Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-4 The utility model provides a technical solution: an energy-saving electromagnetic drive device for a urea solution electromagnetic valve, comprising a housing 1, a pressing fastener 10 welded inside the housing 1, and a first buckle groove 11 and a second buckle groove 12 formed on the surface of the pressing fastener 10;

[0025] A pressing body 7 is provided inside the pressing fastener 10, a plurality of limiting rods 8 are welded on the surface of the pressing body 7, and an inverted V-shaped sliding groove 9 is provided on the bottom surface of the pressing body 7;

[0026] The pressing body 7 is internally mounted with a magnetic shaft 13, and the surface of the magnetic shaft 13 is provided with buckle blocks 14 at equal distances in a circular array;

[0027] A connecting rod 15 is mounted on one end of the magnetic block shaft 13 . A baffle 17 is welded to one end of the connecting rod 15 . A protrusion 18 is provided on the surface of the baffle 17 .

[0028] Specifically, a mechanical emergency start button 6 is provided on the top of the pressing body 7, and a mechanical emergency start safety pin 4 is inserted on the surface of the mechanical emergency start button 6. One end of the mechanical emergency start safety pin 4 passes through the shell 1 and the mechanical emergency start button 6. There are multiple inverted V-shaped slide grooves 9, and multiple inverted V-shaped slide grooves 9 are arranged in a circular array on the surface of the pressing body 7. Multiple limit rods 8 are welded in a circumferential array on the surface of the pressing body 7. There are multiple first buckle grooves 11 and second buckle grooves 12. The first buckle grooves 11 and the second buckle grooves 12 are both arranged in a circumferential array on the surface of the pressing fastener 10. By pulling out the mechanical emergency start safety pin 4 from the surface of the mechanical emergency start button 5 and the shell 1, and by pressing the mechanical emergency start button 4, the pressing body 7 and the iron core shaft 13 are moved downward, and the limit rod 8 slides inside the first buckle groove 11 to limit the pressing body 7. To prevent the pressing body 7 from sliding out of the pressing fastener 10, the buckle block 14 slides along the shape of the first buckle groove 11 and the second buckle groove 12 on the surface of the pressing fastener 10. When the buckle block 14 slides into the second buckle groove 12, the connecting rod 15 moves down, compressing the spring 16, moving the baffle 17 and the protrusion 18 downward, and puncturing the diaphragm at the outlet of the urea solution container. When the urea solution container valve needs to be closed, the mechanical emergency start button 6 is pressed again to move the pressing body 7 and the iron core shaft 13 downward, and the buckle block 14 slides along the first buckle groove 11 on the surface of the pressing fastener 10 due to the shape of the second buckle groove 12. When the buckle block 14 slides into the first buckle groove 11, one end of the buckle block 14 contacts the inverted V-shaped slideway 9 at the bottom of the pressing body 7, and the connecting rod 15 and the baffle 17 move up, blocking the baffle 17 at the outlet of the urea solution container valve, thereby closing the urea solution container valve.

The electromagnetic driver safety pin 3 is pulled out from the connecting rod 15 and the surface of the shell 1, and the external power supply is connected through the starting circuit 2. The iron core rotating shaft 13 is moved downward by the magnetic force of the iron core, thereby moving the connecting rod 15 downward, compressing the spring 16, and moving the baffle 17 and the protrusion 18 downward. The diaphragm at the outlet of the urea solution container can be punctured by the protrusion 18, and the urea solution is discharged from the urea solution container valve.

[0030] The working principle of the utility model is as follows: all electrical equipment of the device are powered by an external power supply, the device is installed on the urea solution container valve through the mounting thread 5, and the baffle 17 is blocked at the outlet of the urea solution container valve. After installation, the electromagnetic drive safety pin 3 is pulled out from the surface of the connecting rod 15 and the shell 1, and the external power supply is connected through the starting route 2. The iron core rotating shaft 13 is moved downward by the magnetic force of the iron core, thereby moving the connecting rod 15 downward, compressing the spring 16, and moving the baffle 17 and the protrusion 18 downward. The diaphragm at the outlet of the urea solution container can be punctured by the protrusion 18, and the urea solution is discharged from the urea solution container valve. When there is no power supply, the mechanical emergency starting safety pin 4 is pulled out from the mechanical emergency starting button 5 and the surface of the shell 1, and the mechanical emergency starting button 4 is pressed to make the pressing body 7 and the iron core rotating shaft 13 move downward, and the limiting rod 8 is in the first buckle groove 11. When the urea solution container valve needs to be closed, the mechanical emergency start button 6 is pressed again to move the pressing body 7 and the iron core rotating shaft 13 downward. The buckle block 14 slides along the shape of the first buckle groove 11 and the second buckle groove 12 on the surface of the pressing fastener 10. When the buckle block 14 slides into the second buckle groove 12, the connecting rod 15 moves downward, the spring 16 is compressed, the baffle 17 and the protrusion 18 move downward, and the diaphragm at the outlet of the urea solution container is punctured. When the urea solution container valve needs to be closed, the mechanical emergency start button 6 is pressed again to move the pressing body 7 and the iron core rotating shaft 13 downward. The buckle block 14 slides along the shape of the first buckle groove 11 on the surface of the pressing fastener 10 due to the shape of the second buckle groove 12. When the buckle block 14 slides into the first buckle groove 11, one end of the buckle block 14 contacts the inverted V-shaped slideway 9 at the bottom of the pressing body 7, and the connecting rod 15 and the baffle 17 move upward to block the baffle 17 at the outlet of the urea solution container valve, thereby closing the urea solution container valve.
