Description

Technical Field

[0001] The utility model belongs to the technical field of filter elements, and in particular relates to a large-flow filter element with a snap-on installation structure. Background Art

[0002] The filter element can block solid particles, bacteria, viruses, metal ions and other impurities in the fluid, allowing clean fluid to flow out through the filter element, so the filter element can be used in filtration industries such as oil filtration, air filtration, and water filtration.

[0003] For example, a large-flow filter element with a new handle with publication number "CN207324266U" includes a filter element body, which is divided into a handle, an end cover, a filter material, an outer shell and a bottom cover. The end cover, the filter material, the outer shell and the bottom cover are connected together by hot-melt welding. A clip is provided on the end cover, and the clip and the end cover are plastic parts that are injection-molded in one step. A block is provided on the handle, and the block and the handle are plastic parts that are injection-molded in one step. The end cover and the handle are tightly assembled and connected together by the clip and the block. The beneficial effects of the utility model are simple in structure and tight in assembly. The end cover is connected to the outer shell, the filter material and the bottom cover by hot-melt welding. The end cover and the handle are separately injection-molded and then assembled, which avoids leakage problems caused by gaps due to the ellipticity existing after injection molding due to the crossbeam structure of the handle, thereby ensuring product quality.

[0004] The inventor believes that the handle on the above-mentioned large-flow filter element is installed on the end cover through a snap-on and snap-on connection, so the large-flow filter element is a large-flow filter element with a snap-on installation structure. However, when the large-flow filter element is in use, the filter material is installed inside the shell by hot-melt welding. In this way, when the filter material is not effective and needs to be replaced, the filter material cannot be replaced alone, and the large-flow filter element needs to be replaced as a whole. This makes the shell part unusable, thereby increasing the maintenance cost of the large-flow filter element and causing inconvenience to the operator.

[0005] Therefore, the utility model provides a large flow filter element with a snap-on installation structure to solve the above problems. Utility Model Content

[0006] The purpose of the present utility model is to provide a large-flow filter element with a snap-on mounting structure, aiming to solve the problem in the prior art that the filter material is installed inside the shell by hot-melt welding. When replacement is needed, the filter material cannot be replaced individually and the large-flow filter element needs to be replaced as a whole, which makes the shell part unusable, thereby increasing the maintenance cost of the large-flow filter element.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a large-flow filter element with a snap-on mounting structure, comprising a shell, the bottom surface of the shell being connected to a bottom cover, the inner bottom surface of the bottom cover being connected to a limiting column, one end of the limiting column extending into the interior of one end of the filter material, the top surface of the shell being connected to a connecting block, the outer surface of the connecting block being provided with a surface thread, the outer surface of the surface thread being connected to a thread groove, the thread groove being provided on the inner surface at the bottom end of the end cover, the inner surface of the top end of the end cover being connected to a sealing ring, one end of the sealing ring extending into the card slot, the card slot being provided on the outer surface of the top end of the connecting block, the inner top surface of the end cover being connected to a limiting ring, the inner surface of the limiting ring being connected to the outer surface of one end of the filter material, the top surface of the end cover being provided with a through hole, and the inner surface of the shell being further provided with a limiting mechanism.

[0008] In order to ensure that the filter material can slide vertically downward, as a preferred large-flow filter element with a snap-on mounting structure of the utility model, the limiting mechanism includes: a limiting block, a through groove and a rubber ring. The inner surface of the outer shell is connected to the limiting block, and a through groove is provided on the top surface of the limiting block. The inner surface of the through groove is connected to a rubber ring, and the inner surface of the rubber ring is in contact with the outer surface of the filter material.

[0009] In order to enable the limiting post to be inserted into the interior of the filter material, as a preferred embodiment of the present invention, a large flow filter element with a snap-on mounting structure is provided, wherein a sliding connection is formed between the filter material and the limiting post.

[0010] In order to realize the disassembly and assembly of the end cover and improve the sealing between the end cover and the connecting block, a large flow filter element with a snap-on mounting structure is preferably used in the present invention. The end cover is threadedly connected with the surface thread through the thread groove, and the sealing ring is snap-fitted with the connecting block through the snap-on structure.

[0011] In order to enable the filter material to be inserted into the interior of the limiting ring and the through hole to be connected to the interior of the filter material, a large-flow filter element with a snap-on mounting structure is preferably used in the present invention. A sliding connection is formed between the limiting ring and the filter material, and the position and size of the through hole match the position and size of the internal space of the filter material.

[0012] In order to limit the movement trajectory of the filter material, as a preferred embodiment of the present invention, a large-flow filter element with a snap-on mounting structure is provided, wherein three groups of limit blocks are distributed in a longitudinal array on the inner surface of the shell, and a sliding connection is formed between the rubber ring and the filter material.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] The utility model sets the end cover to be detachable. When the filter material needs to be replaced, the end cover only needs to be twisted to separate the end cover from the connecting block through the threaded groove. At this time, the limit ring on the end cover will also slide out of the filter material. At this time, the operator can separate the filter material from the shell by pulling the filter material upward, so that the operator can maintain and replace the filter material separately, avoiding the operator from replacing the entire large-flow filter element, thereby reducing the maintenance cost of the large-flow filter element.

[0015] The utility model provides a limiting mechanism. When the filter material is placed inside the shell, the limiting block and the rubber ring can allow the filter material to slide downward inside the rubber ring, ensuring that the filter material moves vertically downward, so that the filter material can be accurately placed inside the shell, which brings convenience to the installation of the filter material.

