Detailed Description

In order to describe the technical content and constructional features of the present utility model in detail, the following description will be made with reference to the embodiments in conjunction with the accompanying drawings.

As shown in fig. 1 to 6, the tank 100 for a vehicle of the present utility model includes a tank body 10 and an all-in-one pipe assembly 20. The tank body 10 is provided with a liquid storage cavity 11, the top of the tank body 10 is provided with a mounting opening 12 communicated with the liquid storage cavity 11, and the side part of the tank body 10 is provided with a liquid injection joint 13 communicated with the liquid storage cavity 11. The arrangement of the liquid injection joint 13 facilitates the installation of a liquid injection pipe 26 which will be described later, and the first end of the liquid injection pipe 26 is abutted against the liquid injection joint 13. The liquid storage chamber 11 of the tank 10 is used for storing a solution, and in the present utility model, the stored solution is urea solution, but according to actual needs, the solution can also be used for storing oil or cooling liquid, so the type of the solution is not limited.

The all-in-one pipeline assembly 20 comprises a ventilation butt joint piece 21, a limiting pipe 22, an air inlet pipe 23 and an exhaust pipe 24. The ventilation docking 21 has spaced apart inlet and

outlet passages

211, 212 therein, and a first end of the inlet tube 23 communicates with a first end of the inlet passage 211. The limiting pipe 22 is installed in the ventilation butt joint piece 21, the limiting pipe 22 is communicated with the second end of the air outlet channel 212, the first end of the exhaust pipe 24 is communicated with the first end of the air outlet channel 212, and the waterproof ventilation structure 25 is installed in the air inlet channel 211. The ventilation butt joint piece 21 is installed at the installation opening 12 and connected to the box body 10 in a hot melt mode, and the limiting pipe 22 penetrates through the installation opening 12 and extends vertically downwards.

When urea solution is injected into the liquid storage cavity 11, the air pressure in the liquid storage cavity 11 is continuously increased along with the liquid injection, and the air in the liquid storage cavity 11 sequentially flows through the limiting pipe 22, the air outlet channel 212 and the air outlet pipe 24 along the solid arrow direction in fig. 3 and is finally discharged to the atmosphere, so that the air pressure in the liquid storage cavity 11 is balanced, and the liquid injection is normally performed. When the injected urea solution is about to overflow the limiting pipe 22, the liquid level of the solution is the position indicated by an arrow B in fig. 3, the air in the liquid storage cavity 11 cannot be discharged in time, the air pressure in the liquid storage cavity 11 changes, and the filling gun automatically stops filling after sensing. As shown in fig. 4, when in use, the urea solution in the liquid storage cavity 11 is continuously reduced, the air pressure in the liquid storage cavity 11 is reduced, and the air in the external environment flows into the liquid storage cavity 11 through the air inlet pipe 23 and the air inlet channel 211 to balance the air pressure of the liquid storage cavity 11, so that the normal use is avoided.

Because spacing pipe 22 installs in the butt joint piece 21 of ventilating, spacing pipe 22, intake pipe 23 and blast pipe 24 are assembled into an organic whole, and the integrated level is higher, and the structure is more concentrated, and spacing pipe 22 wears to locate the installing port 12 and vertical downwardly extending moreover, consequently box 10 need not set up the opening in addition and supplies spacing pipe 22 to install, and the hole site of box 10 is fewer, and the structural integrity of box 10 is better, reduces the processing and the equipment degree of difficulty, has also simplified the structure. In addition, the ventilation butt joint piece 21 is connected to the box body 10 in a hot melting mode, the ventilation butt joint piece 21 is tightly connected with the box body 10, and the risk of leakage of urea solution can be avoided.

In contrast, as shown in fig. 7, in the previous structure, the ventilation butt joint 21 ' is mounted on the tank 10 ' by the screw structure 211 ', the ventilation butt joint 21 ' is connected with the air inlet pipe 23 ', sealing is realized by the O-ring, the sealing effect is not ideal, and the urea solution is at risk of leakage. In addition, the previous limiting tube 22 ' is mounted on one side of the case 10 ' and not on the ventilation butt joint piece 21 ', and the case 10 ' needs to be perforated for mounting the limiting tube 22 '. It can be seen that the previous structure is more complex, the machining and mounting processes are more and the structure is more loose than the previous structure. The liquid injection joint 13 'is arranged beside the limiting pipe 22', the air supply and exhaust pipe 24 'of the limiting pipe 22' is in butt joint, and the liquid injection joint 13 'is in butt joint with the liquid supply and injection pipe 26'.

