Description

Technical Field

[0001] This utility model relates to the field of engine parts technology, and in particular to an intake bend filter assembly. Background Technology

[0002] Agricultural and engineering equipment often operate in harsh environments with high dust and debris. If sand, dust, and other impurities in the air enter the engine of the equipment, they will accelerate the wear of precision components, affect operational stability, and shorten the equipment's lifespan. Therefore, an intake bend filter assembly is installed to efficiently intercept solid impurities and harmful particles in the intake air, purify the intake air quality, and at the same time, work with the intake bend to optimize the airflow state, buffer airflow fluctuations, stabilize the intake air flow, improve the overall working performance of the equipment, and extend the equipment's service life.

[0003] A search revealed Chinese patent publication number CN219974657U, which discloses a conveniently detachable automotive air filter. The filter includes a filter housing with a cover at its top. A disassembly mechanism connects the cover and the filter housing. An air inlet pipe connects to the top of the cover, and an air outlet pipe connects to the bottom of the filter housing. A filter element is housed inside the filter housing. Mounting plates are fixed to the top and bottom of the filter element. Two slots are provided at the bottom of the cover and the bottom of the inner wall of the filter housing. A locking assembly is provided on the opposite side of the two mounting plates. This utility model relates to the field of air filter technology. This conveniently detachable automotive air filter, through the locking assembly, securely fastens the filter element. When disassembly is needed, opening the cover allows the first spring to return to its original position, enabling the filter element to be removed. This design offers high disassembly and assembly efficiency and strong practicality.

[0004] The aforementioned patent has the following shortcomings: Since the filter element of this patent forms a fixed assembly structure with the filter shell and shell cover through the clamping component, it does not have a filter cartridge cleaning channel or a quick-separation cleaning auxiliary component. It is not convenient to clean the dust and impurities attached to the inner wall of the filter cartridge separately. As a result, the operator has to disassemble the entire filter element before the cleaning operation can be carried out. The cleaning process is cumbersome and time-consuming. Repeated disassembly can also cause elastic fatigue of the clamping component and increase the assembly gap, affecting the subsequent filtration sealing and structural stability.

[0005] To address this, an intake bend filter assembly is proposed. Utility Model Content

[0006] In view of this, the present invention aims to provide an intake bend filter assembly to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial alternative.

[0007] The technical solution of this utility model embodiment is implemented as follows: an intake bend filter assembly includes a housing, and further includes: An exhaust pipe is fixed to the top of one side of the outer shell, and an intake bend is connected to the bottom of the other side of the outer shell. A fixing frame is fitted on the outside of the outer shell, and a filter cartridge is detachably installed inside the outer shell. The mounting and disassembly structure for installing and fixing the filter cartridge is located inside the bottom of the outer casing; A cleaning structure is provided inside the filter cartridge. The cleaning structure includes a rotating rod rotatably connected inside the filter cartridge. Cleaning brushes are fixed on both sides of the rotating rod, and a transmission assembly is provided at the top of the rotating rod. A sludge storage structure for collecting fallen foreign objects is located at the bottom of the loading and unloading structure.

[0008] In some embodiments: the frontal cross-section of the filter cartridge is a frustum-shaped structure, and the outer diameter of the bottom end of the filter cartridge matches the inner diameter of the outer shell.

[0009] In some embodiments: the transmission assembly includes a connecting block fixed to the top of the rotating rod, a geared motor is mounted on the top of the housing, and a connecting sleeve is fixed to the end of the output shaft of the geared motor.

[0010] In some embodiments: the top of the connecting block has a hexagonal cross-section when viewed from above, and the top of the connecting sleeve has a hexagonal groove that matches the connecting block, and the connecting block and the connecting sleeve form a plug-in structure.

[0011] In some embodiments: the loading and unloading structure includes a mounting sleeve fixed to the bottom end of the housing, a mounting cover threaded to the outer side of the bottom end of the mounting sleeve, a support frame fixed to the top of the mounting cover, a guide sleeve fixed to the top of the inside of the housing, a positioning sleeve slidably connected to the bottom end of the guide sleeve, and a telescopic spring connected to the guide sleeve fixed to the top of the positioning sleeve.

