Liquid filter assembly having a drain pin with a grip

Abstract

The invention relates to a liquid filter module, particulary to an oil filter module or a fuel filter module, comprising a housing with a cylindrical drain nipple on the lower part thereof to drain oil therefrom, a filter accommodated inside of the housing, and a drain pin inserted into the drain nipple, wherein the drain pin comprises a body, a grip including a part at least protruded outwards from the wall of the drain nipple, and a seal member sealing the housing such that the liquid inside does not leak out of the housing when the drain pin is inserted into the drain nipple. By using thisinvention, the operator can prevent contaminations from the liquid leaked from the housing when the operator draws the drain pin out of the housing.

Description

[0001] This application is a divisional application of the invention with the application number "201680073784.8" and the title of the invention "Liquid filter assembly with discharge pin with handle". technical field [0002] The present invention relates to a liquid filter module for filtering liquid, more particularly, to a liquid filter module for filtering engine oil of a vehicle, and more particularly, to a rotatable drain pin for draining engine oil The oil filter module is ground coupled to the filter. Background technique [0003] The following description generally refers to oil filters and their use in motor vehicles, although it is of course obvious that the liquid filter according to the invention can also be used to filter other liquids such as fuel, so that the following discussion also follows in a similar manner Used in liquid filters, especially fuel filters. This means that although the description refers to an oil filter module, the liquid filter module ...

Problems solved by technology

However, when a drain bolt for draining engine fluid (especially oil or fuel) is screwed to the drain hole as in the liquid filter module (especially oil or fuel filter module) according to the prior art, because in When the drain bolt is separated, the internal fluid (especially oil or fuel) flows downward, so the drain bolt, work tools and workers' hands may be contaminated with oil and thus contaminated

In addition, during this process, the oil may be splashed on the work site and pollute the surrounding environment
