Description

Technical Field

[0001] This utility model relates to the field of filter technology, and in particular to a filter housing with a simplified structure. Background Technology

[0002] A filter is a component that filters impurities, water, and particulate matter from fuel. Because diesel fuel is highly hydrophilic and easily mixes with water, diesel fuel filters are usually equipped with a water collection cup to collect the water in the diesel fuel.

[0003] For diesel filters currently on the market, the connection between the water collection cup and the filter body is generally as follows: the lower end of the filter body is equipped with a plastic cover and a plastic connector, and then the water collection cup is connected through the plastic connector. Glue needs to be applied during assembly. This connection method is relatively cumbersome, involves a large number of parts, and requires a large number of molds for production, so it needs to be improved. Utility Model Content

[0006] The water collection cup connector includes an integrally formed cover plate, a connecting plate, an internal threaded sleeve, and a locking ring, which are distributed vertically. The cylinder is connected to the locking ring through a locking assembly to fix the water collection cup connector in the cylinder. The internal threaded sleeve is used to connect with the water collection cup, and the cover plate is provided with a water passage hole that runs vertically through and communicates with the internal threaded sleeve.

[0007] Preferably, multiple connecting plates are provided, and the connecting plates are distributed at equal angles around the axis of the cover plate. The upper side of the connecting plate is connected to the lower end of the cover plate, and the lower side of the connecting plate is fixed to the upper end face of the internal threaded sleeve.

[0008] Preferably, the lower side of the cover plate is integrally formed with a ring, the inward end of the connecting plate is connected to the outer curved surface of the ring, and the ring is fitted around the water passage hole.

[0009] Preferably, the outer end of the connecting plate is also integrally formed with a vertically arranged vertical rib, which is connected to both the inner threaded sleeve and the outer curved surface of the cover plate.

[0010] Preferably, the upper side of the cover plate is integrally formed with a vertical cylinder, the outer curved surface of the vertical cylinder is coplanar with the outer curved surface of the cover plate, and the vertical rib extends upward to the outer curved surface of the vertical cylinder.

[0028] Reference Figures 1-5 According to an embodiment of a simplified filter housing of the present invention, it includes a cylindrical body 11, wherein an upper end cap 12 and a water collection cup connector 13 are provided inside the cylindrical body 11.

[0029] When this utility model is assembled to form a complete filter, the filter element is placed between the end cap 12 and the water collection cup connector 13, and the water collection cup is connected to the cylinder 11 through the water collection cup connector 13. The end cap 12 is also provided with annularly distributed oil inlet holes and individually distributed oil outlet holes at the axis. When the oil enters the cylinder 11 through the oil inlet holes, it will be filtered by the filter element and discharged through the oil outlet holes. The water in the oil will accumulate in the water collection cup under the influence of gravity and other factors. In addition, the cylinder can also be equipped with a spring and a bypass valve to avoid excessive pressure upstream of the filter element when it is clogged. The working process and internal components of this filter are existing technologies and will not be described in detail here.

[0030] In this embodiment, as Figure 2 As shown, the specific structure of the water collection cup connector 13 is as follows: the water collection cup connector 13 includes a cover plate 21, a connecting plate 22, an internal threaded sleeve 23, and a locking ring 24 that are distributed vertically and integrally formed. The cylinder 11 is connected to the locking ring 24 through a locking assembly, and the water collection cup connector 13 is fixed inside the cylinder 11. The internal threaded sleeve 23 is used to connect with the water collection cup. In order to facilitate the flow of water in the oil in the cylinder 11 to the water collection cup during filtration, the cover plate 21 is provided with a water passage hole that runs vertically through and communicates with the internal threaded sleeve 23.

[0031] The connecting plate 22 is used to connect the cover plate 21 and the internal threaded sleeve 23. Multiple connecting plates 22 are provided, and the connecting plates 22 are distributed at equal angles with the axis of the cover plate 21 as the center. The upper side of the connecting plate 22 is connected to the lower end of the cover plate 21, and the lower side of the connecting plate 22 is fixed to the upper end face of the internal threaded sleeve 23.

[0032] To further increase the connection strength between the cover plate 21 and the internal threaded sleeve 23, a ring 25 is integrally formed on the lower side of the cover plate 21, and the inward end of the connecting plate 22 is connected to the outer curved surface of the ring 25, and the ring 25 is fitted around the water passage hole.

[0033] In addition, in order to increase the connection strength while keeping the water cup connector 13 stable inside the cylinder 11, the outer end of the connecting plate 22 is also integrally formed with a vertically arranged vertical rib 26. The vertical rib 26 is connected to the outer curved surface of the internal thread sleeve 23 and the cover plate 21. The vertical rib 26 can also be attached to the inner wall surface of the cylinder 11. Furthermore, the vertical rib 26 is also connected downward to the upper side of the locking ring 24.

[0034] Furthermore, a vertical cylinder 27 is integrally formed on the upper side of the cover plate 21. The outer curved surface of the vertical cylinder 27 is coplanar with the outer curved surface of the cover plate 21, and the vertical rib 26 extends upward to the outer curved surface of the vertical cylinder 27 to increase the length of the vertical rib 26, making the water cup connector 13 more stable inside the cylinder 11.

[0035] The locking assembly includes a locking section 31 integrally formed on the lower end of the cylinder 11 and inwardly fastened, such as... Figure 4 As shown, the locking segment 31 is fastened to the inner curved surface of the locking ring 24, thereby locking the water cup connector 13 and preventing leakage.

[0036] In addition, two protruding plates 32 are distributed on the left and right sides inside the locking section 31, and the internal threaded sleeve 23 is provided with a notch for accommodating the protruding plates 32. The protruding plates 32 make it difficult for the water cup connector 13 to rotate inside the cylinder 11, thus preventing the water cup connector 13 from rotating when the operator rotates the water cup.

[0037] After the water collection cup is threadedly connected to the internal threaded sleeve 23, it will press against the connecting plate 22. To prevent the connecting plate 22 from deforming, Figure 3 As shown, the connecting plate 22 increases in width and forms a stepped surface after moving away from the ring 25 at a certain distance.

[0038] It should be noted that a sealing ring is built into the water collection cup to prevent leakage, and the installation, locking and sealing methods of the upper cover 12 are also existing technologies, which will not be described in detail here.

[0039] The above description is only a specific embodiment of the present utility model, but the technical features of the present utility model are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present utility model are covered by the patent scope of the present utility model.