[0024] By sliding the filter material 4 into the housing 1, the filter material 4 is moved downward along the rubber ring 15 in the housing 1, so that the limiting column 3 on the bottom cover 2 will slide and be inserted into the bottom of the filter material 4, so that the bottom end of the filter material 4 is restricted. At this time, the end cover 8 is screwed into the surface thread 6 on the connecting block 5 through the thread groove 7, so that the position of the end cover 8 can be fixed on the connecting block 5. At the same time, the sealing ring 9 provided on the inner side of the end cover 8 will also move and be engaged into the card groove 10 on the connecting block 5, thereby increasing the sealing between the end cover 8 and the connecting block 5. When the end cover 8 is installed, the limiting ring 11 provided at the bottom of the end cover 8 will also move downward, allowing the top of the filter material 4 to extend into the limiting ring 1 1, the limit column 3 and the limit ring 11 set in this way can fix the position of the filter material 4 in the housing 1, and when the handle on the end cover 8 needs to be installed, it is only necessary to slide the buckles at both ends of the handle into the blocks on the end cover 8, so that the handle can be snap-fitted to the end cover 8, thereby realizing the snap-fit ​​installation operation of the handle, thereby completing the assembly operation of the large-flow filter element, so that the large-flow filter element can be installed and used. A sealing gasket can be provided between the end cover 8 on the inner side of the limit ring 11 and the filter material 4, thereby increasing the sealing between the end cover 8 and the limit ring 11 and the filter material 4, and avoiding the occurrence of gaps between the filter material 4 and the limit ring 11, which may cause leakage of unfiltered fluid.

[0025] Preferably, the limiting mechanism includes: a limiting block 13, a through groove 14 and a rubber ring 15. The inner surface of the shell 1 is connected to the limiting block 13. The top surface of the limiting block 13 is provided with a through groove 14. The inner surface of the through groove 14 is connected to the rubber ring 15. The inner surface of the rubber ring 15 contacts the outer surface of the filter material 4.

[0026] During specific use, the filter material 4 is slid into the outer shell 1, and the filter material 4 is allowed to move downward along the rubber ring 15 on the limit block 13 in the outer shell 1 to ensure the vertical movement trajectory of the filter material 4. The limit column 3 on the bottom cover 2 will accurately slide and insert into the bottom of the filter material 4, so that the bottom end of the filter material 4 is restricted, thereby facilitating the installation of the filter material 4 and avoiding the filter material 4 from being skewed during the placement process.

[0027] Preferably, a sliding connection is formed between the filter material 4 and the limiting column 3 .

[0028] During specific use, when the filter material 4 slides downward, the limiting post 3 can be slidably inserted into the interior of the bottom end of the filter material 4 , so that the limiting post 3 limits the bottom position of the filter material 4 .

[0029] Preferably, the end cover 8 is threadedly connected to the surface thread 6 via the thread groove 7 , and the sealing ring 9 is engaged with the connecting block 5 via the clamping groove 10 .

[0030] During specific use, the end cover 8 can be screwed onto the surface thread 6 on the outer surface of the connecting block 5 through the thread groove 7, so that the end cover 8 is fixedly installed on the connecting block 5. At this time, the sealing ring 9 on the inside of the end cover 8 will also move to the card groove 10, allowing the sealing ring 9 to be elastically engaged in the card groove 10, thereby increasing the sealing between the end cover 8 and the connecting block 5.

[0031] Preferably, the limiting ring 11 and the filter material 4 form a sliding connection, and the position and size of the through hole 12 match the position and size of the internal space of the filter material 4 .

[0032] During specific use, after the end cover 8 is installed on the connecting block 5, one end of the filter material 4 will also slide and be inserted into the limiting ring 11, so that the limiting ring 11 limits the top of the filter material 4. At this time, the through hole 12 on the end cover 8 will be connected to the internal space of the filter material 4.

[0033] Preferably, three groups of limit blocks 13 are distributed in a longitudinal array on the inner surface of the housing 1 , and a sliding connection is formed between the rubber ring 15 and the filter material 4 .

[0034] During specific use, three groups of limit blocks 13 are provided on the inner side of the housing 1 , so that when the filter material 4 slides downward, it will move downward along the penetrating rubber ring 15 .

[0035] Working principle: When using the large flow filter element with a snap-on installation structure, when the filter material 4 inside the housing 1 is not performing well and needs maintenance and replacement, just twist the end cap 8 to separate the surface thread 6 on the connecting block 5 through the thread groove 7. In this way, the end cap 8 will drive the limit ring 11 to move upward, so that the limit ring 11 is separated from the filter material 4. At this time, the filter material 4 in the housing 1 will be exposed. At this time, the filter material 4 can be pulled out of the housing 1 by sliding, so that the operator can perform filter operations on the filter material 4 separately. Maintenance and replacement can be carried out to avoid the operator replacing the overall large-flow filter element, thereby reducing the maintenance cost of the large-flow filter element. Secondly, when the filter material 4 is placed and installed, the filter material 4 is slid into the shell 1, and the filter material 4 is allowed to move downward along the rubber ring 15 on the limit block 13 in the shell 1 to ensure the vertical movement trajectory of the filter material 4. The limit column 3 on the bottom cover 2 will accurately slide and insert into the bottom of the filter material 4, so that the bottom end of the filter material 4 is restricted, thereby bringing convenience to the installation of the filter material 4 and avoiding the filter material 4 from being easily skewed during the placement process.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
