Description

Technical Field

[0001] This application relates to the field of automotive parts, and in particular to an oil bath air filter assembly that facilitates the installation of a filter screen. Background Technology

[0002] An oil bath air filter is a device that filters dust and impurities from the air through an oil bath. It is mainly used in agricultural machinery and industrial equipment. Its working principle is to filter the incoming air using oil in an oil bath, thereby ensuring that the air entering the engine is clean and dust-free.

[0003] Existing oil bath air filters filter dust by using internal filters, which are often installed by winding metal wires and fixing them inside the upper housing. This is cumbersome and inconvenient for later disassembly, replacement, and maintenance. Therefore, the installation effect of the filters and the ease of disassembly and assembly can be further improved. Utility Model Content

[0004] To improve the installation effect of the filter screen and the convenience of subsequent disassembly and assembly, this application provides an oil bath type air filter assembly that facilitates filter screen installation.

[0005] This application provides an oil bath air filter assembly that facilitates filter installation, comprising a first housing and a second housing. The second housing has multiple mounting clips on one side for positioning and installation with the first housing. The first housing has a top cover, on which an air inlet pipe is installed and fixedly mounted, with one end extending above the second housing. An air outlet pipe is located on one side of the first housing. An installation tube is fixedly installed inside the second housing. A first mounting bracket and a second mounting bracket are fitted onto the installation tube. A first filter and a second filter are respectively located on the sides of the first and second mounting brackets that are close to each other. Two mounting boxes are symmetrically fixedly mounted on the outer surface of the installation tube, and each mounting box has a snap-fit ​​mechanism.

[0006] By adopting the above technical solution, external air enters the first and second housings through the intake pipe. The air is first pre-filtered by the filter element to remove large dust and impurities. Then, the pre-filtered air enters the oil sump inside the filter element. In this area, the air comes into contact with a specific oil, which adheres to and removes tiny particles in the air, further improving the cleanliness of the air. The clean air filtered by the oil sump enters the engine through the exhaust pipe to provide the engine with the required oxygen.

[0007] Preferably, the snap-fit ​​mechanism includes two telescopic rods symmetrically fixedly installed inside the mounting box. Each of the two telescopic rods is provided with a telescopic spring. Each telescopic end of the two telescopic rods is fixedly installed with a sliding plate. A second wedge is fixedly installed on the side of the two sliding plates that are close to each other. A first wedge that matches the second wedge is fixedly installed at the bottom of the second mounting frame.

[0008] By adopting the above technical solution, the two first wedges drive the two second wedges to move away from each other. The two second wedges moving away from each other will also drive the two sliding plates to move away from each other, and compress the corresponding telescopic rod and telescopic spring. This will also position and install the first wedges. At this time, the first filter screen and the second filter screen can be installed on the installation pipe.

[0009] Preferably, the top of the mounting box has a mounting groove, and the first wedge is slidably mounted in the mounting groove.

[0010] By adopting the above technical solution and setting up an installation slot, an auxiliary installation function can be achieved.

[0011] Preferably, an oil sump is formed at the bottom of the second housing and below the second mounting bracket, the air inlet pipe is located inside the mounting pipe, and the mounting pipe is located above the oil sump.

[0012] By adopting the above technical solution and setting up the installation pipe, an auxiliary installation function can be achieved.

[0013] Preferably, a threaded sleeve is screwed onto the mounting tube, and the threaded sleeve is located above the first mounting bracket.

[0014] By adopting the above technical solution, a threaded sleeve can be set up to assist in installation and positioning.

[0015] Preferably, both the first and second filters can be detachably mounted on the mounting tube.

[0016] By adopting the above technical solution, and by setting up a first filter and a second filter, it is possible to block dust and other impurities.

[0017] Preferably, two adjusting rods are symmetrically fixedly installed at the ends of the first and second filters that are close to each other. Both adjusting rods are assembled from sleeves and rods and are interlocked. Threaded holes are opened on one outer surface of both adjusting rods, and adjusting bolts are screwed into both threaded holes.

[0018] By adopting the above technical solution, the first filter screen can be moved by stretching the adjusting rod. The distance between the first and second filters screens can be adjusted according to the installation and use requirements. Furthermore, the positions of the first and second filters screens can be limited by rotating the adjusting bolt.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] 1. This application employs the cooperative action of first wedges, etc., where two first wedges are inserted into corresponding mounting slots, thereby causing two second wedges to move away from each other. The two second wedges moving away from each other cause two sliding plates to also move away from each other, compressing the corresponding telescopic rods and telescopic springs, and thus positioning and installing the first wedges. At this time, the first and second filters can be installed on the mounting pipe, thereby completing the installation of the first and second filters. Therefore, it is also convenient for them to be disassembled, replaced, or maintained later, improving the convenience of use and the stability of installation.

[0021] 2. This application employs an adjusting rod or similar device. By stretching the adjusting rod, the first filter screen can be moved. The distance between the first and second filters screens can be adjusted according to installation and usage requirements. Furthermore, by rotating the adjusting bolt, the positions of the first and second filters screens can be limited. Attached Figure Description

[0028] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0029] This application discloses an oil bath air filter assembly that facilitates filter installation.

