Description

Technical Field

[0001] The utility model relates to the field of automobile filters, and more particularly to an automobile filter with an easy-to-replace filter element. Background Art

[0002] A filter is a component that filters impurities or gases through filter paper. It typically refers to automotive filters, which are engine accessories. These filters are categorized by their function: oil filters, fuel filters, air filters, and cabin air filters. An engine has three filters: air, oil, and fuel, commonly referred to as the "three filters." Adding the cabin air filter makes this the "four filters." These filters are responsible for filtering the lubrication system, the combustion system's media, the engine's intake system, and the cabin air circulation system, respectively.

[0003] When replacing the filter element of some existing filters, the entire filter needs to be opened to remove the filter element for cleaning or replacement. Some filter housings are not removable, so if you want to replace the filter element, you have to replace the entire filter, which wastes resources and consumes too much cost. Therefore, to solve the above problems, we have proposed an automotive filter that allows for easy replacement of the filter element. Utility Model Content

[0004] In order to solve the above problems, the utility model provides an automobile filter that is easy to replace the filter element, adopting the following technical solutions:

[0005] An automobile filter for easily replacing a filter element comprises a housing, a top cover being provided at the top of the housing, an inlet and outlet pipe being provided on the side opposite to the top cover, two symmetrically distributed bolts being provided at the top of the top cover, the bottom ends of the two bolts being threaded through the top cover, and a screw groove matching the bolts being provided on the side of the housing near the top cover;

[0006] A filter element body is slidably mounted in the housing, and two symmetrically distributed positioning blocks are fixedly mounted on the bottom end of the filter element body. A first positioning groove matching the positioning blocks is provided on the inner wall of the bottom end of the housing, and movable grooves are provided on the inner walls on both sides of the two first positioning grooves, and limit assemblies are provided in the movable grooves.

[0007] Two symmetrically distributed mounting blocks are fixedly mounted on the side wall of the shell near one end of the top cover, and two symmetrically distributed plug blocks are fixedly mounted on the top of the top cover. The tops of the two mounting blocks are provided with slots that match the plug blocks on the same side, and both slots are provided with receiving grooves, and both receiving grooves are provided with fixing components.

[0008] The filter element body is fixed on the filter element body by the fixing means, and the fixing means is fixed on the filter element body by the fixing means.

[0009] When the filter element body needs to be disassembled and replaced, the screw connection between the bolts and the screw grooves is released, and then the action of the fixing assembly on the same side plug is released. Then the top cover and the shell can be spread out, and the filter element body can be pulled out for replacement or cleaning.

[0010] Furthermore, the limiting assembly includes a limiting rod slidably installed in the movable groove, and a first spring is fixedly connected between the opposite sides of the two limiting rods in the same group and the inner wall of the side opposite to the movable groove on the same side, and limiting grooves matching the limiting rods on the same side are opened on both sides of the positioning block.

[0011] By adopting the above technical solution, when the positioning block installed at the bottom end of the filter element body slides into the first positioning groove of the same group, the positioning block pushes the limiting rod of the same group to slide into the movable groove on the same side, and the limiting rod pushes the first spring on the same side to contract. When the positioning block and the first positioning groove of the same group are completely engaged, the limiting rod returns to its original position under the elastic force of the first spring on the same side, and the limiting rod is engaged with the limiting groove opened on the side wall of the positioning block of the same group, which plays a role in positioning and stabilizing the positioning block, and then plays a role in positioning and stabilizing the filter element body, which is beneficial to maintaining the stability of the placement of the filter element body.

[0012] Furthermore, two symmetrically distributed sliding blocks are fixedly mounted on the side walls at opposite ends of the two limiting rods in the same group, and a sliding groove matching the sliding blocks on the same side is provided on the inner wall of the movable groove.

The cooperation between the slider and the sliding groove is conducive to maintaining the stability of the sliding of the limit rod and helps to prevent the limit rod from leaving the movable groove on the same side.

[0014] Furthermore, the fixing assembly includes a fixing block slidably installed in the storage groove, a second spring is fixedly connected between one end of the fixing block and the inner wall on the side opposite to the storage groove of the same group, a fixing groove is opened on the side wall of the insertion block that matches the end of the fixing block on the same side, and a toggle block is fixedly installed on the side of the two fixing blocks away from the shell, and the two toggle blocks slide through the installation block on the same side away from the end of the shell.

[0015] By adopting the above technical solution, when the insertion block slides into the slot on the same side, the insertion block pushes the fixed block of the same group to slide in the receiving slot, and the fixed block pushes the second spring of the same group to contract. When the insertion block and the slot are completely engaged, the fixed block returns to its original position under the elastic force of the second spring of the same group, and the fixed block is engaged with the fixed slot opened on the side wall of the insertion block on the same side, which can play the role of fixing the insertion block and then play the role of fixing the top cover. When the top cover needs to be removed, the staff pulls the fixed block of the same group to slide into the receiving slot by the toggle block, so that the fixed block and the fixed slot opened on the side wall of the insertion block of the same group are disengaged, and then the top cover and the shell can be separated, which makes it convenient for the staff to disassemble and replace the filter element body.

[0016] Furthermore, the two fixing blocks are fixedly installed with stabilizing blocks at the top and bottom of one end of the second spring in the same group, and the top inner wall and the bottom inner wall of the storage groove are provided with stabilizing grooves matching the stabilizing blocks on the same side.

[0017] By adopting the above technical solution, when the fixed block slides in the storage groove, the fixed block slides with the stabilizing block in the stabilizing groove on the same side. The cooperation between the stabilizing block and the stabilizing groove is conducive to maintaining the sliding stability of the fixed block and helps to prevent the fixed block from escaping from the same group of storage grooves.

[0018] Furthermore, two symmetrically distributed positioning rods are fixedly mounted on the bottom end of the filter element body, and a second positioning groove matching the positioning rods is formed on the inner wall of the bottom end of the shell.

[0019] By adopting the above technical solution, when the filter element body contacts the inner wall of the bottom end of the shell, the positioning rod installed at the bottom end of the filter element body engages with the second positioning groove of the same group. Through the engagement of the positioning rod and the second positioning groove, the filter element body is positioned and stabilized, which is conducive to maintaining the stability of the placement of the filter element body.