[0012] In some embodiments: the positioning sleeve and the top end of the filter cartridge form an insertion and removal structure, and the positioning sleeve and the guide sleeve form a telescopic structure through a telescopic spring.

[0013] In some embodiments: the sludge storage structure includes a sludge storage box fixed to the bottom end of the mounting cover, a screw cap is threaded to the outer side of the top of the sludge storage box, and a brush rod is fixed inside the screw cap.

[0014] In some embodiments: the end of the brush handle away from the screw cap extends into the interior of the sludge collection box, and the outer side of the brush handle is spirally arranged with bristles.

[0015] The present invention has the following advantages due to the adoption of the above technical solution: An air intake bend filter assembly automatically cleans itself by starting a geared motor to drive the connecting sleeve and connecting block to rotate synchronously, which in turn drives the rotating rod to rotate, causing the cleaning brush to clean the inner wall of the filter cartridge. This eliminates the need for frequent manual disassembly of the filter element, simplifies the cleaning process, shortens equipment downtime for maintenance, and avoids component wear and assembly gap problems caused by repeated disassembly and assembly.

[0016] An air intake bend filter assembly allows the filter cartridge to be easily removed by unscrewing the mounting cover and simultaneously pushing the filter cartridge out of the housing using a telescopic spring. This facilitates easy replacement of the device, reduces replacement time, improves the continuous operation efficiency of agricultural and engineering equipment, and allows ordinary operators to complete the replacement process, saving on professional maintenance costs.

[0017] An intake bend filter assembly collects impurities swept away by the cleaning structure through a sludge collection box. By rotating the cap, foreign objects inside the sludge collection box can be discharged, thereby realizing the foreign object collection function of this device. This can prevent the intercepted impurities from accumulating inside the assembly and causing blockages. At the same time, it can quickly complete the discharge operation, adapting to the continuous operation requirements of high dust conditions.

[0018] The above overview is for illustrative purposes only and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features of the present invention will become readily apparent from the accompanying drawings and the following detailed description.

[0024] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings. Example 1

[0025] like Figures 1 to 4 As shown, an intake bend filter assembly includes a housing 1, and further includes: The exhaust pipe 3 is fixed to the top of one side of the outer shell 1, and the bottom of the other side of the outer shell 1 is connected to the intake bend pipe 5. The outer side of the outer shell 1 is fitted with a fixing bracket 2, and the filter cartridge 8 is detachably installed inside the outer shell 1. The mounting and dismounting structure 6 for installing and fixing the filter cartridge 8 is located inside the bottom end of the outer casing 1; Cleaning structure 4 is located inside filter cartridge 8; A sludge storage structure 7, used for the centralized collection of fallen foreign objects, is located at the bottom of the loading and unloading structure 6.

[0026] The frontal cross-section of the filter cartridge 8 is a frustum-shaped structure, and the outer diameter of the bottom end of the filter cartridge 8 matches the inner diameter of the outer shell 1.

[0027] In this embodiment, when the air intake bend filter assembly is needed, outside air is introduced into the housing 1 through the air intake bend 5. At the same time, the air flows through the filter cartridge 8 to intercept impurities. The purified air is discharged through the air outlet pipe 3 for use by the equipment. The mounting and dismounting structure 6 is used to install and fix the filter cartridge 8 so as to facilitate quick mounting, dismounting and replacement of the filter cartridge 8. When too much foreign matter is attached to the surface of the filter cartridge 8, the cleaning structure 4 is used to automatically clean the filter cartridge 8 to ensure that the filter cartridge 8 is unobstructed. The dirt storage structure 7 is used to collect the fallen foreign matter.

