Filter seat

Abstract

The invention relates to a filter seat. The structure of the filter seat is that an oil inlet cavity and an oil outlet cavity are arranged in a body; the body is provided with differential pressure transducers which are respectively independently communicated with the oil inlet cavity and the oil outlet cavity; and the differential pressure transducers are connected with the input end of an automobile alarm circuit through wires. The differential pressure transducer is a strain type differential pressure transducer, pressure spring type differential pressure transducer or semiconductor type differential pressure transducer. The filter can be used immediately after the filter seat is installed on the filter tank. When an engine works, the change of the differential pressure between the oil inlet cavity and the oil outlet cavity in the filter seat is detected to accurately judge the blocking status of the filter element; and when the filter element is blocked to a certain degree (the differential pressure reaches the specified value), the automobile alarm circuit can immediately give an alarm to remind a user of replacing the filter in time. In other words, it is not necessary to replace the filter according to the working time of the engine or the running mileage of an automobile. As long as the automobile alarm circuit gives an alarm, it indicates that the service life of the filter is over, thereby avoiding the engine damage due to filter element blocking and preventing the engine from being damaged by a poor-quality filter, so that the user can replace the filter in time.

Description

technical field [0001] The invention relates to a filter component, in particular to a filter seat. Background technique [0002] The filter is divided into air filter, fuel filter and engine oil filter. Each type of filter should be equipped with a filter seat on the filter tank. The oil chamber and the oil outlet chamber are provided with a filter element in the filter tank, and a bypass valve is also installed in the filter tank of the oil filter. [0003] When the engine is working, when the filter elements in the air filter and fuel filter are blocked, the engine will be underpowered or stop working; when the filter element in the oil filter is blocked, the unfiltered oil will pass through directly without passing through the filter element. The bypass valve in the oil filter enters the engine, which seriously affects the life of the engine. [0004] After the filter element is blocked, the filter should be replaced in time. Generally, according to the experience of t...

Problems solved by technology

[0003] When the engine is working, when the filter elements in the air filter and fuel filter are blocked, the engine will be underpowered or stop working; when the filter element in the oil filter is blocked, the unfiltered oil will pass through directly without passing through the filter element. The bypass valve in the oil filter enters the engine, which seriously affects the life of the engine

[0004] After the filter element is blocked, the filter should be replaced in time. Generally, according to the experience of the manufacturer, it is stipulated that the engine should be replaced after a certain period of time or the car has traveled a certain number of kilometers. 1. In the case of high oil pollution, the engine often does not work for the specified time or the car does not drive to the specified mileage before the filter element in the filter is blocked (at this time, the user often does not know it)

[0005] In addition, sometimes the filter element is not blocked, and the filter is replaced in advance, resulting in a large waste

[0006] To sum up, the majority of users have no way of knowing exactly when to replace the filter, in other words, it is difficult to replace the filter in a timely manner
