In addition, it is to be understood that the elements of the invention may be combined in any suitable manner.

An aspect of the utility model relates to an use buffering kettle device of taking anti-overflow backward flow function in vehicle cooling system to optimize the spatial arrangement and the cost control of overflow backward flow system among the current vehicle cooling system.

As shown in fig. 1-4, an exemplary vehicle cooling system buffer pot 1 comprises a pot body 11 and an overflow spout 13, wherein the pot body 11 has an interior space therein (not visible in the drawings) for receiving a fluid, and the fluid flows into the interior space of the pot body 11 through the overflow spout 13, for example, from a power system component connected to the pot body 11 through the overflow spout 13 into the interior space of the pot body 11. Typically, the kettle body 11 comprises an upper kettle body and a lower kettle body, and the overflow spout 13 may be disposed on the upper kettle body. In some embodiments, the upper body and the lower body of the buffer kettle 1 can be connected by hot plate welding to form a complete kettle body, and a threaded spout structure connected with the cooling liquid kettle cover and one or more overflow nozzles (power system overflow pipe connectors) 13 can be respectively arranged on the upper body. The overflow pipe and the external connecting port can be designed according to the design form of the port piece and the butt joint requirement.

Formed in spout 13 are a smaller inner diameter d1 proximate to inlet 130 of spout 13 and a larger inner diameter d2 proximate to the interior space of kettle body 11. A one-way flow limiting structure 15 is also arranged in the overflow nozzle 13, and the one-way flow limiting structure 15 comprises a flow blocking ball 151. When fluid is to flow into the inner space of the kettle body 11 through the spout 13, the ball 151 is pushed into the portion of the spout 13 with the larger inner diameter d2, so that the spout 13 is in a through-flow state, and when fluid is to flow out of the inner space of the kettle body 11 through the spout 13, the ball 151 is pushed into the spout 13 close to the smaller inner diameter d1, so as to block the smaller inner diameter d1, so that the spout 13 is in a flow-blocking state. The smaller inner diameter d1 may be made smaller than the diameter of blocker ball 151 and the larger inner diameter d2 may be made larger than the diameter of blocker ball 151.

In some embodiments, a diameter-expanding portion 131 having an inner diameter gradually increasing from d1 to d2 is formed in the overflow lip 13 between the smaller inner diameter d1 and the larger inner diameter d 2.

Through the design that the inner diameter of the near inlet is small and the inner diameter of the far inlet is large, the inner flow channel of the overflow nozzle is designed into a diffusion pipe structure, so that the pressure of fluid when the fluid enters the inner space of the kettle body 11 through the overflow nozzle 13 is small, the overflow fluid under the normal working condition can enter the buffer kettle 1, and the normal flow of the fluid in the pipeline can be facilitated.

In some embodiments, the one-way flow-limiting structure 15 further comprises a stop lever 152 and a positioning spring 153 connecting the ball 151 and the stop lever 152, wherein the ball 151 is located relatively closer to the inlet 130 of the spout 13 and the stop lever 152 is located relatively closer to the inner space of the kettle body 11. Thus, when fluid is to flow into the interior of the kettle body 11 through the spout 13, the fluid pushes against the ball 151 and thus against the stop 152 via the positioning spring 153, and when fluid is to flow out of the interior of the kettle body 11 through the spout 13, the fluid pushes against the stop 152 and thus against the ball 151 via the positioning spring 153.

By means of the ball 151, the stop lever 152, the positioning spring 153 and the internal design of the overflow lip 13, a one-way flow-limiting function is provided in the overflow lip 13, i.e. fluid is allowed to flow in and fluid is prevented from flowing out. In addition, the choke ball 151 and the stop lever 152 are connected by the positioning spring 153, which ensures the correct switching of the choke ball 151 between the flow-passing position and the choke position, and increases the operational stability of the device.

In some embodiments, the check ball 151 and the stop lever 152 are made of a hydrolysis-resistant plastic material, and the positioning spring 153 is made of a stainless steel material resistant to corrosion of the coolant, so as to ensure the working stability and corrosion resistance of the structure.

In some embodiments, a stiffener structure may also be provided at the connection of the exterior of the spout 13 to the kettle body 11, and the stiffener structure may include one or more reinforcing ribs 132 extending axially parallel to the spout 13. In some embodiments, a spout protection structure 133 is also provided around the periphery of the spout 13, and the protection structure 133 may be a hollow cylinder structure or a half hollow cylinder structure surrounding the spout 13.

Another aspect of the present invention relates to a vehicle comprising the buffer pot apparatus, which can be used in a cooling system of the vehicle.

By using the buffering kettle device with the anti-overflow backflow function, the overflow backflow can be prevented without independently arranging a one-way valve, and the difficulty in arrangement of a cooling pipeline of the whole vehicle is reduced.

The foregoing specific embodiments are provided so that this disclosure will be thorough and complete, and will not be limited to these specific embodiments. It will be understood by those skilled in the art that various changes, substitutions and alterations can be made herein without departing from the spirit of the invention.
