Referring to fig. 1 to 5, in an embodiment of the present invention, the expansion tank includes:
the expansion box body 1 is provided with a filling port 11; and
The utility model discloses technical scheme passes through 11 lids of filler of expansion box 1 are equipped with pressure release subassembly 2 to realize the sealed and pressure release of expansion tank. Specifically, the pressure relief assembly 2 is hollow and arranged to form a backflow chamber 21, the first pressure relief hole 22 is communicated with the inside of the expansion box body 1, the second pressure relief hole 23 is communicated with the outside of the expansion box body 1, when the coolant stored in the inside of the expansion box body 1 enters the backflow chamber 21 from the first pressure relief hole 22 along with the pressure relief process or overflows due to shaking of the vehicle body and enters the backflow chamber 21, the coolant stays in the backflow chamber 21 and finally flows back to the inside of the expansion box body 1 from the first pressure relief hole 22, and the second pressure relief hole 23 can smoothly relieve the pressure. In this embodiment, the pressure relief assembly 2 can smoothly relieve the pressure and also can smoothly return the coolant to the inside of the expansion tank 1. The pressure relief structure of the embodiment is simple, the number of parts is small, the production cost is greatly reduced, complicated equipment such as a valve body is not involved, and therefore the expansion tank formed by the pressure relief assembly 2 is more reliable.
Further, the pressure relief assembly 2 comprises a sealing element 24 and a cover 25 connected to each other, wherein the sealing element 24 and the cover 25 enclose the backflow cavity 21; the sealing element 24 is arranged at the filling port 11, and the sealing element 24 is provided with the first pressure relief hole 22; the cover body 25 is arranged at the filling opening 11 and above the sealing element 24, and the cover body 25 is provided with the second pressure relief hole 23.
In this embodiment, the sealing member 24 is detachably separated from the cover 25. In another embodiment, the sealing member 24 and the cover 25 may be integrally formed.
In an embodiment, the sealing member 24 is cup-shaped, a diameter of the sealing member 24 is gradually decreased downward along a height direction, and the first pressure relief hole 22 is disposed at a bottom of the sealing member 24. In this way, the cooling liquid in the interior of the return chamber 21 flows along the tapered side wall of the sealing member 24 to the bottom of the sealing member 24, and the cooling liquid can flow back to the interior of the expansion tank 1 from the first pressure relief hole 22 at the bottom of the sealing member 24.
In an embodiment, specifically, a fixing portion 241 is disposed at an edge of the sealing member 24, and the fixing portion 241 abuts against an edge of the filling port 11. The sealing member 24 abuts on the edge of the filler neck 11 via the fixing portion 241, so that the sealing member 24 can be disposed in the filler neck 11. However, the design is not limited thereto, in other embodiments, the sealing member 24 may be provided with a thread, and the sealing member 24 may be fixed to the filling port 11 by rotating, and in still other embodiments, the connection relationship between the sealing member 24 and the filling port 11 may be a snap-fit or other fixing manner.
