The air outlet 114 and the water discharge hole 113 are arranged in a staggered manner in the horizontal direction, which may mean that the central axis of the air outlet 114 and the central axis of the water discharge hole 113 are arranged in a staggered manner in the horizontal direction.

When the air filter assembly 10 is applied to a motorcycle, the air inlet pipe body 110 can be arranged at the lower left side of the helmet box, and can be vertically pressed with the helmet box and fixed on the frame by means of screwing, clamping and the like.

As shown in fig. 3 and 4, in one embodiment, the air inlet pipe body 110 has a windward side 115 inclined with respect to a horizontal plane, and the air inlet holes 112 are opened on the windward side 115. Therefore, when the motorcycle runs, more air collides with the windward side 115, more air can enter the air inlet cavity 111 through the air inlet holes 112, more air can enter the air cylinder, the air inlet amount is improved, and the combustion efficiency and the combustion condition are improved. The included angle between the windward side 115 and the horizontal plane can be flexibly designed or adjusted according to actual use conditions, and only the air entering the cylinder meets the combustion conditions.

As shown in fig. 2, in one embodiment, an opening groove 116 communicating with the intake chamber 111 is provided above the intake pipe body 110. The intake manifold assembly 100 also includes a cover 120. The cover 120 may be disposed on the opening groove 116 and partially opens the opening groove 116 to form the air inlet 112. Thus, the cover 120 is installed in the opening groove 116, and the air intake hole 112 is formed by a gap between the cover 120 and an inner wall of the opening groove 116. The cover 120 may be connected to the air inlet pipe body 110 in a clamping, inserting, or bonding manner, so that the cover 120 may be stably and reliably installed in the opening groove 116. The cover 120 may be plate-shaped or strip-shaped, and the specific shape may be flexibly designed or adjusted according to the shape and size of the opening slot 116. In addition, the cover 120 and the opening groove 116 are arranged, and the position of the air inlet hole 112 is correspondingly adjusted by adjusting the installation position of the cover 120 in the opening groove 116, so that the air inlet hole 112 can be arranged corresponding to the water discharge hole 113. Of course, in other embodiments, the cover body 120 may be covered in the opening groove 116, and the air inlet hole 112 is formed on the cover body 120; the air inlet hole 112 may also be formed by a gap between the cover body 120 and the inner wall of the opening groove 116, and meanwhile, the air inlet hole 112 is also formed on the cover body 120. It is only necessary to arrange the position of the air intake hole 112 corresponding to the water discharge hole 113.

As shown in fig. 4, further, the cover 120 is provided with a first guide sidewall 121 disposed corresponding to the air intake hole 112. The drain hole 113 has a second guide sidewall 1131.

In this way, the first guide side wall 121 and the second guide side wall 1131 which are arranged at intervals and are located on the same plane are used for guiding the water drops mixed in the air, so that the water drops can better fall into the drain hole 113; the dry air separated from the water droplets enters the air outlet holes 114 through the gap between the first guide sidewall 121 and the second guide sidewall 1131 and is discharged. Wherein, when the opening groove 116 is arranged on the windward side 115 which is arranged obliquely relative to the horizontal plane, the cover body 120 which is arranged in the opening groove 116 is also arranged obliquely relative to the horizontal plane, so that the first guide sidewall 121 and the second guide sidewall 1131 are disposed to be inclined with respect to the horizontal plane, the air mixed with the water drops enters the air inlet 112 to first collide with the first guide sidewall 121, so that a part of the water drops (which may be the water drops with lighter weight) adhere to the first guide sidewall 121 and gather into larger water drops, and then drop along the first guide sidewall 121 to the second guide sidewall 1131 under the action of gravity and are discharged from the water discharge hole 113, and another part of the water drops (which may be the water drops with heavier weight) drop directly under the action of gravity and are discharged from the water discharge hole 113, therefore, the separation effect of the water drops and the air is good, and the air discharged from the air outlet holes 114 is ensured not to be mixed with the water drops.

