquid level sensor, floating ball type liquid level sensor and static pressure type liquid level sensor.Floating ball type liquid level sensor is mainly made up of parts such as ball float, magnet and tongue tubes, and this kind of liquid level sensor is to utilize ball float with liquid level synchronization change, ball float band moving magnet displacement, is controlled the switch of tongue tube further by the displacement of magnet.Existing floating ball type liquid level sensor is due in water tank to be placed into, usually using the cavity to accommodating tongue tube for the sealing gasket to carry out water-proofing treatment, but the time one being long, the air inside cavity can aoxidize the pin of tongue tube, make whole product lose function, reduce its service life.
Content of the invention
The problems referred to above existing for prior art, it is an object of the invention to provide a kind of liquid level sensor with good waterproofing effect and length in service life.
For achieving the above object, the present invention adopts the following technical scheme that the liquid level sensor with good waterproofing effect, including the body of rod, magnetic floating block and control terminal；The described body of rod is the cylindrical structural with hollow cavity, and the bottom of the body of rod is provided with spacing back-up ring, and the top of the body of rod is provided with limit mounting structure；Described limit mounting structure includes the installation portion of horizontally set and vertically arranged limiting section；Described installation portion is provided with installing hole；Being provided with tongue tube in described hollow cavity, described tongue tube is connected with the control terminal being positioned at outside the body of rod by wire, and in described hollow cavity, remaining space is filled with waterproof and sealing material；Scribble corrosion-resistant outside described wire, and the diaphragm of insulation；Described magnetic floating block can be set in outside the body of rod relatively slidably, and is positioned at the part between body of rod upper limit back-up ring and limit mounting structure.
As optimization, being arranged with PVC sleeve pipe outside described wire, the bottom of PVC sleeve pipe abuts with the top of the body of rod, and the top of PVC sleeve pipe abuts with the ligament being connected to outside wire.
As optimization, described magnetic floating block uses corrosion resistant plastic material to make, and inside is provided with magnetisable material.
As optimization, as optimization, described magnetisable material is magnet.
Relative to prior art, present invention have the advantage that the liquid level sensor with good waterproofing effect that the present invention provides is filled with the remaining space of the hollow cavity equipped with tongue tube by waterproof and sealing material, thus reach good waterproof effect, also effectively prevent the pin of air oxidation tongue tube inside hollow cavity simultaneously, extend the service life of tongue tube.
Brief description
Fig. 1 is the sectional view of the liquid level sensor with good waterproofing effect.
In figure, the body of rod the 10th, spacing back-up ring the 11st, installation portion 12a, limiting section 12b, installing hole 12c, tongue tube the 13rd, wire the 14th, PVC sleeve pipe 14a, ligament 14b；The 20th, magnetic floating block controls terminal 30.
Detailed description of the invention
Below in conjunction with the accompanying drawings the present invention is described in further detail.
In describing the invention, it will be appreciated that, the orientation of the instruction such as term " interior ", " outward ", " top ", " low " or position relationship are for based on orientation shown in the drawings or position relationship, it is for only for ease of the description present invention and simplify description, rather than instruction or hint indication device or element must have specific orientation, with specific azimuth configuration and operation, be therefore not considered as limiting the invention.
See Fig. 1, there is the liquid level sensor of good waterproofing effect, including the body of rod the 10th, magnetic floating block 20 and control terminal 30.
The body of rod 10 is the cylindrical structural with hollow cavity, the bottom of the body of rod 10 is provided with spacing back-up ring 11, the top of the body of rod 10 is provided with limit mounting structure, limit mounting structure includes the installation portion 12a and vertically arranged limiting section 12b of horizontally set, installation portion 12a is provided with installing hole 12c, and convenient installation liquid level sensor, when being embodied as, limit mounting structure can be one-body molded with the body of rod, convenient processing and installation.Spacing back-up ring and the setting of limit mounting structure, effectively limit the working range of liquid level sensor, places magnetic floating block and departs from the body of rod.
It is provided with tongue tube 13 in hollow cavity, tongue tube 13 is connected with the control terminal 30 being positioned at outside the body of rod 10 by wire 14, in hollow cavity, remaining space is filled with waterproof and sealing material, reach waterproof effect, also effectively prevent the pin of air oxidation tongue tube inside cavity simultaneously, extend the service life of tongue tube.
Magnetic floating block 20 can be set in outside the body of rod 10 relatively slidably, and is positioned at the part between the body of rod 10 upper limit back-up ring 11 and limit mounting structure.Magnetic floating block 20 uses corrosion resistant plastic material to make, and inside is provided with magnetisable material, and magnetisable material is preferably magnet.
As optimization, scribble corrosion-resistant outside wire 14, and the diaphragm of insulation, effectively protection wire.Being arranged with PVC sleeve pipe 14a outside wire 14, can effectively protecting wire further, the bottom of PVC sleeve pipe 14a abuts with the top of the body of rod 10, and the top of PVC sleeve pipe 14a abuts with the ligament 14b being connected to outside wire 14, thus reaches spacing purpose.
The operation principle of the liquid level sensor with good waterproofing effect that the present invention provides:
Whole liquid level sensor is suspended in the container of liquid level to be measured, magnetic floating block fully penetrates in liquid, the buoyancy that magnetic floating block is subject in liquid changes, thus move on the body of rod, owing to the change of magnetic induction intensity causes the switch activity of tongue tube in its moving process, tongue tube activity produce the signal of telecommunication by wire transmission to control terminal, such that it is able in judging container liquid level change.
Finally illustrate is, above example is only in order to illustrate technical scheme and unrestricted, although the present invention being described in detail with reference to preferred embodiment, it will be understood by those within the art that, technical scheme can be modified or equivalent, without deviating from objective and the scope of technical solution of the present invention, it all should be covered in the middle of scope of the presently claimed invention.