[0028] like Figures 1 to 4 As shown, the cleaning structure 4 includes a rotating rod 404 rotatably connected inside the filter cartridge 8. Cleaning brushes 405 are fixed on both sides of the rotating rod 404. A transmission assembly is provided at the top of the rotating rod 404. The transmission assembly includes a connecting block 403 fixed at the top of the rotating rod 404. A reduction motor 401 is installed at the top of the outer casing 1. A connecting sleeve 402 is fixed at the end of the output shaft of the reduction motor 401. The top cross-section of the connecting block 403 is a regular hexagonal structure, and a hexagonal groove matching the connecting block 403 is opened inside the top of the connecting sleeve 402. The connecting block 403 and the connecting sleeve 402 form a plug-in structure.

[0029] In this embodiment, when impurities adhering to the surface of the filter cartridge 8 affect the air intake efficiency, the geared motor 401 is started to drive the connecting sleeve 402 to rotate. At the same time, the connecting sleeve 402 drives the rotating rod 404 to rotate through the connecting block 403, so that the cleaning brush 405 cleans the inner wall of the filter cartridge 8, thereby removing the impurities on the filter cartridge 8 and quickly restoring the filtration performance of the filter cartridge 8. Through the plug-and-play connection between the connecting block 403 and the connecting sleeve 402, when the filter cartridge 8 is disassembled and assembled by the mounting and disassembling structure 6, the rotating rod 404 can quickly separate or connect with the output shaft of the geared motor 401 synchronously with the filter cartridge 8, thereby simplifying the disassembly and assembly steps of the filter cartridge 8. Example 2

[0030] An intake bend filter assembly, this embodiment is based on embodiment 1 with the following improvements, such as... Figures 1 to 3 As shown, the loading and unloading structure 6 includes a mounting sleeve 602 fixed to the bottom end of the outer shell 1. A mounting cover 601 is threadedly connected to the outer side of the bottom end of the mounting sleeve 602. A support frame 603 is fixed to the top of the mounting cover 601. A guide sleeve 606 is fixed to the top inside the outer shell 1. A positioning sleeve 604 is slidably connected to the bottom end of the guide sleeve 606. A telescopic spring 605 connected to the guide sleeve 606 is fixed to the top of the positioning sleeve 604. The positioning sleeve 604 and the top of the filter cartridge 8 form an insertion and removal structure. The positioning sleeve 604 and the guide sleeve 606 form a telescopic structure through the telescopic spring 605.

[0031] In this embodiment, when the filter cartridge 8 needs to be replaced, the mounting cover 601 is screwed off to separate it from the mounting sleeve 602. At the same time, the compressed telescopic spring 605 drives the positioning sleeve 604 to move downward and push the filter cartridge 8 out of the housing 1, thereby removing the filter cartridge 8. After replacing the filter cartridge 8, the new filter cartridge 8 is placed on the top of the support frame 603 and inserted into the housing 1. The mounting cover 601 is screwed off in the opposite direction, so that the support frame 603 pushes the filter cartridge 8 upward and fixes it. At the same time, the positioning sleeve 604 compresses the telescopic spring 605 to retract, thereby completing the fixation of the filter cartridge 8. This simplifies the filter cartridge 8 replacement process to a certain extent.

[0032] like Figures 1 to 2 As shown, the sludge storage structure 7 includes a sludge storage box 701 fixed to the bottom of the mounting cover 601. A screw cap 702 is threaded to the outer side of the top of the sludge storage box 701. A brush rod 703 is fixed inside the screw cap 702. One end of the brush rod 703 away from the screw cap 702 extends into the interior of the sludge storage box 701. Brush bristles are arranged in a spiral on the outer side of the brush rod 703.

[0033] In this embodiment, the impurities swept by the cleaning structure 4 are collected by the sludge storage box 701. The sludge storage box 701 can be opened by rotating the screw cap 702. At the same time, the brush rod 703 rotates with the screw cap 702, and the bristles on its outer side disperse the foreign matter, so as to discharge the foreign matter inside the sludge storage box 701, thereby avoiding the accumulation of impurities in the sludge storage box 701 and causing blockage.

[0034] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
