Description

Technical Field

[0001] This utility model belongs to the technical field of gasoline engine air filter technology, and relates to a detachable air filter. Background Technology

[0002] An engine air filter is a device that provides clean air to the engine. After a period of use, the filter element needs to be removed for cleaning and replacement. Most existing air filters are located on top of the crankcase and have a flat structure, which effectively reduces the overall height of the engine. However, when maintaining or replacing the filter element, both the top cover and the filter element are removed vertically along the engine. This can lead to difficulties in removing or installing the air filter, or even make it impossible, when space is limited at the top of the engine. Utility Model Content

[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a detachable air filter.

[0004] The objective of this utility model can be achieved through the following technical solution: a detachable air filter, including a base, a top cover slidably connected to the base, the base and the top cover combined to form a closed cavity, the base having an outwardly extending side, the bottom of the top cover having a right-angled wide edge, the right-angled wide edge having a bottom edge, the bottom edge and the right-angled wide edge forming a limiting groove matching the side, and a buckle structure for fixing the top cover being provided between the base and the top cover.

[0005] In the aforementioned detachable air filter, the base has side plates on both sides, and the buckle structure includes a buckle mounting seat on the side plate. The buckle mounting seat is hinged with a spring buckle, and the top cover has a buckle platform with a slot. The spring buckle can be snapped into the slot.

[0006] In the aforementioned detachable air filter, a limiting step is provided on the base, and when the upper cover is closed with the base, one end of the upper cover is located on the limiting step.

[0007] In the aforementioned detachable air filter, a positioning block is provided on the side of the top cover, and a positioning hole is provided on the side of the base near the top, the positioning hole matching the positioning block.

[0008] In the aforementioned detachable air filter, a pull plate is also provided on the wide side.

[0009] Compared with the prior art, this utility model achieves a sliding connection between the top cover and the base, allowing the top cover and filter element to be removed for maintenance and replacement even when space is limited on top of the engine, thus saving maintenance time.

[0017] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments. Example

[0018] like Figures 1 to 6 As shown, a detachable air filter includes a base 1, on which a limiting step 8 is provided. When the upper cover 2 is closed with the base 1, one end of the upper cover 2 is located on the limiting step 8, and the limiting step 8 provides support after the upper cover 2 and the base 1 are closed.

[0019] A top cover 2 is slidably connected to the base 1. The base 1 and the top cover 2 combine to form a closed cavity, which is used to install components such as filter elements. The base 1 has an outwardly extending side 3, and the bottom of the top cover 2 has a right-angled wide edge 4. The right-angled wide edge 4 has a bottom edge 5, and the bottom edge 5 and the right-angled wide edge 4 form a limiting groove 6 that matches the side 3. When installing the top cover 2, by inserting the side 3 on the base 1 into the limiting groove 6, the top cover 2 can slide along the side 3 toward the limiting step 8. This not only guides the sliding of the top cover 2 but also limits its vertical movement.

[0020] The base 1 has side plates 9 on both sides, and a buckle structure 7 for fixing the top cover 2 is provided between the base 1 and the top cover 2. In this embodiment, there are two buckle structures 7 on each side.

[0021] The buckle structure 7 includes a buckle mounting base 71 on the side plate 9, and a spring buckle 72 is hinged to the buckle mounting base 71. The upper cover 2 is provided with a buckle platform 73, and a buckle groove 74 is opened on the buckle platform 73. The spring buckle 72 can rotate upward and be snapped into the buckle groove 74.

[0022] The upper cover 2 has a positioning block 10 on its side 3, and the base 1 has a positioning hole 11 on its upper side, which matches the positioning block 10. By setting the positioning hole 11 and the positioning block 10, when the upper cover 2 slides onto the limiting step 8, the positioning block 10 can be disassembled into the positioning hole 11, thereby realizing the secondary positioning of the upper cover 2.

[0023] A pull plate 12 is also provided on the wide edge, which makes it easy for workers to pull the top cover 2 out of the base 1.

[0024] This utility model allows the upper cover 2 and the base 1 to be slidably connected, so that even when the space on top of the engine is limited, the upper cover 2 and the filter element can be removed for maintenance and replacement. The filter element and the upper cover 2 can also be installed on the base 1 later.

[0025] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
