The first bolt position 54 is provided near the middle of the upper end face, and the second bolt position 52 is distributed at the corners of the upper end face. The air guide cover 5 is designed as a detachable connection structure, which can be replaced separately in the event of damage, saving costs.

[0033] Reference Figure 6As shown, the air inlet 8 is arranged upwardly and tilted, and the air inlet 8 is directly connected to the upper end surface of the filter element 6. The air outlet 7 is arranged vertically upward, and the air outlet 7 is connected to the side of the filter element 6 through the side space of the filter cavity.

[0034] A perforated plate 56 is horizontally arranged in the filter chamber. The filter tube constituting the filter element 6 is fixedly mounted on the hole slots on the perforated plate 56. A first row of miscellaneous holes 55 is opened near the corners of the perforated plate 56. The first row of miscellaneous holes 55 is located on one side of the air outlet 7 in the vertical direction.

[0035] An extension plate 57 is provided on one side of the orifice plate 56 close to the air outlet 7, and a second row of miscellaneous holes 53 is opened on the extension plate 57;

[0036] The first row of miscellaneous holes 55 and the second row of miscellaneous holes 53 are both connected to the inner cavity of the bottom shell 1. When the air filter element discharges air to the engine, the remaining liquid water and sand and dust are discharged from the first row of miscellaneous holes 55 and the second row of miscellaneous holes 53.

[0037] A guide plate 2 is installed on the inner side of the bottom shell 1, and a bottom plate 10 is provided at the bottom of the bottom shell 1;

[0038] The guide plate 2 is spaced apart from the bottom plate 10 and is fixedly connected to the inner wall of the bottom shell 1;

[0039] The guide plate 2 is a structure with four edges inclined downward toward the center, the middle of the guide plate 2 is the lowest point in the vertical direction, and a discharge port 21 is provided in the middle of the guide plate 2. Figure 4 As shown, the bottom plate of the bottom shell 1 is provided with a hole groove connected to the discharge port 21, and there are at least two discharge ports 21 and hole grooves. Figure 6 As shown, since the guide plate 2 is spaced apart from the bottom plate of the bottom shell 1, a hose connection hole is embedded in the discharge port 21 during actual use to prevent sand and dust from entering the gap. In addition, an elliptical recessed groove is provided in the middle of the bottom of the guide plate 2, and the discharge port 21 is arranged in the recessed groove. At least two discharge ports 21 are provided in parallel to improve the efficiency of water and sand removal.

[0040] In order to improve the structural strength, such as Figure 4 The outer surface of the bottom shell 1 is provided with a reinforcing rib structure. The reinforcing rib structure includes a grid-like reinforcing rib 12 provided on the bottom of the bottom plate of the bottom shell 1 and a strip-shaped reinforcing rib 11 provided on the side plate of the bottom shell 1.

[0041] Continue to refer to Figure 4 and Figure 5 As shown, a clamping block 3 is provided at the upper edge of the bottom shell 1 , and the clamping block 3 is used for detachably clamping with the upper shell 4 of the air filter.

[0042] Reference Figures 3 to 5As shown, the block 3 is provided with a slot 31, in which a metal buckle is inserted. The metal buckle includes a lower buckle 01, which is hinged to an upper buckle 02. The upper end of the upper buckle 02 is flipped and snapped onto the lower edge of the upper shell 4 of the air filter. Figure 5 The lower buckle 01 has two ends, one end is fixed in the slot 31, and the other end is in contact with the side of the bottom shell 1. The overall pre-tightening is achieved by utilizing the elasticity of the two sections of metal buckles. A combination of multiple blocks 3 and metal buckles is evenly arranged on the outer edge of the entire shell of the air filter to achieve a detachable connection.

[0043] Continue to refer to Figure 6 As shown, in this embodiment, the base plate 10 adopts a detachable connection structure. The base plate 10 is fixed to the bottom of the guide plate 2 by bolts 101. The contour edge of the base plate 10 abuts against the bottom shell 1. The base plate 10 is located at the bottom of the air filter and is easily damaged. When it is deformed, it can be removed and replaced, avoiding the loss caused by replacing the overall structure.
