Description

多功能性引擎室空氣濾清器Multifunctional engine room air filter

本創作係有關於一種空氣濾清器，特別是指一種具有雙重濾淨效果的多功能性引擎室空氣濾清器。This creation is about an air filter, especially a versatile engine room air filter with a double filter effect.

汽車必須靠引擎提供動力，才能在道路上行駛，引擎性能的良否是決定汽車行駛性能的最大因素。目前汽車使用的引擎均屬於內燃機，其功能是將燃料從化學能轉為熱能再轉成機械能，機械能也就是一般所謂的動力，而燃料的燃燒需要大量的空氣；也就是說，引擎運轉時不僅需要燃料，更需要獲得充足的空氣，隨著進氣系統提供了新鮮空氣與燃料混合並進入引擎點燃後，方可完成燃燒產生動力輸出。藉此，使得進氣系統在引擎運轉中，扮演著舉足輕重的角色。The car must be powered by the engine to be able to drive on the road. The good performance of the engine is the biggest factor determining the driving performance of the car. At present, the engines used in automobiles are all internal combustion engines. Their function is to convert fuel from chemical energy to heat energy, and mechanical energy is generally called so-called power. The combustion of fuel requires a lot of air; that is, the engine is running. Not only does it require fuel, but it also needs to get enough air. As the intake system provides fresh air to mix with the fuel and enter the engine to ignite, the combustion can be completed to produce a power output. In this way, the intake system plays a pivotal role in the operation of the engine.

汽車的進氣系統可用來將外部空氣吸入引擎以完成燃燒過程，然而，由於生活中行車進氣的空氣多含灰塵和雜質，這些灰塵微粒若隨著空氣進入引擎的燃燒室，則容易致使汽缸燃燒不完全以及氣管阻塞，使得活塞環、軸承襯套、閥和汽缸壁等引擎組件受到破壞，同時會導致引擎馬力下降，造成行駛不順暢。The intake system of the car can be used to draw outside air into the engine to complete the combustion process. However, since the air in the air intake in life is rich in dust and impurities, if the dust particles enter the combustion chamber of the engine with the air, the cylinder is easily caused. Incomplete combustion and obstruction of the trachea cause damage to engine components such as piston rings, bearing bushings, valves and cylinder walls, and at the same time cause engine horsepower to drop, resulting in poor running.

因此，空氣濾淨器已成為汽車不可或缺的耗材之一。目前的空氣濾淨器通常以棉紙作為其濾芯材質，空氣穿過時會由棉紙將灰塵擋下，但是使用這種棉紙濾芯過濾空氣的效果與使用壽命不佳，並無法長期有效防止空氣中的雜質進入引擎，而增加了引擎的負擔；同時，棉紙濾芯吸水性強，容易引發黴菌滋長造成濾芯的損壞。Therefore, the air filter has become one of the indispensable consumables for automobiles. The current air filter usually uses cotton paper as its filter material. When the air passes through, the dust will be blocked by the cotton paper. However, the effect of using the cotton filter to filter the air and the service life is not good, and the air cannot be effectively prevented for a long time. The impurities in the engine enter the engine, which increases the burden on the engine; at the same time, the cotton paper filter has strong water absorption, which is easy to cause mold damage to cause damage to the filter element.

故，如何突破既有空氣濾淨器的缺失，來大幅提高其使用效益，乃為一具實用價值之技術課題。Therefore, how to break through the lack of existing air filters to greatly improve their use efficiency is a technical issue of practical value.

鑑於以上的問題，本創作的主要目的在於提出一種多功能性引擎室空氣濾清器，其具有由基本過濾層和強化過濾層兩層相疊而成之雙層空氣濾芯，可大幅提昇過濾效能，藉以提昇引擎輸入空氣的品質，從而避免造成汽缸燃燒不完全及氣管阻塞，可延長引擎組件的使用壽命，進而可增強馬力輸出，耗油就減少，提昇行駛性能。In view of the above problems, the main purpose of this creation is to propose a versatile engine room air filter with a double-layer air filter layer formed by stacking two layers of a basic filter layer and a reinforced filter layer, which can greatly improve the filtration efficiency. In order to improve the quality of the engine input air, thereby avoiding incomplete combustion of the cylinder and obstruction of the air pipe, the service life of the engine component can be prolonged, thereby enhancing the horsepower output, reducing the fuel consumption and improving the driving performance.

