DETAILED DESCRIPTION

[0038] The following is combined with Figure 1-8 This application is described in further detail.

[0039] The embodiment of the present application discloses a filter element with a heating function.

[0040] Example 1: Combination Figure 1 and Figure 2 As shown, it includes an upper end cover 1 and a lower end cover 2, which are coaxially arranged in a circular shape as a whole. A cylindrical filter paper 3 is fixed between the upper end cover 1 and the lower end cover 2. A circular hole for oil drainage is provided at the center of the upper end cover 1. Two ends of the filter paper 3 are respectively bonded and fixed to the upper end cover 1 and the lower end cover 2 by epoxy resin. A central pipe frame is sleeved inside the filter paper 3, and the central pipe frame is used to support the filter paper 3.

[0041] An arc groove 4 is arranged on the side of the upper end cover 1 facing away from the filter paper 3. The arc groove 4 is surrounded by a plate integrally arranged on the upper end cover 1. A sealing cover 5 is provided at the opening of the arc groove 4. After the sealing cover 5 seals the opening of the arc groove 4, the arc groove 4 becomes a sealed space. A circular connecting hole 6 is opened on the sealing cover 5. The connecting hole 6 is used to insert and connect the oil supply pipe. The oil to be filtered is input into the arc groove 4 from the connecting hole 6 through the oil supply pipe. A heating component 7 is arranged in the arc groove 4. The oil input into the arc groove 4 is heated by the heating component 7. A plurality of oil drain holes 8 connected with the arc groove 4 are also arranged on the upper end cover 1. The oil drain holes 8 are arranged at intervals along the circumference of the upper end cover 1. The oil heated by the heating component 7 is discharged from the oil drain hole 8 between the filter paper 3 and the casing. After the hot oil is filtered by the filter paper 3, the clean oil is discharged from the center of the filter paper 3 through the pipeline.

[0042] The sealing cover 5 is provided with a buckle protrusion, and the inner wall of the arc groove 4 is correspondingly provided with a buckle groove. When the sealing cover 5 is covered, the buckle protrusion is embedded in the groove, so that the sealing cover 5 and the arc groove 4 are sealed. For the sake of safety, a sealing gasket can also be provided on the sealing cover 5 for sealing. After the end cover of the filter is installed, the sealing cover 5 can also be pressed, so that the sealing cover 5 is not easy to be separated from the arc groove 4. In order to strengthen the strength of the arc groove 4, a reinforcing rib 21 is provided on the inner wall of the upper end cover 1. The reinforcing rib 21 is distributed on the outer wall of the arc groove 4, which has the effect of reinforcing the plate surrounding the arc groove 4.

[0043] Combination Figure 3 and Figure 4 As shown, the heating assembly 7 includes an upper fixing plate 9 and a lower fixing plate 10, and a circular heating plate 11 is sandwiched between the upper fixing plate 9 and the lower fixing plate 10. The upper fixing plate 9, the heating plate 11 and the lower fixing plate 10 can conduct heat and electricity. The upper fixing plate 9 and the lower fixing plate 10 are both in an arc shape that fits the arc groove 4 as a whole, and an extension plate 25 ( Figure 2 As can be seen in the figure, the extension piece 25 extends outside the arc groove 4 and is connected to the electricity, so that the heating piece 11 is energized and heated, and the upper fixing piece 9 and the lower fixing piece 10 also heat up.

[0044] A lower space 13 is formed between the lower fixing plate and the arc groove 4, and the oil drain hole 8 is connected to the lower space 13. A middle space 12 is formed between the upper fixing plate 9 and the lower fixing plate 10 in cooperation with the arc groove 4. The upper fixing plate 9 and the arc groove 4 cooperate with the sealing cover 5 to form an upper space 14, and the connecting hole 6 on the sealing cover 5 is located at one end of the arc groove 4. The upper space 14 is connected to the middle space 12 at the end away from the connecting hole 6, that is, a notch is set at the end of the upper fixing plate 9 away from the connecting hole 6, and the middle space 12 is connected to the lower space 13 at the end close to the connecting hole 6, that is, a notch is set at the end of the lower fixing plate 10 close to the connecting hole 6, so that the engine oil input at the connecting hole 6 flows along an "S"-shaped trajectory, and then is discharged from the lower space 13 to between the filter paper 3 and the casing through the oil drain hole 8, so as to extend the flow path of the engine oil, so that the engine oil stays in the arc groove 4 longer, so that the engine oil can be fully heated.

[0045] A support block 15 integrally arranged on the upper end cover 1 is provided at the bottom of the arc groove 4, and the lower fixing plate 10 is supported on the support block 15, and a fixing bolt 16 is threadedly connected to the support block 15, and the upper fixing plate 9, the heating plate 11, and the lower fixing plate 10 are fixed to the support block 15 by the fixing bolt 16; a clamping member 17 is also passed through the fixing bolt 16, and the clamping member 17 includes a square main board 18, and elastic clamping plates 19 are integrally arranged on the four sides of the main board 18. The elastic clamping plate 19 is supported on the upper fixing plate 9 and props up the main board 18, so that there is a gap between the main board 18 and the upper fixing plate 9, and a washer 20 is also sleeved on the fixing bolt 16; the fixing bolt 16 passes through the washer 20, the main board 18, the upper fixing plate 9, the heating plate 11 and the lower fixing plate 10 in turn and is threadedly connected to the support block 15, and the upper fixing plate 9 and the lower fixing plate 10 are kept clamped with the heating plate 11 by the action of the elastic clamping plate 19.

[0046] Example 2: Figure 5 As shown, the difference between this embodiment and embodiment 1 is that two step surfaces 22 are further provided on the inner side wall of the arc groove 4, and the edges of the upper fixing plate 9 and the lower fixing plate 10 are respectively attached to and supported on the corresponding step surfaces 22; and a pressing edge 23 is integrally provided on the sealing cover 5, and when the sealing cover 5 is closed, the pressing edge 23 presses the edge of the upper fixing plate 9 on the step surface 22; at the same time, the shape of the heating plate 11 can also be changed so that the heating plate 11 can press the edge of the lower fixing plate 10 on the step surface 22, so that the upper fixing plate 9 and the lower fixing plate 10 can be made thinner, so that the thermal conductivity of the upper fixing plate 9 and the lower fixing plate 10 is better.

[0047] Example 3: Figure 6 As shown, the difference between this embodiment and embodiment 1 is that each oil drain hole 8 is arranged obliquely downward at one end away from the lower space 13, so that the oil discharged from the oil drain hole 8 rushes obliquely to the casing instead of violently impacting the casing head-on.

[0048] Example 4: Figure 7 As shown, the difference between this embodiment and embodiment 1 is that a wedge-shaped undercut 24 is also integrally provided at the end of each reinforcing rib 21. When the sealing cover 5 is closed, the undercut 24 can press the sealing cover 5 and cooperate with the end cover of the filter to make it difficult for the sealing cover 5 to detach from the arc groove 4, so that the sealing cover 5 and the arc groove 4 are kept sealed.

[0049] Example 5: Figure 8 As shown, the difference between this embodiment and embodiment 1 is that the shape of the support block 15 is changed, and some of the support blocks 15 are spliced ​​together so that the lower space 13 forms a curved passage. After the engine oil enters the lower space 13, it first flows from the inner side of the lower space 13, then turns and flows to the outer side of the lower space 13, and is discharged from the oil drain hole 8.

[0050] This specific embodiment is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make modifications to the present embodiment without any creative contribution as needed, but such modifications are protected by the patent law as long as they are within the scope of the claims of the present application.
