Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0023] See also Figures 1-4 The utility model provides a multifunctional urea filling machine overflow prevention device, including a controller 1, a connecting pipe 2 is fixed to the bottom of the controller 1 by bolts, a gun head 3 is fixed to one end of the connecting pipe 2 by bolts, the internal structure of the gun head 3 is the same as the refueling gun at a gas station, a tee pipe 10 is provided at one end of the tee pipe 10, a liquid outlet pipe 5 is provided at one end of the tee pipe 10, an air inlet 6 is provided on one side of the liquid outlet pipe 5, a liquid storage barrel 9 is fixedly connected to one side of the gun head 3 by a clamp, and the liquid storage barrel 9 is connected to one end of the tee pipe 10, and the interior of the tee pipe 10 is provided with a liquid flow direction control device. When the regulating mechanism is changed, the liquid outlet pipe 5 is placed in the urea tank of the vehicle, the filling amount is input through the controller 1, and then the urea liquid is added through the connecting pipe 2 and the gun head 3. During the filling process, the air in the urea tank will be discharged through the air inlet 6, so that the pressure in the urea tank tends to be constant. When the urea liquid in the urea tank is full, the urea liquid will block the air inlet 6, so that the gun head 3 no longer discharges liquid. At the same time, the liquid flow direction in the tee pipe 10 is changed, so that the urea liquid enters the liquid storage barrel 9, further preventing liquid from flowing out of the gun head 3.

[0024] In the present utility model, an input module, a processor and a dosage reminder module are provided in the controller 1. The processor is connected to the gun head 3 and the pump, and the dosage reminder module is connected to the processor. The input module is used to set the filling amount of urea liquid, and the filling amount of urea liquid can be input according to demand. The processor is used to process the signal transmitted by the gun head 3 and stop the operation of the pump in time to avoid urea overflow. The dosage reminder module is used to remind the staff and the driver of the filling amount this time. After the filling is completed, the filling amount will be voice broadcast.

[0025] Among them, the adjustment mechanism includes a baffle 13, which is rotatably connected to the top inner wall of the tee pipe 10. Two liquid troughs 11 are provided on the top of the tee pipe 10. The two liquid troughs 11 are respectively connected to the liquid storage barrel 9 and the liquid outlet pipe 5. A power mechanism for driving the baffle 13 to rotate is provided on the top of the gun head 3. The baffle 13 is driven by the power mechanism to rotate so that the baffle 13 blocks one of the liquid troughs 11, and the urea liquid can only be discharged through the other liquid trough 11, thereby completing the one-way selection of the urea liquid circulation and ensuring that the urea liquid will not overflow. The power mechanism includes a protective cover 4, which is screwed in. The bolt is fixed to one side of the gun head 3, and the top outer wall of the protective cover 4 is fixed with a motor by bolts. The output shaft of the motor is connected to the connecting shaft 12 through a flange, and one end of the connecting shaft 12 passes through the tee pipe 10 and is fixed to the baffle 13. When the motor is started, the motor drives the connecting shaft 12 to rotate, thereby driving the baffle 13 to rotate. There is no need to manually adjust the rotation position of the baffle 13, and the motor is connected to the processor, which can change the flow direction at a very fast speed, further reducing the amount of urea liquid flowing out of the gun head 3 when the urea tank is full, and offsetting the waste of urea liquid caused by inertia during urea liquid filling.

[0026] Among them, the circumferential outer wall of the gun head 3 is sleeved with a rubber cover 7, and the circumferential outer wall of the rubber cover 7 is provided with a locking component for fixing the position of the rubber cover 7. The locking component is preferably a clamp 8 and a rubber band. When the urea solution is added, the rubber cover 7 contacts the filling port of the urea tank, sealing the filling port of the urea tank to prevent urea from splashing out of the urea tank during the filling process, thereby improving the protection effect of the device.

[0027] The working principle and use process of the utility model are as follows: the amount of urea liquid to be added is input and set through the input module on the controller 1, the input module transmits the signal to the pump, the pump starts, and the external urea liquid flows into the connecting pipe 2, and then the liquid outlet pipe 5 is placed in the urea tank of the vehicle, and the switch at the gun head 3 is pinched to make the urea liquid flow out of the gun head 3 and flow into the urea tank. When the urea liquid is filled, the urea liquid will block the air inlet 6, and the gun head 3 will transmit the signal to the processing module, and the processing module The block transmits the signal to the pump and the motor to stop the pump and start the motor. The motor drives the connecting shaft 12 to rotate, thereby driving the baffle 13 to rotate, so that the baffle 13 blocks the liquid trough 11 connected to the liquid outlet pipe 5, and then the urea liquid with inertia enters the liquid storage barrel 9 from the other liquid trough 11, avoiding impact damage to the baffle 13. At the same time, the baffle 13 blocks the liquid trough 11 connected to the liquid outlet pipe 5, which prevents the urea liquid from flowing into the liquid outlet pipe 5, and prevents liquid from flowing out of the gun head 3.
