Description

Technical Field

[0001] The present application relates to the field of fuel filter elements, and in particular to a fuel filter element that is easy to assemble and disassemble. Background Art

[0002] The fuel filter is an accessory installed in the car to filter the car's fuel. The fuel passes through the filter and enters the car engine. The filter can filter out solid impurities in the fuel, thereby reducing the damage of solid impurities to the engine and increasing the engine's service life.

[0003] The filter consists of a housing and a filter element. The filter element is removably attached to the housing. The housing is a closed shell with an inlet and outlet pipes, through which fuel can flow within the housing. The filter element consists of an inner cylinder and filter paper. The inner cylinder is cylindrical, and the filter paper is also cylindrical. The filter paper is placed outside the inner cylinder. Fuel flows through the filter paper, and solid impurities in the fuel accumulate on one side of the filter paper. If impurities accumulate on one side of the filter paper, the user can replace the filter element to maintain optimal filtering performance.

[0004] The above-mentioned related technical solutions have the following defects: the surface of the inner cylinder of the filter element is smooth and the filter paper is soft, making it difficult for users to pull the filter element out of the casing, and replacing the filter element is time-consuming and laborious. Utility Model Content

[0005] In order to facilitate users to replace the filter element, the present application provides a fuel filter element that is easy to disassemble and assemble.

[0006] The present application provides a fuel filter element that is easy to disassemble and assemble, which adopts the following technical solution:

[0007] A fuel filter element that is easy to disassemble and assemble includes a filter element inner cylinder and a clamping piece. The filter element inner cylinder is a cylindrical structure. A boss is provided on the inner wall of the filter element inner cylinder. The boss is coaxially arranged with the filter element inner cylinder. The clamping piece is detachably connected to the end of the filter element inner cylinder. The clamping piece is inserted into the filter element inner cylinder and clamped with the boss.

[0008] By adopting the above technical solution, a boss is set on the inner wall of the inner cylinder of the filter element, so that the outer wall of the inner cylinder of the filter element remains smooth and filter paper can be installed. By detachably connecting the clamping piece on the inner cylinder of the filter element, the clamping piece can be inserted into the inner cylinder of the filter element and engaged with the boss. The user can pull the inner cylinder of the filter element through the clamping piece, thereby pulling the inner cylinder of the filter element out of the casing, making it convenient for the user to replace the filter element.

[0009] Optionally, the clamping member includes a connecting plate, a snap-fit ​​member and a handle. The connecting plate is a circular plate structure. The snap-fit ​​member is connected to one side surface of the connecting plate. The handle is fixed to the other side of the connecting plate. The snap-fit ​​member is used to insert into the inner cylinder of the filter element and snap-fit ​​to the boss.

[0010] By adopting the above technical solution, a clamping piece is set on the connecting plate so that the clamping piece can be inserted into the inner tube of the filter element, and then the clamping piece is clamped with the boss. When the clamping piece is clamped with the boss, the user can pull the handle to make the clamping piece drive the inner tube of the filter element to move, thereby facilitating the extraction and replacement of the filter element.

[0011] Optionally, the clamping part is a cylindrical structure, and a plurality of protrusions are provided on the outer wall of the clamping part. A slope is provided on the lower bottom side of the protrusion, and the slope is used to abut against the boss. A clamping surface is provided on the protrusion, and the clamping surface is provided on the side of the protrusion away from the slope, and the clamping surface is used to abut against the boss.

[0012] By adopting the above technical solution, a protrusion is provided on the clamping part, and a slope is provided on the protrusion so that the slope can abut against the boss. The user pushes the clamping part to automatically deform the clamping part, so that the protrusion can slide from one side of the boss to the other side, and the clamping surface of the protrusion abuts against the boss, so that the inner tube of the filter element and the clamping part remain tightly connected.

[0013] Optionally, a plurality of clearance grooves are provided on the clamping member, and the clearance grooves are arranged at equal intervals along the circumference of the clamping member.

[0014] By adopting the above technical solution, by opening a clearance groove on the clamping part, multiple tooth-shaped structures are formed on the end of the clamping part. When the clamping part is inserted into the inner tube of the filter element and the protrusion abuts against the boss, the clamping part is more easily deformed, thereby allowing the protrusion to slide on the boss.

