[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1-4 The filter device shown includes a head cover 1 and a filter element assembly 2. The head cover 1 has a through-hole 11, which is filled with an adhesive layer 3. The adhesive layer 3 is made of resin adhesive, which solidifies after filling to form the adhesive layer 3. To increase the adhesion of the adhesive layer, such as... Figure 2 As shown, this utility model has a rough surface 111 on the inner wall of the hole 11. After the adhesive layer 3 fills the rough surface 111 section, it is tightly engaged with the rough surface 111. This can prevent the adhesive layer 3 from abnormally falling off the cylinder head cover 1. Figure 2As shown, the upper section of filter element assembly 2 is solidified and connected within the adhesive layer 3. Filter element assembly 2 is fixed to the head cover 1 via the adhesive layer 3. The lower section of filter element assembly 2 extends beyond the head cover 1 and is immersed in the oil to achieve a filtering effect. Unlike filter elements in conventional filtration devices, the filter element assembly 2 of this invention adopts a special structural design, such as... Figure 2 As shown, the filter element assembly 2 of this utility model includes a plurality of filter filaments 21, such as... Figure 3 As shown, each filter filament 21 is bent into a U-shape, and all the U-shaped filter filaments 21 form a filter element assembly 2, as shown. Figure 4 As shown, the filter wire 21 is hollow inside, with open ends. A filter element assembly 2 is solidified and connected to the adhesive layer 3 in sections, with the filter wire 21's ends solidified and connected to the adhesive layer 3. The filter wire 21 of this invention is made of polypropylene material, and each filter wire 21 has capillary micropores on its surface. The diameter of the capillary micropores on the surface of the filter wire 21 is set to 0.18 micrometers (the diameter of the filter wire 21 is set to 1-2 millimeters in this company). The filter element assembly 2 forms a filtration effect through the capillary micropores on the surface of each filter wire 21. The 0.18-micrometer capillary micropores can block particulate impurities in the oil, allowing high-quality oil to enter the interior of the filter wire 21, while particulate impurities are blocked on the outside of the filter wire 21. This achieves a high-quality filtration effect for the oil. After filtration, the oil that enters the filter wire 21 finally flows out and is collected from the open ends of the filter wire 21. The filter element assembly of this invention has high filtration quality. Advantages: It can well meet the production needs of high-quality recycled oil. The initial filling state of the adhesive layer 3 of this utility model is non-solidified. During manufacturing, the upper part of the filter element assembly 2 is first inserted into the inner hole 11 of the cap 1, and then non-solidified resin glue is filled in. After the resin glue solidifies to form the adhesive layer 3, the filter element assembly 2 is fixed to the adhesive layer 3. During the filling process, the ends of the filter wires 21 may be blocked by glue, which will affect the number of filter wires 21 that can form an effective passage. In this regard, this utility model can reserve a height margin for the cap 1. After the solidified adhesive layer is formed, the top of the cap 1 is trimmed to make up the reserved amount. After trimming, the ends of all filter wires 21 are partially cut off, which will definitely form an opening to facilitate the smooth output of filtered oil. The top of the cap 1 after machining has a light yellow part, which is the adhesive layer 3. The white dense dots in the middle of the adhesive layer 3 are the ends of the filter wires 21.

[0022] like Figure 2 As shown, a sealing groove 12 is provided on the upper and lower end faces of the cylinder head cover 1. A flange 13 protrudes from the outer wall of the cylinder head cover 1, and a sealing groove 12 is also provided on the outer wall of the flange 13. A rubber sealing ring can be installed in the sealing groove 12, so that a sealing effect can be formed on the top, bottom and sides after the filter device of this utility model is installed.

[0023] The filter element assembly 2 of this utility model consists of a filter wire 21. When immersed in oil, the filter wire 21 may spread out, causing it to bend. Some severely bent filter wires 21 can block the internal channels (bending points). Therefore, this utility model designs a mesh cover 4 fitted on the outside of the filter element assembly 2. The mesh cover 4 has relatively large openings, which do not affect the flow of oil, but can restrain the filter wire 21, keeping it in a normal U-shaped state. Figure 2 As shown, the mesh cover 4 is fitted onto the outside of the filter element assembly 2 during initial installation, and the mesh cover 4 and the filter element assembly 2 are solidified together in the adhesive layer 3.

[0024] This utility model has fewer structural components and has the advantages of being simple and convenient to manufacture. When using this utility model, it is immersed in oil. The particulate impurities in the oil are blocked on the outside of the filter wire 21, and the high-quality oil penetrates into the filter wire 21. Under the negative pressure suction, it is output from the open end of the filter wire 21, thus forming a high-quality filtration effect for waste oil.

[0025] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
