[0022] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0023] Reference Figures 1-6 As shown, this utility model provides a technical solution: an automatic urea solution mixing device for vehicles, including a configuration device body 1. A dispensing mechanism 2 is installed at the front end of the configuration device body 1. A rotating column 3 is rotatably connected inside the dispensing mechanism 2. Adjustment grooves 4 are provided on both sides of the rotating column 3. A push block 5 is slidably connected inside the adjustment groove 4. An insertion rod 6 is fixedly connected to the side of the push block 5 near the inside of the adjustment groove 4. A dispensing pipe 7 is provided inside the rotating column 3. Insertion holes 8 are provided on both sides of the dispensing pipe 7. Arc blocks 9 are fixedly connected to both ends inside the dispensing mechanism 2. The operator inserts the dispensing pipe 7 into the inside of the rotating column 3 and rotates the rotating column 3. During the movement of the rotating column 3, the push block 5 and the insertion rod 6 are moved simultaneously. The operator makes the push block 5 contact the thicker end of the arc block 9, so that the thicker end of the arc block 9 pushes the push block 5 to drive the insertion rod 6 into the inside of the insertion hole 8, thereby achieving the function of installation and replacement.

[0024] Reference Figures 4-6 As shown in this embodiment, the size of the plug rod 6 is adapted to the size of the socket 8, and the surface of the plug rod 6 is inserted into the interior of the socket 8. By adapting the size of the plug rod 6 to the size of the socket 8, the plug rod 6 can be stably inserted into the interior of the socket 8, effectively improving the connection stability between the two.

[0025] Reference Figure 5 As shown in this embodiment: a storage spring 10 is fixedly connected to the side of the push block 5 near the insertion rod 6, and the side of the storage spring 10 away from the push block 5 is fixedly connected to the inside of the adjustment groove 4. When the operator uses the push block 5 to push the insertion rod 6, the push block 5 compresses the storage spring 10 to store force, and drives the insertion rod 6 to be inserted into the insertion hole 8, so that the liquid outlet tube 7 is limited. When the operator releases the limitation of the push block 5, the insertion rod 6 can be ejected from the insertion hole 8 under the action of the rebound force of the storage spring 10, so as to facilitate the operator to disassemble or replace the liquid outlet tube 7.

[0026] Reference Figure 5 As shown in this embodiment: sliding grooves 12 are provided on both sides of the inner side of the adjusting groove 4, and sliders 11 are fixedly connected to both sides of the push block 5. The surface of the slider 11 is slidably connected to the inside of the sliding groove 12. When the operator moves the push block 5, the push block 5 drives the slider 11 to slide inside the sliding groove 12. Through the above settings, the stability of the push block 5 during the movement can be effectively improved, and the position of the push block 5 can be avoided due to improper operation. At the same time, the sliding connection design between the slider 11 and the sliding groove 12 makes the push block 5 move more smoothly, reduces friction, and improves the overall operating efficiency.

[0027] Reference Figure 3 As shown in this embodiment: the inner wall of the liquid dispensing mechanism 2 is provided with two annular grooves 13, and two annular blocks 14 are fixedly connected to the outer diameter surface of the rotating column 3. The surface of the annular blocks 14 is slidably connected to the inside of the annular grooves 13. When the operator rotates the rotating column 3, the rotating column 3 drives the annular blocks 14 to slide inside the annular grooves 13. Through the above setting, the stability of the rotating column 3 during the rotation process can be effectively improved, and the position of the rotating column 3 can be avoided due to improper operation. At the same time, the sliding connection design between the annular blocks 14 and the annular grooves 13 also makes the rotating column 3 rotate more smoothly, reduces friction, and further improves the overall operating efficiency.

[0028] Reference Figure 3 As shown in this embodiment: a sealing gasket 15 is installed inside the liquid dispensing mechanism 2 on the side near the liquid dispensing pipe 7. By installing the sealing gasket 15 inside the liquid dispensing mechanism 2 on the side near the liquid dispensing pipe 7, the sealing between the liquid dispensing mechanism 2 and the liquid dispensing pipe 7 can be effectively improved, avoiding leakage of urea solution during the mixing process and ensuring the accuracy and stability of the mixing process.

