Description

Technical Field

[0001] This utility model relates to the field of filter technology, specifically a quick-installation automotive oil filter housing. Background Technology

[0002] As one of the core components of a car engine, the oil filter's function is to intercept impurities in the oil (such as metal shavings, carbon deposits, etc.) through the filter element, ensuring that clean oil circulates into the engine, thereby reducing the risk of wear and corrosion of critical components and extending engine life.

[0003] In existing technologies, traditional oil filters generally use threaded connections, requiring multiple rotations (usually 3-5 turns) and the use of special tools (such as filter wrenches). This is time-consuming and prone to slippage or damage to the housing due to narrow operating space, resulting in low installation efficiency. When a traditional oil filter reaches its service limit, the internal bypass valve opens. If there is no end-of-life warning, continued use at this time will lead to blockage of the oil lines, increased pressure, or unclean oil entering the machine, causing irreversible damage and affecting the engine's working efficiency and service life. Utility Model Content

[0022] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0023] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0024] like Figures 1-8 As shown, a quick-installation automotive oil filter housing includes: a mounting base 1, with a filter body 2 at the bottom of the mounting base 1, and a housing 3 fixedly connected to the bottom of the filter body 2; a snap-fit ​​assembly disposed between the mounting base 1 and the filter body 2, the snap-fit ​​assembly including: a limiting port 103, a slide rail 104, an end cap 4, a handle 401, a spring 402, a limiting block 403, an opening groove 404, a sliding groove 405, and a receiving groove 406; and a sounding assembly disposed at the bottom of the filter body 2, the sounding assembly including: the housing 3, a copper sheet 301, a wire 302, a copper block 303, a buzzer 304, a return spring 305, and a valve core 306.

[0025] The design incorporates several key features. Firstly, the traditional threaded connection used in oil filters is eliminated by using a snap-fit ​​structure where the housing connects to the engine interface without threads. During installation, simply aligning and rotating 30°~45° completes the locking process, requiring no special tools. This facilitates quick installation between the mounting base 1 and the filter body 2, improving installation and disassembly efficiency. Secondly, the inclusion of a buzzer component ensures timely replacement. When the filter reaches its operating limit, the increased internal pressure opens the bypass valve, causing the valve core 306 to activate the copper block 303, which in turn powers the buzzer 304. This promptly alerts the user to replace the filter, ensuring its proper functioning and improving engine efficiency and lifespan.

[0026] An end cap 4 is provided between the mounting base 1 and the filter body 2. The bottom of the end cap 4 is threaded to the filter body 2. Two annular grooves are provided at the bottom of the mounting base 1 and the top of the end cap 4. An inner washer 101 and an outer washer 102 are respectively installed in the two annular grooves. Four slide rails 104 are fixedly connected to the bottom of the mounting base 1. One slide rail 104 has a limit port 103. Four sliding grooves 405 are provided on the side of the end cap 4. One sliding groove 405 has a receiving groove 4 on its side. 06. A limiting block 403 is slidably connected inside the receiving groove 406. An opening groove 404 is opened at the bottom of the sliding groove 405. A handle 401 is slidably connected inside the opening groove 404. A spring 402 is fixedly connected to one side of the handle 401. One end of the spring 402 is fixedly connected to the inner wall of the opening groove 404. The bottom of the limiting block 403 is fixedly connected to the handle 401. The slide rail 104 is slidably connected to the sliding groove 405. The outer side of the mounting base 1 is marked with a mark 105. The outer side of the filter body 2 is marked with a mark 203.