It should be noted that, during the liquid injection, part of the gas in the liquid storage cavity 11 will also pass through the waterproof and breathable structure 25 and then flow into the air inlet channel 211, and then be discharged to the external environment through the air inlet pipe 23, but the flow rate of the waterproof and breathable structure 25 (which is a waterproof and breathable film but not limited thereto) is very small, usually only 0.5-2L/min, and the rate of the solution injection is 20-40L/min, so that the air permeating through the waterproof and breathable film is not much, but mainly flows out through the air outlet channel 212. In normal operation, the urea solution is gradually consumed at a slower consumption rate, and at this time, the external air flows into the liquid storage cavity 11 through the waterproof breathable film to supplement air balance air pressure, and the ventilation amount of the waterproof breathable film is enough at 0.5-2L/min.

As shown in fig. 1 to 6, the ventilation docking member 21 includes a mounting seat 213, and an air inlet joint 214 and an air outlet joint 215 connected to the mounting seat 213, respectively. The first end of the air inlet pipe 23 is sleeved on the air inlet joint 214, and the first end of the air outlet pipe 24 is sleeved on the air outlet joint 215. The air inlet joint 214 facilitates the installation of the air inlet pipe 23, and the air outlet joint 215 facilitates the installation of the air outlet pipe 24. An O-ring is additionally arranged between the air inlet joint 214 and the air inlet pipe 23 to strengthen the sealing. The mounting seat 213 is a circular shell structure, one side of the bottom opening is connected to the box 10 by hot melt, the air inlet channel 211 is formed on the air inlet pipe 23 and the mounting seat 213, and the air outlet channel 212 is formed on the air outlet joint 215 and the mounting seat 213. The limiting tube 22 is mounted on the mounting seat 213 by means of hot melting, screwing, inserting and the like, and of course, the limiting tube 22 and the mounting seat 213 can be made into an integral structure according to actual needs, for example, an integral structure by injection molding.

As shown in fig. 1 to 6, the all-in-one pipeline assembly 20 of the present utility model further includes a filling pipe 26, and the exhaust pipe 24 is locked to the filling pipe 26. After the exhaust pipe 24 is locked on the liquid injection pipe 26, the two pipes are stably connected together, so that the structural stability is effectively improved. For example, the locking may take different forms, such as snaps, bindings, fasteners, and the like. The all-in-one line assembly 20 of the present utility model further includes a plug 27, the plug 27 being operable to openably and closably cover the second ends of the exhaust 24 and the fill tube 26. When the liquid is injected, the plug 27 is opened, the filling gun is inserted into the liquid injection pipe 26 to inject urea solution, at the moment, the exhaust pipe 24 is connected with the external atmosphere, after the liquid is injected, the plug 27 is closed, the liquid injection pipe 26 and the exhaust pipe 24 are closed, and the leakage of the solution and the pollution of the solution by external pollutants are avoided.

As shown in fig. 1 to 6, the air inlet pipe 23 has a bent structure, the air inlet pipe 23 includes a first section pipe 231 extending horizontally and a second section pipe 232 extending vertically and downwardly, the first section pipe 231 is located above the tank 10, the second section pipe 232 is attached to the side wall of the tank 10, the air inlet pipe 23 is not unfolded outwards, and the air inlet pipe 23 does not occupy excessive external space, so that the structure of the vehicle liquid storage tank 100 is more compact. Preferably, the second pipe 232 is fastened to the outer wall of the casing 10, so that the air inlet pipe 23 is integrally and stably mounted to the casing 10. Still further, the outer side wall of the case 10 is provided with a mounting groove 14 extending vertically downward, and the air inlet pipe 23 is fastened to the mounting groove 14, so that the air inlet pipe 23 is stably mounted on the case 10.

As shown in fig. 1 to 6, the exhaust pipe 24 has a bent structure, and the exhaust pipe 24 includes a third pipe 241 extending horizontally and a fourth pipe 242 extending upward while being bent, and the first pipe 231 and the third pipe 241 extend in the same direction. The fourth tube 242 and the filling tube 26 are bent upward in normal state, and the solution is difficult to flow upward. The fourth tube 242 is locked to the filler neck 26 by a snap-fit structure 243 to firmly connect the fourth tube 242 to the filler neck 26.
