New description: [New technical field] This paper is about an air filter, especially an air filter β suitable for the intake system of a locomotive engine. [Prior Art] For general motor vehicles, The air intake system of the engine is usually provided with an air filter for filtering the outside air and making it clean air, and then introducing the clean air into the carburetor of the engine. Please refer to FIG. 1 for an exploded view of a conventional air cleaner. The air filter 90 of the conventional Skoda locomotive is composed of a left casing 91 and a right casing 93, which are combined with each other. A filter unit 92 is provided, which is fixedly coupled by a filter paper 94 and a fixed frame 95 into an integrated structure, and the outside air enters through the air inlet 911 of the left casing 91 of the air cleaner 90, and flows through After the filter paper 94 passes through the air outlet 93 of the right casing 93 and enters the carburetor of the engine (not shown) via an air outlet 96, the left casing 91, the right casing 93 and the filtering unit 92 are Multiple bolts 97 are locked and fixed The structure of the air cleaner 90 style. However, the position of the conventional air filter 90 is usually fixed to the upper part of the locomotive transmission and the lower side of the frame and between the left side of the storage box and the inner side of the appearance member. The conventional air filter 90 is used for repairing and replacing the filter paper 94. The plurality of bolts 97 must be removed by the tool, and the left casing 91 and the filter unit 92 are taken out to the outside. Since the above space of the locomotive is limited, the air filter is subject to three restrictions in the configuration. The following disadvantages are caused: The 9G is covered by the appearance piece on the inner side thereof, and the bolt 97 cannot be directly removed during maintenance and disassembly, that is, the left shell (4) and the over-feed element 92 cannot be directly taken out, and the secret personnel need to disassemble the appearance part before the bolt 97 can be removed, resulting in Maintenance is not easy, time-consuming and laborious. In addition, considering the configuration of the bolt 97 and the maintenance disassembly path, it may be necessary to reduce the space occupied by the air cleaner 9 ,, resulting in the overall volume of the air filter 90 being too small, which may affect the intake air amount, thereby affecting engine performance. Not very ideal, there is still room for improvement. Because of this, in the spirit of active invention, I thought about an air filter for the locomotive engine air intake system that can solve the above problems. After several research experiments, I completed this creation. [New content] The main purpose of this creation is to provide an air filter for the locomotive engine air intake system, so that the maintenance and disassembly path of the air filter will not be blocked by the appearance of the locomotive, and the maintenance and disassembly can be improved. 'Saves manpower and man-hours, and can maintain the overall space of the air filter, without affecting the intake air volume and affecting engine performance. The air filter of the locomotive engine air intake system of the present invention comprises: a hollow casing and a filter unit. The hollow housing includes an air inlet, an air outlet, a content chamber and an assembly opening, and the filter unit includes a filter member and a frame for fixing the filter member, and the filter unit passes through the hollow housing. The assembly opening is detachably assembled in the content chamber of the hollow housing. Also, M418970, that is, the shouting unit of the present invention can be a structure of the body by means of pulling out, and the structure of the above-mentioned passing piece and the frame can be a two-piece structure, and then fixedly combined to form a filtering unit. The frame of the above-mentioned passing unit may have a through hole, and the hollow casing has a screw hole corresponding thereto, so that the filter unit can be screwed to the hollow casing by a plurality of screw members. Further, the filter unit can be fixed to the hollow casing by means of snapping or other means of fixing the joint. The hollow housing may include a first housing and a second housing, and the first housing and the second housing may be in a body configuration. In addition, the first housing and the first housing may also be a two-piece structure, which is then fixed by ultrasonic welding. The filter element can be filter paper or other equivalent filter material, which can filter the air. The assembly opening of the hollow casing may be located at the rear side of the hollow casing so that the maintenance and disassembly path of the filter unit is not blocked by the appearance of the side of the locomotive. The air outlet of the hollow housing may be located in the first housing, and the air inlet of the hollow housing may be located in the second housing. In addition, the bottom of the second casing may have a leak port for draining rainwater flowing from the intake port. The air filter of the present invention can be assembled above the transmission room of the locomotive engine', and can also be set up elsewhere, as long as the assembly opening of the hollow casing of the air filter and its traveling path are not blocked by other components of the locomotive, Can achieve the effect of this creation. 5 M418970 [Embodiment] Please refer to FIG. 2 'FIG. 3 and FIG. 4' respectively for an exploded view of the preferred embodiment, an exploded view of the hollow casing and the filter unit, and a perspective view of a preferred embodiment. .
