Description

Technical Field

[0001] This utility model relates to the field of oil pump technology, and in particular to an oil pump outlet filter element structure. Background Technology

[0002] An oil pump is a lightweight and compact pump, which comes in three main types: inline, distribution, and single-unit. An oil pump requires a power source to operate. Its lower camshaft is driven by the engine crankshaft gear. During the operation of the oil pump, a filter structure needs to be installed at the oil outlet to filter the lubricating oil.

[0003] A search revealed a Chinese patent (application number "202020686250.6") disclosing "a filter for an oil pump outlet." This filter includes an oil pump assembly comprising an emergency oil pump, an inlet pipe, a first flange, an outlet pipe, and a second flange; a filter assembly comprising an oil injection pipe, a connecting pipe, internal threads, a filter tube, a filter screen, an oil drain pipe, and a groove. One end of the oil injection pipe is connected to the connecting pipe, the inner wall of the connecting pipe has internal threads, and the inner wall of the connecting pipe is threaded to the filter tube via these internal threads. The outer wall of the filter tube has a groove, and a filter screen is installed on the side of the filter tube away from the connecting pipe. The side of the filter tube away from the connecting pipe is connected to the oil drain pipe; a rotating assembly comprising a motor, a shaft, a drive gear, a driven gear, a fixed ring, an inner ring, a magnetic protrusion, a limiting groove, a limiting block, a rotating ring, a bracket, and a spiral shaft. However, the above filter has the following problems during use:

[0004] 1. It cannot quickly clean impurities inside the filter tube and filter screen, resulting in low practicality;

[0005] 2. The filter screen cannot be cleaned in real time. The filtered impurities adhere to the filter screen, causing it to become clogged and resulting in poor filtration. Utility Model Content

[0006] This utility model provides an oil pump outlet filter element structure, which solves the problems proposed in the prior art: when filtering lubricating oil at the oil pump outlet, the filter cannot quickly clean the impurities inside the filter tube and filter screen, resulting in low practicality, inability to clean the filter screen in real time, and the filtered impurities adhering to the filter screen, causing filter screen blockage and poor filtration effect.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An oil pump outlet filter element structure includes a filter cartridge disposed at the oil pump outlet end. The filter cartridge includes a cylinder body and a bottom cover connected to the outer wall of the bottom of the cylinder body via a flange. A transmission mechanism is provided at the lower part of the cylinder body. The transmission mechanism includes a mounting shaft, several transmission blades respectively fixed on the lower outer wall of the mounting shaft, and an upper fixed frame connected to the upper outer wall of the mounting shaft via bearings. A filter assembly is provided at the upper part of the mounting shaft. The filter assembly includes a mounting frame with four mounting holes on its outer wall, four filter screens respectively embedded in the mounting holes, a return spring abutting against the top outer wall of the upper fixed frame, and a limiting block connected to the top outer wall of the mounting frame via bolts. A pressing component is provided on the limiting block. The pressing component includes a mounting ring connected to the upper outer wall of the mounting shaft via a pin and several limiting rods respectively welded to the outer wall of the mounting ring. A flow guiding component is provided at the upper part of the cylinder body. The flow guiding component includes a flow guiding block and several flow guiding blades respectively welded to the outer wall of the flow guiding block.

[0009] Preferably, a connecting pipe is fixedly provided on the lower inner wall of one side of the cylinder, and the connecting pipe is connected to the outer wall of the oil pump outlet end through a flange, and an oil drain pipe is fixedly provided on the upper inner wall of one side of the cylinder.

[0010] Preferably, a cross-shaped lower fixing frame is connected to the lower outer wall of the mounting shaft via a bearing, and four lower sliding blocks are welded to the outer wall of the lower fixing frame. Four sliding grooves are opened on the lower inner wall of the cylinder, and the four lower sliding blocks are slidably installed in the four sliding grooves respectively. Four upper sliding blocks are welded to the outer wall of the upper fixing frame, and the four upper sliding blocks are slidably installed in the four sliding grooves respectively. A retaining ring is bolted to the top outer wall of the upper fixing frame.

[0011] By removing the bottom cover and pulling the mounting shaft, multiple lower and upper sliders can be moved along four slide grooves, thereby removing the mounting shaft, lower fixing bracket, and upper fixing bracket.

[0012] Preferably, the mounting bracket is bolted to the inner wall of the middle part of the cylinder, and the mounting bracket is slidably mounted on the outer wall of the upper part of the mounting shaft. The reset spring is sleeved on the inner wall of the middle part of the cylinder, and the limiting block is slidably sleeved on the inner wall of the cylinder.

[0013] Preferably, several of the limiting rods abut against the top outer wall of the limiting block, and one end of each of the limiting rods abuts against the inner wall of the cylinder.

[0014] Preferably, a limiting ring is bolted to the inner wall of the cylinder, and the limiting ring abuts against the outer wall of several limiting rods.

[0015] The above method involves pumping lubricating oil into the cylinder, which impacts the drive blades, causing them to rotate the mounting shaft and multiple limit rods. The limit rods then press against the limit block and the return spring, and under the tension of the return spring, the limit block is lifted, allowing the limit block and multiple filter screens to move up and down, thereby shaking off impurities from the bottom of the filter screens.

[0016] Preferably, an installation rod is welded to the top outer wall of the guide block, and the installation rod is bolted to the top inner wall of the cylinder.

[0017] The beneficial effects of this utility model are as follows:

[0018] 1. Remove the bottom cover and pull the mounting shaft to move multiple lower and upper sliders along the four slide grooves. This allows you to pull out the mounting shaft, lower fixing bracket, and upper fixing bracket, and then pull out multiple sets of filter screens for cleaning. This allows for quick disassembly and cleaning of the filter screens, improving practicality.

[0019] 2. The oil pump delivers lubricating oil into the cylinder. The lubricating oil impacts the transmission blades, causing them to drive the mounting shaft and multiple limit rods to rotate. The limit rods squeeze the limit block and the return spring. Under the tension of the return spring, the limit block is lifted, allowing the limit block and multiple filter screens to move up and down. This shakes off impurities at the bottom of the filter screens. When filtering lubricating oil, the up-and-down movement of the filter screens shakes off impurities, preventing filter screen blockage and improving the filtration effect.

[0020] In summary, this utility model allows for quick disassembly and cleaning of the filter screen, improving its practicality. When filtering lubricating oil, the filter screen moves up and down to shake off impurities, preventing clogging and improving the filtration effect. Attached Figure Description