為達上述目的，本創作所揭露之一種多功能性引擎室空氣濾清器，其包括有框架以及雙層空氣濾芯。其中，框架活動裝設於引擎之進氣系統中進氣口的鄰近處，而雙層空氣濾芯固定於框架上，此雙層空氣濾芯包括相疊的基本過濾層和強化過濾層，且基本過濾層或強化過濾層面向進氣口。To achieve the above object, a versatile engine room air cleaner disclosed in the present invention includes a frame and a double air filter. Wherein, the frame activity is installed in the vicinity of the air inlet of the intake system of the engine, and the double air filter is fixed on the frame, the double air filter comprises a basic filter layer and a reinforced filter layer, and the basic filter The layer or reinforced filter layer faces the air inlet.

本創作中，強化過濾層較佳為整面覆蓋於基本過濾層的一面，其疊構方式主要分為兩種，一種雙層空氣濾芯是由強化過濾層和基本過濾層連續前後折疊形成為一體的波浪狀結構，另一種是由基本過濾層連續前後折疊形成一波浪狀結構，再將強化過濾層覆蓋於基本過濾層的一面的多個折疊彎曲處。In the present invention, the reinforcing filter layer preferably covers the entire surface of the basic filter layer, and the stacking manner is mainly divided into two types. A double-layer air filter element is formed by continuously strengthening the filter layer and the basic filter layer. The wavy structure, the other is that the basic filter layer is continuously folded back and forth to form a wavy structure, and the reinforced filter layer is covered on a plurality of folded bends on one side of the basic filter layer.

另外，本創作之基本過濾層較佳為不織布或紙類濾網，以提供初步的空氣濾淨效果，用來過濾大粒徑的灰塵。而本創作之強化過濾層較佳為不織布、泡綿、多孔性薄膜或靜電濾網，則可提供加強的空氣濾淨效果，用以濾除小粒徑的粉塵、花粉等雜質，如此，可使過濾及吸附效能獲得進一步提升。另外，基本過濾層或強化過濾層更可加入撥水劑處理，使其具有防水表層，來達到防止吸附水氣的作用。另外，本創作中，基本過濾層與強化過濾層可於不織布、泡綿、多孔性薄膜或靜電濾網的製造過程中混入10-50重量百分比（wt％）的含鹵素、含磷、含金屬氫氧化物之阻燃劑或其他具有難燃性質的化學品，或是於基本過濾層3或強化過濾層表面進行處理，進而提高難燃的功能。In addition, the basic filter layer of the present invention is preferably a non-woven or paper filter to provide a preliminary air filtration effect for filtering large particle size dust. The reinforced filter layer of the present invention is preferably a non-woven fabric, a foam, a porous film or an electrostatic filter, which can provide a reinforced air filtering effect for filtering impurities such as dust and pollen of a small particle size. The filtration and adsorption performance are further improved. In addition, the basic filter layer or the reinforced filter layer can be further treated with a water repellent agent to have a waterproof surface layer to prevent adsorption of moisture. In addition, in the present creation, the basic filter layer and the reinforced filter layer can be mixed with 10-50% by weight (% by weight) of halogen-containing, phosphorus-containing, and metal-containing materials in the manufacturing process of non-woven fabric, foam, porous film or electrostatic filter. A hydroxide flame retardant or other chemical with flame retardant properties is treated on the surface of the basic filter layer 3 or the reinforced filter layer to improve the flame retardant function.

因此，在空氣通過多功能性引擎室空氣濾清器時，除了可透過基本過濾層過濾空氣中的較大粒徑的灰塵，也經由強化過濾層將其餘較小粒徑的粉塵及花粉等雜質予以濾除，可將空氣充分淨化後，再由引擎吸入來確保空氣與燃料能完全燃燒，而可避免導致引擎組件容易損壞，以延長引擎的使用壽命，並維持汽車的行駛性能。Therefore, when the air passes through the multifunctional engine room air filter, in addition to filtering the larger particle size dust in the air through the basic filter layer, the remaining smaller particle size dust and pollen impurities are also enhanced through the reinforced filter layer. Filtered out, the air can be fully purified, and then inhaled by the engine to ensure that the air and fuel can be completely burned, and the engine components can be easily damaged to prolong the service life of the engine and maintain the driving performance of the car.
