Abstract

The utility model relates to a filter on a motor, which solves the problem of providing a new filter which can detect the pressure of an oil inlet chamber and can judge the blocking condition of filter paper. The utility model is characterized in that one side of an oil inlet of the filter is provided with a sensor hole, a pressure sensor is arranged in the sensor hole; the pressure sensor is connected with the input terminal of an alarm circuit by a conducting wire. The utility model judges the blocking condition of filter paper by detecting the pressure variation of an oil inlet chamber; when the filter paper is blocked to a certain extent, alarm is sent out to an electrical system of an automobile, and the user is reminded to replace the filter in time; simultaneously, convenience is brought to the motor maintenance and the waste of unnecessary filter core replacement is avoided.

Description

Novel cleaner

Technical field

The utility model relates to cleaner, relates in particular to air filter, fuel filter and oil filter on the engine.

Background technology

When engine operation; behind air filter and fuel filter obstruction; engine promptly quits work, and oil filter is then different, in engine running; for protecting engine not impaired; must guarantee the sufficient lubrication of machine oil, therefore traditional cleaner under the situation that filter paper blocks, by overflow valve without filter paper; directly unfiltered machine oil is sent into engine, very big to the life-span influence of engine like this.The filter tank of oil filter is a consumable accessory, usually after blocking, filter paper needs in time to change, under normal conditions, do not know when change, generally rule of thumb by producer, the regulation engine is promptly changed at the work certain hour or behind the certain milimeter number of running car, so just there is certain hidden danger, under the big situation of engine running-in period or oil pollution degree, engine is not worked before certain hour or automobile do not drive to certain milimeter number, cleaner blocks, and is bigger to the engine infringement like this, has a strong impact on the life-span of engine; In addition, just be not replaced when filter paper also blocks sometimes, cause certain waste yet.

Summary of the invention

The purpose of this utility model is: a kind of novel cleaner that detects oil suction chamber pressure, judges the filter paper clogged conditions is provided.

Concrete architecture advances scheme is as follows:

Novel cleaner, comprise filter tank, filter paper core, filter block, oil-in and oil-out, it is characterized in that: oil-in one side at cleaner has a gauge hole, is provided with pressure sensor in the gauge hole, and pressure sensor is connecting the input of auto alarm circuit by lead.

Novel cleaner according to above-mentioned is characterized in that: described pressure sensor is the piezo-electric crystal pressure sensor, is strain pressure transducer, is diaphragm type pressure sensor, is the compressed spring type pressure sensor, is the semiconductor-type pressure sensor.

Useful technique effect of the present utility model embodies both ways:

1, setting pressure sensor on the oil-in of cleaner, by detecting the variation of oil suction chamber pressure, judge the clogged conditions of filter paper, when filter paper is clogged to a certain degree, send warning to automotive electrical system, remind the user in time to change cleaner, prevent because of the infringement of clogged filter to engine; Also can prevent simultaneously of the harm of fake and forged oil filter to engine.

2, the utility model with traditional cleaner principle and modern sensor technological incorporation together, improve under the little situation at production cost, the performance of product is significantly improved, there is significance in life-span to the raising engine, bring convenience for simultaneously the maintenance of engine, avoid unnecessary waste.

Description of drawings

Fig. 1 is the utility model structural representation.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is further described by embodiment.
