Description

Technical Field

[0001] This utility model relates to the technical field of air filters for motorcycles, specifically to a low flow resistance air filter for two-wheeled motorcycles. Background Technology

[0002] In a motorcycle engine's intake system, the air filter is a crucial component for ensuring air quality and protecting the equipment's stable operation. Its core function is to remove various impurities from the air, preventing dust, particles, oil, and other pollutants from damaging the engine. Existing air filters mostly use a direct intake method, causing airflow to concentrate in the central area of ​​the filter element. This results in insufficient airflow coverage in that area, causing uneven airflow distribution on the filter element surface, increasing intake resistance, and reducing ventilation efficiency. This paper proposes a low-flow-resistance air filter for motorcycles to address these problems. Utility Model Content

[0003] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0004] To address the technical problems mentioned in the background section above, some embodiments of this application provide a low-flow-resistance air filter for two-wheeled motorcycles, including a housing, a sealing ring disposed on the housing, a detachable cover plate disposed on the housing, an intake pipe fixedly disposed on the housing, a filter device disposed inside the housing, and an exhaust pipe fixedly disposed on the housing. The filter device includes a V-shaped outer filter element detachably disposed on the housing, a V-shaped inner filter element detachably disposed on the housing, two first T-shaped limiting rods respectively fixedly disposed at both ends of the V-shaped outer filter element, two second T-shaped limiting rods fixedly disposed at both ends of the V-shaped inner filter element, four limiting grooves disposed on the housing, a support assembly disposed on the housing, and a flow guiding assembly disposed on the housing.

[0005] Specifically, the support assembly includes an arc-shaped plate movably disposed on the housing for supporting the V-shaped outer filter element, and a V-shaped support mesh fixedly disposed on the housing for supporting the inner filter element.

[0006] Specifically, the support assembly further includes a straight plate fixed to the housing, a telescopic rod fixed at both ends to the straight plate and the arc plate respectively, and a compression spring fixed at both ends to the straight plate and the arc plate respectively; the compression spring is sleeved on the telescopic rod.

[0007] Specifically, the flow guiding assembly is provided in four sets; the flow guiding assembly includes an arc-shaped baffle fixed on the housing and a plurality of arc-shaped flow guiding plates evenly distributed on the arc-shaped baffle.

[0008] Specifically, the pore size of the V-shaped outer filter element is larger than that of the V-shaped inner filter element.

[0009] Specifically, the pore density of the V-shaped outer filter element is less than that of the V-shaped inner filter element.

[0010] Specifically, the V-shaped outer filter element is a metal wire mesh; the V-shaped inner filter element is an activated carbon fiber mesh.

[0011] The beneficial effects of this utility model are:

[0012] (1) The V-shaped outer filter and the V-shaped inner filter, together with the flow guiding components on the housing, can guide the orderly flow of air. The air is evenly distributed on the surface of the V-shaped outer filter and the V-shaped inner filter, reducing turbulence and local resistance peaks, reducing intake resistance, and ensuring sufficient intake.

[0013] (2) The V-shaped outer filter element and the V-shaped inner filter element form a two-stage filtration system: the outer filter element initially intercepts large-volume impurities, while the inner filter element adsorbs small-volume pollutants such as oil and odors. The V-shaped structure significantly increases the contact area between the V-shaped outer filter element and the airflow, prolonging the residence time of the gas on the surface of the V-shaped outer filter element and the V-shaped inner filter element, thus achieving efficient graded filtration of impurities of different particle sizes.

[0014] (3) The rigid structure of the metal wire mesh ensures the impact resistance of the outer filter element, which is suitable for coarse filtration; the high adsorption characteristics of the activated carbon fiber mesh are for fine pollutants. The two-stage filtration has a clear division of labor, taking into account both filtration efficiency and service life. Attached Figure Description

[0026] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] Reference Figures 1-4 As shown, the present invention discloses a low flow resistance air filter for a two-wheeled motorcycle, comprising a housing 1, a sealing ring 2 disposed on the housing 1, a cover plate 3 detachably disposed on the housing 1, an air inlet pipe 4 fixedly disposed on the housing 1, a filter device 5 disposed inside the housing 1, and an air outlet pipe 6 fixedly disposed on the housing 1. The filter device 5 includes a V-shaped outer filter element 51 detachably disposed on the housing 1, a V-shaped inner filter element 52 detachably disposed on the housing 1, two first T-shaped limiting rods 53 respectively fixed at both ends of the V-shaped outer filter element 51, two second T-shaped limiting rods 54 fixed at both ends of the V-shaped inner filter element 52, four limiting grooves 55 disposed on the housing 1, a support assembly 56 disposed on the housing 1, and a flow guiding assembly 57 disposed on the housing 1.

