The locomotive M includes a front section, a middle section, and a rear section. In front of the locomotive M, there are components such as a faucet 91, a front wheel 92, a directional light, a keyhole, and an air cleaner assembly 1. The middle part of the locomotive M is provided with components such as a power system 95, a seat cushion 94 and a tripod. The rear part of the locomotive M is provided with components such as a taillight, a rear wheel 93, and a fender.

The faucet 91 is used to control the traveling direction of the locomotive M, and the faucet 91 can be equipped with functional parts, including a meter, a switch, a rear view mirror and the like. The faucet 91 also has a handle (including a fuel grip) and a handbrake. The user can control the steering of the faucet 91 through the handle, adjust the throttle angle of the power system 95 through the fuel grip to control the power output, and drive the locomotive M through the handbrake. slow down. The main light can also be installed on the faucet 91, and the main light provides the main light illumination for the locomotive M.

The faucet 91 and the front wheel 92 are interlocked by the faucet rotating shaft, whereby the angle of the front wheel 92 can be controlled by the rotating faucet 91, thereby controlling the traveling direction of the locomotive M.

The power system 95 connects and drives the rear wheel 93, thereby powering the locomotive M to advance the locomotive M.

The frame 96 extends from the front section of the locomotive M to the rear section, and the air cleaner assembly 1 is suspended above the frame 96.

Referring to Figures 2A and 2B, which show the three-dimensional structure of the air cleaner assembly 1 of the presently-created embodiment, the air cleaner assembly 1 includes a housing 10. The housing 10 is composed of a body 101 and an outer cover 102. An air inlet 11 is formed on the housing 10, and the housing 10 includes a first shielding wall 21 and a second shielding wall 22. The first shielding wall 21 is disposed on one of the first sides 111 of the air inlet. The second shielding wall 22 is disposed on the second side 112 of the air inlet 11 , and the second shielding wall 22 is connected to the first shielding wall 21 to form an L-shaped cross section.

Fig. 3A is a front view showing the air cleaner assembly 1 of the present embodiment, and Fig. 3B is a cross-sectional view showing the 3B-3B' direction in Fig. 3A. Referring to FIGS. 3A and 3B, the first shielding wall 21 includes a first segment 211 and a second segment 212. The first segment 211 extends toward a first direction X. The second segment 212 and the second segment 212 An angle θ is formed between the first directions X, and the angle θ is greater than 0 degrees.

Referring to Figure 3B, in one embodiment, the included angle θ is between 15 degrees and 45 degrees. In this embodiment, the included angle θ is 30 degrees. With the design of the first segment portion 211 and the second segment portion 212 described above, the water droplet W splashed outside is sucked by the suction port 11 without moving upward along the inner wall of the second segment portion 212 based on the action of gravity. Therefore, the problem that the water droplet W is sucked in by the suction port 11 can be avoided. The above range of angles is only an example and does not limit the creation. In general, in a different design, when the angle θ is too small, the function of preventing the water droplet W from being sucked may not be sufficiently provided, and when the angle θ is excessively large, the eddy current may be generated and the air intake effect may be lowered because the aperture ratio is lowered. However, the above situation still changes due to environmental parameters. For example, when the air cleaner assembly is tilted, even if the angle θ is small, it is possible to provide a function of preventing the water droplet W from being sucked. For another example, when the peripheral structure is less blocked, even if the angle θ is large, it is possible to provide a sufficient air intake effect.

Referring to Figures 1, 2A, and 2B, the air cleaner assembly 1 is fixed to the frame 96 of the locomotive, and the second shielding wall 12 corresponds to the frame 96. In an embodiment, the air inlet 11 is rectangular, and the air inlet 11 further includes a third side 113 and a fourth side 114. The third side 113 is parallel to the first side 111, and the fourth side The first side 113 and the fourth side 114 are in an open configuration, and are not provided with a structure corresponding to the first shielding wall or the second shielding wall. In other words, a notch N is formed and corresponds to the first shielding retaining wall and the second shielding retaining wall.

Referring to Figures 2A and 2B, in the embodiment of the present invention, the housing 10 further includes a main chamber 12, the main chamber 12 includes a cavity outdoor wall 121, and the cavity exterior wall 121 is partially formed therein. The third side 113 of the suction port 11. Referring to Figures 3A and 3B, after the airflow A enters the air intake port 11, it follows the flow path inside the casing 10 and passes through the filter core. After 31, the vent tube 32 is introduced into the main chamber 12 to provide a throttle to the locomotive. In Fig. 3A, a portion of the area is cut with a cut line C1 to show the flow path within the housing 10.

Referring to FIGS. 2B and 3A , in this embodiment, the housing 10 further includes a shielding portion 13 disposed on the third side 113 and protruding into the flow path of the air inlet 11 . A water guiding groove 131 extends from the side of the shielding portion 13 along the cavity outer wall 121. Through the design of the shielding portion 13 and the water guiding groove 131, the externally splashed water droplets are blocked by the shielding portion 13 and are led out by the water guiding groove 131, so that water accumulation does not occur.

Referring to FIG. 2A, in an embodiment, the air cleaner assembly 1 further includes a locking support portion 40. The locking support portion 40 is disposed on the housing 10, and the locking support portion 40 is locked. Attached to the frame 96, the lock support portion 40 is located between the frame 96 and the fourth side 114 of the suction port 11.

Referring to FIG. 4A, in an embodiment, the locking support portion 40 includes a projection 41 located between the frame 96 and the fourth side 114 of the suction port 11, in other words The projection 41 corresponds to the notch N, whereby the water retaining effect can be further provided. In an embodiment, the shielding length d1 of the protruding portion 41 is smaller than the shielding length d2 of the first shielding retaining wall 21 . This provides a water retaining effect and reduces interference with the airflow. Referring to FIG. 4B, in another embodiment, the projection 41 can include a plurality of vent openings 42. Similarly, the venting opening 42 reduces interference with airflow.

Applying the air cleaner assembly of the present embodiment, since the first side of the air inlet has a first shielding retaining wall to provide a water retaining function, the second side of the air inlet has a second shielding retaining wall to provide a water retaining function. The third side of the air inlet has a cavity outdoor wall to provide a water retaining function, and the fourth side of the air inlet has a frame to provide a water retaining function. Therefore, it can be adequately prevented Water droplets or dust are drawn into the air inlet. In addition, the third side and the fourth side of the air inlet are of an open structure, and no structure corresponding to the first shielding wall or the second shielding wall is provided. In other words, the notch is formed on the third side and the fourth side of the air inlet, and corresponds to the first shielding retaining wall and the second shielding retaining wall. Thereby, it is possible to prevent the intake pressure of the intake port from being excessively large and to suck in water droplets, and at the same time, maintain good intake efficiency. In a variation of the present invention, the locking support portion may further include a protruding portion to further provide a water retaining function.

Although the present invention has been disclosed in the above preferred embodiments, it is not intended to limit the present invention, and anyone skilled in the art can make some modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of this creation is subject to the definition of the scope of the patent application attached.
