Detailed Description

The present invention will be described in detail with reference to the accompanying drawings.

As shown in fig. 1-2, the horizontal canister with a hydrops chamber in this embodiment includes a canister body 1, a hydrops box 2 disposed at the rear side of the canister body 1, and a mounting bracket 3 disposed at the upper side of the canister body 1, a liquid accumulation cavity 21 is arranged inside the liquid accumulation box 2, an active carbon containing cavity 11 is arranged inside the carbon tank main body 1, the rear part of the liquid accumulation box 2 is provided with a first air inlet 22 which protrudes backwards from the liquid accumulation box 2, the first air inlet 22 can enable the liquid accumulation cavity 21 to be communicated with the outside, the rear part of the carbon tank main body 1 is provided with a second air inlet 12 which protrudes backwards from the carbon tank main body 1 and extends into the liquid accumulation box 2, the second gas inlet 12 enables the active carbon containing cavity 11 and the liquid accumulation cavity 21 to be communicated, the position of the second intake port 12 in the up-down direction is higher than the position of the first intake port 22 in the up-down direction. Still provide a mounting structure of horizontal canister with hydrops chamber in this embodiment, include oil tank 6, connecting line 7 and the horizontal canister that has the hydrops chamber, be provided with breather valve 61 on the oil tank 6, the head and the tail both ends of connecting line 7 are connected with breather valve 61 and first air inlet 22 respectively, both sides are connected with automobile body floor 5 through a plurality of bolts 4 respectively around installing support 3, and corresponding position is provided with a plurality of prewelding nuts on automobile body floor 5, is connected with a plurality of prewelding nuts respectively through a plurality of bolts 4, realizes transversely putting carbon tank main part 1 at automobile body floor 5's downside. When the gasoline vapor in the oil tank 6 volatilizes, the gasoline vapor enters the liquid accumulation cavity 21 through the vent valve 61, the connecting pipeline 7 and the first air inlet 22 in sequence, and finally enters the active carbon containing cavity 11 through the second air inlet 12. When the vehicle is driving, because breather valve 61 is higher than first air inlet 22 position in the upper and lower direction in the position of going up and down, along with the jolt of vehicle, the petrol of oil tank 6 takes place great rocking, can have a small amount of liquid petrol at rocking in-process through breather valve 61 via connecting line 7 and first air inlet 22 flow to hydrops chamber 21, prevent that liquid petrol from getting into in the active carbon holds the chamber 11 and leading to the active carbon to lose the adsorption function to prevent that the carbon canister from becoming invalid. Moreover, after the liquid gasoline enters the liquid accumulation cavity 21, the liquid gasoline is accumulated at the lower part of the liquid accumulation cavity 21 under the action of gravity, the position of the second air inlet 12 in the vertical direction is higher than the position of the first air inlet 22 in the vertical direction, the liquid gasoline in the liquid accumulation cavity 21 cannot enter the activated carbon containing cavity 11 through the second air inlet 12 before submerging the first air inlet 22, so that the liquid gasoline can be prevented from directly flowing into the activated carbon containing cavity 11, the liquid gasoline in the liquid accumulation cavity 21 can also be prevented from flowing into the activated carbon containing cavity 11 when shaking, and the gasoline in the liquid accumulation cavity 21 can finally volatilize to enter the activated carbon containing cavity 11, so that the oil storage effect is good, and the reliability is high.

In this embodiment, as shown in fig. 2, the axis of the first air inlet 22 is along the front-back direction, the liquid level of the liquid gasoline in the hydropneumatic chamber 21 is parallel to the front-back direction, and the axis of the first air inlet 22 can rise on the liquid level of the liquid gasoline along the front-back direction, so as to ensure that the liquid gasoline can flow back to the connecting pipeline 7 in time, and further ensure that the liquid gasoline in the hydropneumatic chamber 21 does not submerge the second air inlet 12.

In the present embodiment, as shown in fig. 2, the first inlet port 22 is located at the middle of the rear portion of the hydropneumatic tank 2, the second inlet port 12 is located at the upper portion of the rear portion of the canister body 1, and the liquid gasoline is first accumulated in the lower portion of the hydropneumatic chamber 21, so that the arrangement of the first inlet port 22 and the second inlet port 12 at the above positions ensures a sufficient volume in the lower portion of the hydropneumatic chamber 21.

In this embodiment, as shown in fig. 2 to 3, the cross section of the second air inlet 12 is rectangular, and the length of the second air inlet 12 in the vertical direction is smaller than the length of the second air inlet 12 in the horizontal direction. Because the liquid level of liquid petrol slowly rises from bottom to top, be in the volume of the lower part of guaranteeing hydropneumatic chamber 21 and guarantee under the consideration of the position of first air inlet 22, the length of second air inlet 12 in the up-down direction should choose for use less value, and the cross-section size of second air inlet 12 influences the efficiency that petrol steam got into active carbon and holds chamber 11 simultaneously, consequently should choose for use great value in order to guarantee cross sectional area second air inlet 12 length in the left and right directions.

Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
