[0002] Traditional vehicle engine drainage systems often pose a risk of water backflowing into the vehicle during heavy rain or when driving through or parking on flooded roads. If water seeps into the engine compartment, it can even cause short circuits in the circuit boards, leading to vehicle breakdown, or in severe cases, spontaneous combustion. Therefore, solving the problem of water backflowing into the vehicle through the pipes is an urgent issue that needs to be addressed. Utility Model Content

[0003] To address the aforementioned problems in the existing technology, the purpose of this utility model is to provide a special-shaped water pipe for preventing backflow into a vehicle engine, comprising two special-shaped pipes arranged vertically. Each of the two pipes has an upper connector and a lower connector at opposite ends, which are connected to the pipes. The upper connector and the lower connector are sealed and connected by a connecting structure. A foam ball is placed between the connecting structure and the lower connector. The weight and volume of the foam ball are sufficient to allow it to float after backflow due to water accumulation and to seal the opening of the special-shaped pipe connected to the upper connector. A support structure for supporting the foam ball is provided inside the lower connector.

The upper end face of the annular protrusion 7 is connected to the lower end face of the upper connector 2, and the lower end face of the annular protrusion 7 is connected to the upper end face of the lower connector 3. The combined sealing connection of the connection structure is completed by covering the annular block 5 with glue.

[0008] The grooves, which are multiple in number, are formed on the lower end face of the annular block and cooperate with the supporting structure to complete the snap-fit.

[0009] As a preferred embodiment, the annular protrusion is provided with multiple sets of locking blocks integrally formed with the annular block and arranged in an array. The locking blocks are divided into upper inclined blocks and lower inclined blocks, which are respectively located on the upper end face and the lower end face of the annular protrusion.

[0020] The present invention will be further described below with reference to specific embodiments.

[0021] A special-shaped water pipe for preventing backflow in vehicle engines includes two irregularly shaped pipes 1 arranged vertically. The upper and lower ends of the two irregularly shaped pipes 1 are respectively provided with an upper connector 2 and a lower connector 3 connected to the irregularly shaped pipes 1. The upper connector 2 and the lower connector 3 are connected and sealed by a connecting structure. A foam ball 4 is provided between the connecting structure and the lower connector 3. The weight and volume of the foam ball 4 are sufficient to allow it to float after backflow of water and seal the opening of the irregularly shaped pipe 1 connected to the upper connector 2. A supporting structure for supporting the foam ball 4 is provided inside the lower connector 3.

[0022] It should be noted that the shape of the irregular tube 1 can be injection molded according to actual usage requirements.

[0023] Hollow foamed balls 4 are placed on the supporting structure of the lower connector 3, and then the upper connector 2 and the lower connector 3 are connected by connectors to complete the connection of the two irregular tubes 1 arranged vertically. After assembly, the whole thing is installed into the vehicle.

[0024] When the car is running normally and the water pressure is normal during drainage, the foam ball 4 will press against the supporting structure, which can keep the pipeline unobstructed and allow for normal drainage.

[0025] In heavy rain or water-related scenarios, the buoyancy generated by the foam ball 4 when water flows back into the lower connector 3 will cause the foam ball 4 to float up and block the pipe opening of the upper connector 2, thus blocking the backflow path and effectively preventing water from flowing back into the vehicle through the pipe.

[0026] In a preferred embodiment, the shaped tube 1, the upper connector 2, the lower connector 3, and the supporting structure disposed in the lower connector 3 are all made of rubber material, preferably corrosion-resistant rubber, which reduces weight while providing good sealing performance. The upper and lower shaped tubes 1 and the connector are integrally molded, which can reduce leakage points caused by multi-segment connections.

[0027] As a preferred embodiment, the connecting structure is made of a rigid material, preferably an engineering plastic, which can ensure structural rigidity and prevent deformation from causing the sealing connection to fail.

[0028] In a preferred embodiment, the connection structure includes:

[0029] The annular block 5 is located between the upper connector 2 and the lower connector 3. The annular block 5 encloses the foam ball 4, which can wrap the foam ball 4 and restrict its range of motion to prevent it from shifting.

[0030] The sealing truncated cone 6 is set on the upper end of the annular block 5 and is integrally formed with the annular block 5. It cooperates with the foam ball 4 and seals the pipe opening of the upper connector 2. The sealing truncated cone 6 can fit tightly with the inner wall of the upper connector 2 to avoid deformation of the upper connector 2 and affect the seal. At the same time, the arc structure of the inner wall of the sealing truncated cone 6 can fit with the surface of the foam ball 4 to form a hard sealing interface, which enhances the sealing performance during backflow.

[0031] Annular protrusion 7; The annular protrusion 7 is disposed around the outer side of the annular block 5 and is integrally formed with the annular block 5. The upper end face of the annular protrusion 7 is connected to the lower end face of the upper connector 2, and the lower end face of the annular protrusion 7 is connected to the upper end face of the lower connector 3. The combined sealing connection of the connection structure is completed by covering the annular block 5 with glue.

[0032] Multiple grooves 8 are formed on the lower end face of the annular block 5 and are engaged with the supporting structure to complete the snap-fit.

[0033] As a preferred embodiment, the annular protrusion 7 is provided with multiple sets of locking blocks 9 integrally formed with the annular block 5 and arranged in an array. The locking blocks 9 are divided into upper inclined blocks 91 and lower inclined blocks 92. The upper inclined blocks 91 and lower inclined blocks 92 are respectively provided on the upper end face and lower end face of the annular protrusion 7. The upper connector 2 and the lower connector 3 are provided with multiple slots 10 corresponding to the locking blocks 9 one by one.

[0034] During connection, align the slots 10 on the upper connector 2 and the lower connector 3 with the upper inclined block 91 and the lower inclined block 92 respectively to complete the snap-fit ​​and further enhance the stability of the connection.

[0035] As a preferred embodiment, the support structure includes:

[0036] Ribs 11, there are multiple ribs 11, which are arrayed on the inner wall of the lower connector 3 and are snapped into the grooves 8 one by one to ensure the axial stability of the connection structure.

[0037] Supporting blocks 12, multiple supporting blocks 12 are set one by one on the end face of each rib 11. The supporting surface of the supporting block 12 is set in an arc shape to facilitate supporting the foam ball 4. The arc surface of the supporting block 12 can fit with the bottom of the foam ball 4 to disperse the impact force of the water flow. The supporting block 12 and the rib 11 form a support grid to prevent the foam ball 4 from clogging the lower pipe opening.