As shown in fig. 4, further, the drain hole 113 has a third guide sidewall 1132 connected to the second guide sidewall 1131. The third guide sidewall 1132 is disposed above the second guide sidewall 1131. The third guide sidewall 1132 is obliquely disposed toward the gas outlet hole 114 with respect to the second guide sidewall 1131. And, a projection of the lower end of the first guide sidewall 121 in the vertical direction falls on the third guide sidewall 1132. Like this, guarantee that the water droplet that drops from first direction lateral wall 121 drops to third direction lateral wall 1132 under the action of gravity on, the water droplet on third direction lateral wall 1132 flows to second direction lateral wall 1131 and finally flows out through wash port 113 along third direction lateral wall 1132 under the action of gravity, avoids the water droplet to drop to venthole 114.

A vertical distance (shown as D in fig. 4) between an upper end of the third guide sidewall 1132 and a plane of the first guide sidewall 121 is preferably within 50mm (which may be 10mm, 20mm, 30mm, 40mm, or 50mm), so that a water drop dropping from the first guide sidewall 121 can drop on the third guide sidewall 1132. The upper end of the third guide sidewall 1132 may be connected to the inner wall of the air outlet hole 114.

A vertical distance (as shown in H of fig. 4) between a line connecting the uppermost end of the third guide sidewall 1132 and the leftmost side of the air inlet 112 on the left side thereof and the lowermost end of the first guide sidewall 121 is preferably-15 mm to +15mm (which may be-15 mm, 0mm, or 15mm), so that dry air can smoothly enter the air outlet 114, and it is also ensured that water droplets dropping from the first guide sidewall 121 cannot mix with air again in the dropping process and can drop on the third guide sidewall 1132. It should be noted that, taking a connecting line between the uppermost end of the third guide sidewall 1132 and the leftmost side of the air inlet 112 on the left side thereof as a reference line, when the lowermost end of the first guide sidewall 121 is located above the connecting line, the vertical distance between the lowermost end of the first guide sidewall 121 and the connecting line is a positive value; when the lowermost end of the first guide sidewall 121 is located below the connection line, the vertical distance between the lowermost end of the first guide sidewall 121 and the connection line is negative.

When the amount of water droplets separated instantaneously is large, the water droplets are prevented from overflowing into the air outlet hole 114. As shown in fig. 1 and 2, in one embodiment, the air intake pipe assembly 100 further includes a water storage element 130, and the water storage element 130 is communicated with the water discharge hole 113. Thus, even if a large amount of water droplets are separated, the water droplets can be stored by the water storage function of the water storage element 130, and the water droplets are prevented from overflowing into the air outlet 114. The water storage element 130 may be a cavity-shaped water storage box with a large volume, and is made of plastic or rubber. The water storage element 130 may further be provided with a drain pipe to drain water periodically or in real time, and the diameter of the drain pipe may be set to be small to prevent foreign objects such as external dust from entering the water storage element 130 through the drain pipe. The water storage element 130 and the drainage hole 113 can be connected in a sealing manner by a sealing ring.

As shown in fig. 1 and 2, in one embodiment, the intake manifold assembly 100 further includes a filter element 140, the filter element 140 being disposed within the intake aperture 112. Thus, the filtering member 140 can filter the impurities with larger particles, and the impurities are prevented from blocking the drain hole 113 and the air outlet 114. The filtering member 140 may be a filtering net, a filtering screen, or other elements, and the filtering diameter thereof may be flexibly selected according to actual use requirements. The filter member 140 may be connected to the intake manifold body 110 by snap-fit, screw-fit, or the like so as to cover the intake port 112.

The number of the inlet holes 112 can be flexibly designed or selected according to the actual use requirement, and the number of the drain holes 113 and the number of the outlet holes 114 can be flexibly designed or selected accordingly, in order to meet the corresponding air intake amount.