[0028] Air enters the housing 1 through the intake pipe 4, first passing through the flow guide assembly 57, then through the V-shaped outer filter element 51 for preliminary filtration, removing large-volume impurities. It then passes through the V-shaped inner filter element 52, which adsorbs small-volume impurities such as oil. The design of the flow guide assembly 57, the V-shaped outer filter element 51, and the V-shaped inner filter element 52 ensures that the airflow evenly covers the surfaces of the V-shaped outer filter element 51 and the V-shaped inner filter element 52 after entering the rear housing 1, avoiding the central area overflow problem caused by traditional direct air intake and reducing intake resistance. The V-shaped structure significantly increases the contact area between the airflow and the V-shaped outer filter element 51 and the V-shaped inner filter element 52, extending the residence time of the gas on the surfaces of the V-shaped outer filter element 51 and the V-shaped inner filter element 52. This achieves efficient graded filtration of impurities of different particle sizes, solving the problem that traditional air filters cannot simultaneously achieve low flow resistance and high filtration efficiency. The support component 56 ensures that the V-shaped outer filter element 51 and the V-shaped inner filter element 52 remain taut at all times, preventing localized dents during high-speed air intake and ensuring filtration efficiency. For replacement or cleaning, simply open the cover plate 3 to horizontally pull out the V-shaped outer and inner filter elements along the limiting groove 55; for installation, simply push them in in the opposite direction to complete the positioning. This design eliminates the complex disassembly and assembly process of traditional filter elements, significantly shortening maintenance time, improving equipment maintainability, and reducing labor costs.

[0029] Specifically, the support assembly 56 includes an arc plate 561 movably disposed on the housing 1 for supporting the V-shaped outer filter element 51, and a V-shaped support mesh 562 fixedly disposed on the housing 1 for supporting the inner filter element.

[0030] Specifically, the support assembly 56 further includes a straight plate 563 fixedly mounted on the housing 1, a telescopic rod 564 with its two ends fixedly mounted on the straight plate 563 and the arc plate 561 respectively, and a compression spring 565 with its two ends fixedly mounted on the straight plate 563 and the arc plate 561 respectively; the compression spring 565 is sleeved on the telescopic rod 564.

[0031] Specifically, the V-shaped outer filter element 51 is a metal wire mesh; the V-shaped inner filter element 52 is an activated carbon fiber mesh. The rigid structure of the metal wire mesh ensures the impact resistance of the outer filter element, making it suitable for coarse filtration; the high adsorption characteristics of the activated carbon fiber mesh target fine pollutants. The two-stage filtration has a clear division of labor, balancing filtration efficiency and service life.

[0032] The support assembly 56 includes a V-shaped support mesh (fixed to support the V-shaped inner filter element 52) ​​and a movable arc-shaped plate 561 (supporting the V-shaped outer filter element 51), which, together with the telescopic rod 564 and the compression spring 565, form an elastic support structure. When there is a slight error in the length of the V-shaped outer filter element 51, the compression spring 565 can adaptively adjust by compression or extension to keep the V-shaped outer filter element 51 always taut, avoiding local dents or deformations caused by airflow impact during high-speed air intake, ensuring that the V-shaped outer filter element 51 works stably under high-pressure environments and maintains high-efficiency filtration performance over a long period of time.

[0033] Specifically, the flow guiding component 57 is provided in four sets; the flow guiding component 57 includes an arc-shaped baffle 571 fixed on the housing 1 and a plurality of arc-shaped flow guiding plates 572 equally distributed on the arc-shaped baffle 571.

[0034] Four sets of flow guiding components 57 are symmetrically arranged inside the housing 1. Two sets of flow guiding components 57 are located on the housing 1 near the end of the air intake pipe 4, and two sets of flow guiding components 57 are located on the housing 1 near the end of the air outlet pipe 6, which reduces the air intake and air outlet resistance.

[0035] Specifically, the pore size of the V-shaped outer filter element 51 is larger than the pore size of the V-shaped inner filter element 52.

[0036] Specifically, the pore density of the V-shaped outer filter element 51 is less than that of the V-shaped inner filter element 52.

[0037] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in the embodiments of this disclosure is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept.