[0030] Reference Figure 1-3 An oil bath air filter assembly that facilitates filter screen installation includes an oil bath air filter assembly mechanism, a snap-fit ​​mechanism, and an adjustment mechanism;

[0031] The oil bath air filter assembly includes a first housing 1 and a second housing 2. The second housing 2 has multiple mounting clips 3 on one side for positioning and mounting with the first housing 1. These mounting clips 3 are existing technology, so their specific structure and usage are not described in detail. A top cover 4 is located on the top of the first housing 1. An air intake pipe 5 is installed through and fixedly mounted on the top cover 4, with one end of the air intake pipe 5 extending above the second housing 2. An air outlet pipe 6 is located on one side of the first housing 1. A mounting pipe 7 is fixedly installed inside the second housing 2. A first mounting bracket 12 and a second mounting bracket 13 are sleeved on the mounting pipe 7. A first filter screen 10 and a second filter screen 11 are respectively provided on the sides of the first mounting bracket 12 and the second mounting bracket 13 that are close to each other. Two mounting boxes 17 are symmetrically fixedly mounted on the outer surface of the mounting pipe 7. An oil sump 9 is formed at the bottom of the second housing 2 and below the second mounting bracket 13. The air intake pipe 5 is located inside the mounting pipe 7, and the mounting pipe 7 is located above the oil sump 9.

[0032] In use, outside air enters the first housing 1 and the second housing 2 through the intake pipe 5. The air is first filtered by the filter element to remove large particles of dust and impurities. Then, the air that has passed through the filter element enters the oil sump 9 inside the filter element. In this area, the air comes into contact with a specific oil. The oil adheres to and removes the tiny particles in the air, further improving the cleanliness of the air. The clean air filtered by the oil sump 9 enters the engine through the exhaust pipe 6 to provide the engine with the necessary oxygen.

[0033] Reference Figure 4-5The snap-fit ​​mechanism includes two telescopic rods 20 symmetrically fixedly installed inside the mounting box 17, two telescopic springs 21 sleeved on the two telescopic rods 20, and sliding plates 22 fixedly installed at the telescopic ends of the two telescopic rods 20, two second wedges 23 fixedly installed on the side of the two sliding plates 22 close to each other, and a first wedge 19 adapted to the second wedge 23 fixedly installed at the bottom of the second mounting frame 13, a mounting groove 18 opened at the top of the mounting box 17, and the first wedge 19 slidably installed in the mounting groove 18, a threaded sleeve 8 screwed onto the mounting tube 7, and the threaded sleeve 8 located above the first mounting frame 12, and the first filter screen 10 and the second filter screen 11 can be detachably sleeved on the mounting tube 7.

[0034] In use, the two first wedges 19 are inserted into the corresponding mounting slots 18, which will cause the two second wedges 23 to move away from each other. The two second wedges 23 moving away from each other will also cause the two sliding plates 22 to move away from each other, and compress the corresponding telescopic rods 20 and telescopic springs 21, thereby positioning and installing the first wedges 19. At this time, the first filter screen 10 and the second filter screen 11 can be installed on the mounting tube 7.

[0035] Reference Figure 2-3 The adjustment mechanism includes two adjusting rods 14 fixedly installed at the ends of the first filter screen 10 and the second filter screen 11 that are close to each other. Both adjusting rods 14 are assembled from sleeves and rods and are fitted together. Two threaded holes 15 are opened on the outer surface of one side of the two adjusting rods 14, and two adjusting bolts 16 are screwed into the two threaded holes 15.

[0036] In use, by stretching the adjusting rod 14, the first filter screen 10 will move. The distance between the first filter screen 10 and the second filter screen 11 can be adjusted according to the installation and use requirements. Then, by rotating the adjusting bolt 16, the position of the first filter screen 10 and the second filter screen 11 can be limited.

[0037] The implementation principle of an oil bath air filter assembly that facilitates filter installation according to an embodiment of this application is as follows: In use, the second mounting bracket 13 is first installed on the mounting pipe 7 and moved above the two mounting boxes 17. At this time, the two first wedges 19 will be inserted into the corresponding mounting slots 18, thereby causing the two second wedges 23 to move away from each other. The two second wedges 23 moving away from each other will also cause the two sliding plates 22 to move away from each other, and compress the corresponding telescopic rod 20 and telescopic spring 21, thereby positioning and installing the first wedges 19. At this time, the first filter 10 and the second filter 11 can be installed on the mounting pipe 7. By stretching the adjusting rod 14, the first filter 10 will be moved, and the distance between the first filter 10 and the second filter 11 can be adjusted according to the installation and use requirements. By rotating the adjusting bolt 16, the position of the first filter 10 and the second filter 11 can be limited.

[0038] At this point, the first mounting bracket 12 is installed on the mounting tube 7, and the threaded sleeve 8 is rotated on the mounting tube 7, so that the first mounting bracket 12 can be limited and fixed, thereby completing the installation of the first filter screen 10 and the second filter screen 11. This also facilitates disassembly, replacement or maintenance in the later stage, improving the convenience of use and the stability of installation.

[0039] External air enters the first housing 1 and the second housing 2 through the intake pipe 5. The air is first filtered by the filter element to remove large particles of dust and impurities. Then, the air that has passed through the filter element enters the oil sump 9 inside the filter element. In this area, the air comes into contact with a specific oil. The oil adheres to and removes small particles in the air, further improving the cleanliness of the air. The clean air filtered by the oil sump 9 enters the engine through the exhaust pipe 6 to provide the engine with the required oxygen.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