[0029] Reference Figure 3 and Figure 5 As shown in this embodiment: both ends of the rotating column 3 are provided with shrinkage grooves 16, and an insertion block 17 is slidably connected inside the shrinkage groove 16. A return spring 18 is fixedly connected to the side of the insertion block 17 near the inside of the shrinkage groove 16, and the side of the return spring 18 away from the insertion block 17 is fixedly connected to the inside of the shrinkage groove 16. Insertion holes 21 are provided on both sides of the liquid dispensing mechanism 2. When the operator rotates the rotating column 3 to fully insert the insertion rod 6 into the insertion hole 8, the position of the shrinkage groove 16 is parallel to the insertion hole 21. At the same time, under the action of the return spring 18, the insertion block 17 is pushed, so that the insertion block 17 is limited to the insertion hole 21. Through the above settings, the rotating column 3 is prevented from rotating inside the liquid dispensing mechanism 2.

[0030] Reference Figure 5As shown in this embodiment: guide grooves 19 are provided at both ends of the shrinkage groove 16, and guide blocks 20 are fixedly connected to both ends of the insertion block 17. The surface of the guide block 20 is slidably connected to the inside of the guide groove 19. When the operator moves the insertion block 17 back and forth, the insertion block 17 drives the guide block 20 to slide inside the guide groove 19. Through the above settings, the stability of the insertion block 17 during the movement can be effectively improved, and the situation of the insertion block 17 shifting position due to improper operation can be avoided.

[0031] Working principle: The operator inserts the outlet tube 7 into the rotating column 3 and rotates the rotating column 3. During the movement of the rotating column 3, the push block 5 and the insertion rod 6 move simultaneously. The operator makes the push block 5 contact the thicker end of the arc block 9, causing the thicker end of the arc block 9 to push the push block 5, which in turn drives the insertion rod 6 into the insertion hole 8, achieving the purpose of installation and replacement. The size of the insertion rod 6 is matched with the size of the insertion hole 8, allowing the insertion rod 6 to be firmly inserted into the insertion hole 8, effectively improving the connection stability between the two. When the operator uses the push block 5 to push the insertion rod 6, the push block 5 compresses the energy storage spring 10 to store energy, and drives the insertion rod 6 into the insertion hole 8. Inside the socket 8, the outlet pipe 7 is limited. When the operator releases the push block 5, the insertion rod 6 can be ejected from the socket 8 under the action of the spring 10, making it convenient for the operator to disassemble or replace the outlet pipe 7. When the operator moves the push block 5, the push block 5 drives the slider 11 to slide inside the slide groove 12. Through the above settings, the stability of the push block 5 during movement can be effectively improved, avoiding the situation where the position of the push block 5 is deviated due to improper operation. At the same time, the sliding connection design between the slider 11 and the slide groove 12 makes the push block 5 move more smoothly, reduces friction, and improves the overall operating efficiency. When the operator rotates the rotating column 3, the rotating column 3 drives the ring block 14 to slide inside the annular groove 13. This design effectively improves the stability of the rotating column 3 during rotation, preventing positional deviation due to improper operation. Simultaneously, the sliding connection design between the ring block 14 and the annular groove 13 makes the rotation of the rotating column 3 smoother, reducing friction and further improving overall operational efficiency. The sealing gasket 15 installed inside the dispensing mechanism 2 near the dispensing pipe 7 effectively improves the sealing between the dispensing mechanism 2 and the dispensing pipe 7, preventing leakage of urea solution during the mixing process and ensuring accurate mixing. To ensure the accuracy and stability of the process, when the operator rotates the rotating column 3 to fully insert the insertion rod 6 into the insertion hole 8, the position of the contraction groove 16 is parallel to the insertion hole 21. At the same time, under the action of the return spring 18, the insertion block 17 is pushed, so that the insertion block 17 is limited to the insertion hole 21. Through the above settings, the rotating column 3 is prevented from rotating inside the liquid dispensing mechanism 2. When the operator moves the insertion block 17 back and forth, the insertion block 17 drives the guide block 20 to slide inside the guide groove 19. Through the above settings, the stability of the insertion block 17 during the movement can be effectively improved, and the position of the insertion block 17 is avoided due to improper operation.