[0027] During installation, the bottom of the mounting base 1 is slidably connected to the filter body 2, and the markings 105 and 203 are aligned. The filter body 2 drives the end cap 4 to press against the inner gasket 101 and the outer gasket 102. Rotating the filter body 2 causes the end cap 4 to rotate, making the slide rail 104 slide in the slide groove 405. After rotating a certain angle, the limiting block 403 contacts the slide rail 104, causing the limiting block 403 to retract to the bottom of the receiving groove 406, and driving the handle 401 in the opening groove. The handle 401 slides inward while the handle 404 compresses the spring 402. When rotated to the locking position, the spring 402 releases its elastic force to push the handle 401 outward. The handle 401 drives the limiting block 403 to embed into the limiting port 103, thereby limiting and locking, achieving quick installation. After installation, the inner washer 101 and the outer washer 102 release their elastic force to push the filter body 2, so that the upper end face of the slide rail 104 fits tightly with the upper end face of the slide groove 405, achieving a sealing effect.

[0028] The filter body 2 has an oil outlet chamber 201 and an oil inlet chamber 202. The oil outlet chamber 201 is equipped with a filter cylinder, and a return spring 305 is connected inside the filter cylinder. A valve core 306 is located at the bottom of the return spring 305. The bottom end of the valve core 306 extends out of the filter body 2 into the housing 3. Wires 302 are provided on both sides of the housing 3. Two symmetrically arranged copper plates 301 are provided inside the housing 3. A copper block 303 is fixedly connected to the bottom end of the valve core 306. A buzzer 304 is provided at the bottom of the housing 3. The buzzer 304 has its own power supply and is connected to the copper plates 301 through the wires 302.

[0029] When the filter reaches its service limit, the filter element becomes clogged with too many impurities, making it difficult for the oil in the inlet chamber 202 to pass through the filter element and enter the outlet chamber 201. The oil pressure inside the inlet chamber 202 increases and overcomes the elasticity of the return spring 305, pushing up the valve core 306, allowing the oil in the inlet chamber 202 to enter the outlet chamber 201. This prevents damage to the engine due to interruption of oil supply. At the same time, the valve core 306 drives the copper block 303 to slide upward in the housing 3, so that the copper block 303 contacts the two copper plates 301. The wire 302, copper plates 301, copper block, and buzzer 304 form a circuit, and the buzzer 304 is energized and sounds, thus reminding the user to replace the filter in time, ensuring the normal operation of the filter, and improving the working efficiency and service life of the engine.

[0030] Working principle:

[0031] During installation, the bottom of the mounting base 1 is slidably connected to the filter body 2, and the markings 105 and 203 are aligned. The filter body 2 drives the end cap 4 to press against the inner gasket 101 and the outer gasket 102. Rotating the filter body 2 causes the end cap 4 to rotate, making the slide rail 104 slide in the slide groove 405. After rotating a certain angle, the limiting block 403 contacts the slide rail 104, causing the limiting block 403 to retract to the bottom of the receiving groove 406, and driving the handle 401 in the opening groove. The handle 401 slides inward while the handle 404 compresses the spring 402. When rotated to the locking position, the spring 402 releases its elastic force to push the handle 401 outward. The handle 401 drives the limiting block 403 to embed into the limiting port 103, thereby limiting and locking, achieving quick installation. After installation, the inner washer 101 and the outer washer 102 release their elastic force to push the filter body 2, so that the upper end face of the slide rail 104 fits tightly with the upper end face of the slide groove 405, achieving a sealing effect.

[0032] When the filter reaches its service limit, the filter element becomes clogged with too many impurities, making it difficult for the oil inside the inlet chamber 202 to pass through the filter element and enter the outlet chamber 201. The oil pressure inside the inlet chamber 202 increases and overcomes the elasticity of the return spring 305, pushing up the valve core 306. This allows the oil inside the inlet chamber 202 to enter the outlet chamber 201 through the drain, preventing damage to the engine due to interruption of oil supply. At the same time, the valve core 306 drives the copper block 303 to slide upward in the housing 3, so that the copper block 303 contacts the two copper plates 301. The wire 302, copper plates 301, copper block, and buzzer 304 form a circuit, and the buzzer 304 is energized and sounds, thus reminding the user to replace the filter in time, ensuring the normal operation of the filter, and improving the engine's working efficiency and service life.
