Abstract
Water level sensor, including exploring electrode, shell and encapsulation casing, the exploring electrode is installed on the shell, with the shell mould plastics integrative, shell and the encapsulation casing an organic whole of moulding plastics, have on the shell with filter complex external screw thread, open encapsulation casing bottom has the toper groove, the toper marge is around the shell, and the toper inslot has a seal gasket, seal gasket go up to open and to have the electrode hole that supplies the exploring electrode to pass. The utility model discloses a water level sensor is in the clearance peripheral hardware toper groove of once moulding plastics and the secondary is moulded plastics to played sealed effect with seal gasket embedding toper inslot, prevent that water in the filter from getting into water level sensor through this clearance in, play protection water level sensor's effect.
Description
Technical field
The utility model relates to automobile fuel oil filter band oil and water seperator field, specifically a kind of level sensor for diesel-oil filter.
Background technique
Diesel-oil filter level sensor is the water level detected in diesel-oil filter.When the exploring electrode of the ponding height arrival level sensor of filter cleaner, sensor starts to report to the police, and automobile ECU provides an instruction and notifies that driver bleeds off the water in filter cleaner.Level sensor probe puts in the water accumulating cup of filter cleaner by helical thread portion, the shell main material of level sensor is nylon and glass, exploring electrode is made by copper product, they form one by injection moulding, then the packing casing part composition one of quadric injection mould ability and outer ring is carried out, defect is after quadric injection mould, gap is had between the material of an injection moulding and the material of quadric injection mould, although inside is marked with epoxy sealing glue in sensor production process, owing to there being certain pressure in filter cleaner, if Individual gaps is a little large, water sometimes in filter cleaner still can enter level sensor inside by this gap and cause internal short circuits, thus damage level sensor.
Model utility content
The purpose of this utility model is to provide and overcomes the deficiencies in the prior art, provides a kind of level sensor, and this level sensor is used on diesel-oil filter, can prevent the water in filter cleaner from entering level sensor inside.
For solving the problems of the technologies described above, the utility model provides a kind of level sensor, comprise exploring electrode, shell and packing casing, exploring electrode is arranged on shell, is injection molded into one with shell, shell and packing casing are injection molded into one, described shell has the outside thread coordinated with filter cleaner, have cone tank bottom packing casing, described cone tank is around shell, in cone tank, there is gasket seal, described gasket seal has the electrode hole passed for exploring electrode.
Level sensor of the present utility model arranges cone tank in the periphery, gap of an injection moulding and quadric injection mould; and the gasket seal installed with two electrode holes seals; gasket seal embeds in cone tank tightly and serves sealing effect; prevent the water in filter cleaner from entering in level sensor by this gap, play the effect of protection level sensor.
The cross section of described cone tank is quadrilateral.
Accompanying drawing explanation
Fig. 1 is the plan view of the utility model level sensor.
Fig. 2 is the worm's eye view of the utility model level sensor.
Embodiment
Below by the drawings and specific embodiments, model utility is described further.Embodiment described herein only to explain model utility, and is not used in restriction protection domain of the present utility model.
Level sensor, as shown in Figure 1 and Figure 2, comprise exploring electrode 1, shell 2 and packing casing 3, exploring electrode 1 is arranged on shell 2, one is injection molded into shell 2, described shell 2 has the outside thread 21 coordinated with filter cleaner, shell 2 and packing casing 3 are injection molded into one, cone tank is had bottom packing casing 3, the cross section of cone tank is quadrilateral, and described cone tank, around shell 2, has gasket seal 4 in cone tank, gasket seal 4, also in quadrilateral, described gasket seal 4 has the electrode hole 41 passed for exploring electrode 1.