[0015] Optionally, a chamfer is formed on one end of the clamping member away from the connecting plate.

[0016] By adopting the above technical solution, by providing a chamfer on the clamping piece, the chamfer plays a guiding role, making it easier for users to insert the clamping piece into the inner barrel of the filter element.

[0017] Optionally, a connecting hole is opened in the center of the connecting plate, and the connecting hole passes through the connecting plate.

[0018] By adopting the above technical solution, a connecting hole is provided in the center of the connecting plate. When the clamping piece is inserted into the filter inner cylinder and clamped with the filter inner cylinder, when there is fuel in the filter inner cylinder, the connecting plate cover is arranged on the filter inner cylinder when the clamping piece is inserted into the filter inner cylinder, so that a closed space is formed in the filter inner cylinder. By providing a connecting hole on the connecting plate, the upper and lower sides of the connecting plate are connected. When the connecting plate cover is arranged on the filter inner cylinder, the filter inner cylinder is connected to the outside atmosphere, so that the clamping piece can be conveniently and quickly connected to the filter inner cylinder.

[0019] Optionally, a weight-reducing hole is provided on the handle.

[0020] By adopting the above technical solution and providing a weight-reducing hole on the handle, the overall weight of the clamp is reduced, thereby making it easier to use.

[0021] Optionally, the filter element inner tube and the clamping piece are made of plastic material.

[0022] By adopting the above technical solution and using plastic to make the filter element inner cylinder and the clamping piece, the weight of the filter element inner cylinder and the clamping piece can be reduced. When the filter element inner cylinder and the clamping piece are connected, the connection stability between the filter element inner cylinder and the clamping piece is better, and the probability of the filter element inner cylinder and the clamping piece detaching from each other is lower.

[0023] In summary, the beneficial technical effects of this application are:

[0024] 1. By providing a boss on the inner wall of the filter cartridge inner barrel, the outer wall of the filter cartridge inner barrel remains smooth and can be installed with filter paper. By detachably connecting a clamping piece to the filter cartridge inner barrel, the clamping piece can be inserted into the filter cartridge inner barrel and engaged with the boss. The user can pull the filter cartridge inner barrel out of the housing by the clamping piece, making it convenient for the user to replace the filter cartridge;

[0025] 2. By providing a clamping piece on the connecting plate, the clamping piece can be inserted into the inner tube of the filter element, and then the clamping piece is clamped with the boss. When the clamping piece is clamped with the boss, the user can pull the handle to make the clamping piece drive the inner tube of the filter element to move, thereby facilitating the extraction and replacement of the filter element;

[0026] 3. By setting a protrusion on the clamping piece and opening a slope on the protrusion so that the slope can abut against the boss, the user pushes the clamping piece to automatically deform the clamping piece, so that the protrusion can slide from one side of the boss to the other side, and the clamping surface of the protrusion abuts against the boss, so that the inner tube of the filter element and the clamping piece remain tightly connected.

[0032] The present application is further described in detail below with reference to the accompanying drawings.

[0033] The present application discloses a fuel filter element that is easy to disassemble and assemble. Figure 1 、 Figure 2 and Figure 3 , including a filter element inner tube 1 and a clamping member 2. The filter element inner tube 1 is a cylindrical structure. The filter element inner tube 1 is provided with filter paper on the outer cover. When the filter paper has been used in the filter for a long time, it is necessary to remove the filter and replace the filter paper. By using the clamping member 2 which is detachably connected to the filter element inner tube 1, the filter element inner tube 1 can be pulled out from the filter housing to achieve the effect of replacing the filter paper.

[0034] Reference Figure 1 and Figure 2 The inner wall of the filter cartridge inner barrel 1 is provided with a boss 11, which is fixed to one end of the filter cartridge inner barrel 1. The boss 11 is a circular ring structure and is coaxial with the filter cartridge inner barrel 1. The clamping member 2 is used to be inserted into the filter cartridge inner barrel 1 and can be clamped on one side of the boss 11. By pulling the clamping member 2, the user can drive the clamping member 2 to pull the filter cartridge inner barrel 1 out of the filter housing.

