Description

Technical Field

[0001] The utility model relates to the technical field of filter element end covers, in particular to an end cover for a filter element. Background Art

[0002] Filter elements are mostly used for filtering, and the filter elements include end covers, which are mainly used to filter the filter material inside the filter element, thereby keeping the filter element clean and running effectively, and at the same time play a role in supporting the filter material. Existing filter element end covers are usually made of steel plates, plastics, polyurethane and other materials. A rubber strip is usually provided between the filter element end cover and the filter element assembly to increase the sealing performance of the filter element end cover and the filter element assembly. The existing rubber strip is usually provided on the side of the filter element end cover facing the filter element assembly, and is bonded to the filter element end cover by using adhesive. The filter element end cover produced in this way has poor performance. After the filter element end cover and the filter element assembly are covered, there is some gap between the rubber strip and the filter element end cover, which will reduce the sealing performance of the filter element assembly, so it needs to be improved. Utility Model Content

[0003] The main purpose of the utility model is to provide an end cover for a filter element, aiming to provide an end cover for a filter element with good performance.

[0004] To achieve the above purpose, the utility model proposes an end cover for a filter element, including a cover body and an elastic strip, the elastic strip is arranged on one side of the cover body, the connection between the elastic strip and the cover body is coated with elastic sealant to form an arc-shaped sealing surface at the connection between the elastic strip and the cover body.

[0005] Specifically, the elastic strip is fixed to one side of the cover body by adhesive.

[0006] Specifically, the elastic sealant is silicone sealant.

[0007] Specifically, the sealing surface is formed on the inner side and the outer side of the elastic rubber strip, and the curvature directions of the arcs of the sealing surface located on the inner side and the sealing surface located on the outer side are opposite.

[0008] Specifically, the cover body is made of plastic material.

[0009] The technical solution of the utility model is to coat elastic sealant at the connection between the elastic strip and the cover body so that an arc-shaped sealing surface is formed at the connection between the elastic strip and the cover body, thereby improving the connection stability between the elastic strip and the cover body, and at the same time improving the sealing performance of the cover body and the filter element assembly after being covered.

[0014] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, top, bottom, inside, outside, vertical, horizontal, longitudinal, counterclockwise, clockwise, circumferential, radial, axial...), then the directional indication is only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0016] In addition, if there are descriptions involving "first" or "second" etc. in the embodiments of the utility model, the descriptions of "first" or "second" etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0017] like Figures 1 to 3 As shown, an end cap for a filter element includes a cover body 10 and an elastic rubber strip 11. The elastic rubber strip 11 is arranged on one side of the cover body 10. The connection between the elastic rubber strip 11 and the cover body 10 is coated with elastic sealant so that an arc-shaped sealing surface 12 is formed at the connection between the elastic rubber strip 11 and the cover body 10. By coating the elastic sealant at the connection between the elastic rubber strip 11 and the cover body 10, an arc-shaped sealing surface 12 is formed at the connection between the elastic rubber strip 11 and the cover body 10, thereby improving the connection stability between the elastic rubber strip 11 and the cover body 10, and at the same time improving the sealing performance of the cover body 10 and the filter element assembly after being covered.

[0018] The elastic strip 11 is fixed on one side of the cover 10 by adhesive; the elastic sealant is an organic silicone sealant, which is elastic after curing. After curing, the organic silicone sealant does not affect the original characteristics of the elastic strip 11, and can also increase the area of ​​the contact part between the elastic strip 11 and the cover 10 through the organic silicone sealant, thereby improving the sealing effect; the sealing surface 12 is formed on the inner and outer sides of the elastic strip 11, and the arc bending direction of the sealing surface 12 located on the inner side and the sealing surface 12 located on the outer side is opposite; the cover 10 is made of plastic material. In this embodiment, the elastic strip 11 is first bonded and connected to one side of the cover 10 by adhesive, and then a secondary sealing connection is performed by organic silicone sealant. The organic silicone sealant is bonded to the elastic strip 11 and the cover 10 by curing at room temperature to improve the stability of the connection between the elastic strip 11 and the cover 10, and at the same time improve the sealing performance of the cover 10 when in use, and arc-shaped sealing surfaces 12 are formed on both the front and rear sides of the elastic strip 11 to further improve the sealing effect.

[0019] In the actual manufacturing process, the surfaces of the cover body 10 and the elastic strip 11 are smooth without defects such as wrinkles, cracks, burrs, and defects. At the same time, the cover body 10 and the elastic strip 11 are bonded together by silicone sealant, and the bonding should be firm.

[0020] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