[0035] Reference Figure 3 and Figure 4 The clamping member 2 comprises a connecting plate 21, a clip 22, and a handle 23. The connecting plate 21 is a circular disc, with the clip 22 fixed to one side. The handle 23 is located on the other side. The clip 22 is inserted into the filter cartridge inner barrel 1 and engages with the boss 11. Once the clip 22 is engaged with the filter cartridge inner barrel 1, the user can grasp the handle 23 and pull the filter cartridge inner barrel 1, thereby replacing the filter cartridge. This reduces fuel corrosion on the user's hands during filter cartridge replacement, keeping their hands clean.

[0036] Reference Figure 3 and Figure 4The clamping member 22 is a cylindrical structure, and one end of the clamping member 22 is coaxially connected to the connecting plate 21. A plurality of protrusions 221 are provided on the outer wall of the clamping member 22, and the protrusions 221 are arranged at equal intervals along the circumference of the clamping member 22. When the clamping member 22 is inserted into the filter cartridge inner barrel 1, the protrusions 221 engage with the boss 11. The protrusions 221 are provided with an inclined surface 222, which is provided at the bottom of the protrusion 221. When the clamping member 22 is inserted into the filter cartridge inner barrel 1, the protrusions 221 abut against the boss 11 via the inclined surface 222. The clamping member 22 is elastic, and the clamping member 22 can drive the protrusions 221 to be inserted into the inner side of the filter cartridge inner barrel 1 and engage with the boss 11. The surface of the protrusion 221 is provided with a clamping surface 223, which is a horizontal surface and is provided on the side of the protrusion 221 away from the inclined surface 222. When the clamping member 22 is clamped with the filter element inner barrel 1 , the protrusion 221 contacts the boss 11 through the clamping surface 223 . At this time, the user pulls the clamping member 2 to drive the filter element inner barrel 1 to move.

[0037] Reference Figure 3 and Figure 4 The clamping member 22 is provided with a plurality of equally spaced clearance grooves 224, which extend through the clamping member 22, creating a gap at the end of the clamping member 22. When the clamping member 22 is inserted into the filter cartridge inner barrel 1, the protrusion 221 abuts against the boss 11, causing the clamping member 22 to deform. The clearance grooves 224 allow the clamping member 22 to deform significantly under load, allowing the protrusion 221 to slide on the surface of the boss 11, thereby moving the protrusion 221 from one side of the boss 11 to the other.

[0038] Reference Figure 3 and Figure 4 A chamfer 225 is provided on the end surface of the clamping member 22 away from the connecting plate 21. The diameter of the end surface of the clamping member 22 away from the connecting plate 21 is smaller. When the clamping member 22 is inserted into the filter element inner tube 1, the chamfer 225 plays a guiding role, so that the clamping member 22 can be quickly inserted into the filter element inner tube 1.

[0039] Reference Figure 3 and Figure 4 The connecting plate 21 has a connecting hole 211 at its center. The connecting hole 211 extends through the connecting plate 21. When the clip 22 is inserted into the filter cartridge inner barrel 1, fuel may accumulate therein. When the connecting plate 21 is positioned within the filter cartridge inner barrel 1, the clip 22 may be difficult to insert or may cause fuel to splash during insertion. Providing the connecting hole 211 in the connecting plate 21 reduces fuel splashing and facilitates use.

[0040] Reference Figure 3 and Figure 4A weight-reducing hole 231 is provided in the middle of the handle 23 , and the weight-reducing hole 231 runs through the handle 23 . The weight-reducing hole 231 is used to reduce the weight of the clamping member 2 , thereby facilitating carrying and use.

[0041] The implementation principle of the embodiment of the present application is: by setting a boss 11 on the inner wall of the filter element inner tube 1, the outer side of the filter element inner tube 1 is made smooth and filter paper can be installed; by detachably connecting the clamping part 2 on the filter element inner tube 1, the clamping part 2 can be clamped on the boss 11, so that it is convenient for the user to pull out and replace the filter element inner tube 1 through the clamping part 2; by setting a protrusion 221 on the clamping part 22, the user can insert the clamping part 22 into the filter element inner tube 1 so that the protrusion 221 can be clamped on the inner side of the boss 11, thereby stably connecting the clamping part 2 to the filter element inner tube 1 and facilitating use.

[0042] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
