Title: Urea water injection tube for automobile to prevent overflow
Inventor: JEONG YUL PIL
IPC: B67D7/02
Filed: 2021-02-12
Abstract: The present invention is to prevent overflow when urea water for a vehicle is injected, wherein urea water is used to convert nitrogen oxides (NOx) generated during incomplete combustion in vehicles or construction equipment using diesel engines into nitrogen (N2) and water, which are harmless to the human body. In general, when injecting urea water for a vehicle, the urea water is injected using a urea water injection gun similar to a fuel injection gun and using an injection tube in the shape of a corrugated tube. When a corrugated tube is used, an air pipe is installed to facilitate the injection of urea water in consideration of the inner pressure of a urea water tank but the injection amount of urea water cannot be grasped. Therefore, an overflow of urine water occurs depending on the position (upper, lower) of the air pipe or excessive urea water injection. The overflowing urea water contaminates a vehicle, and solidifies in white to adversely affect the aesthetics and to shorten the lifespan of the parts of the vehicle being in contact. For the purpose, the present invention uses a pressure difference between the inside of a urea water injection tank and a urea water barrel (drum), and uses the Bernoulli principle in which air inside the urea water tank moves to the urea water barrel using a Venturi tube inside the corrugated tube, thereby allowing the injection of urea water to be blocked by pressure if an appropriate injection amount is exceeded during the injection of urea water into a vehicle or construction equipment.

Abstract: The present invention relates to a system for discharging air flowing inside through a side window of a vehicle during driving. According to an embodiment of the present invention, the system for discharging air flowing inside through a side window of a vehicle during driving includes: an exhaust pipe connecting the inside and the outside of a vehicle to discharge air flowing inside the vehicle through the side window of the vehicle during the driving of the vehicle; and an exhaust door installed in the exhaust pipe to open the exhaust pipe when the air flows from the inside of the vehicle to the outside. An inner suction port of the exhaust pipe is positioned on the rear of a back seat of the vehicle and formed on an inner surface of the vehicle connected to a rear window of the vehicle. Therefore, the air flowing inside through the side window can be smoothly discharged to the outside even when the side window is open during driving. So, resistance due to wind is minimized, and fuel consumption according to the resistance of the wind can be minimized. Moreover, in an existing system for discharging air, the air flows inside half of the open space and flows outside to the half of the open space when the window of the vehicle is lowered during driving. But the system for discharging air flowing inside through a side window of a vehicle during driving can maximize air inflow effect as the air flows into the entire open space. Also, the system for discharging air flowing inside through a side window of a vehicle during driving can solve an existing problem of eddying as the air flows into a sealed interior of the vehicle during driving. Furthermore, the inner suction port of the exhaust pipe is positioned on the rear of the back seat of the vehicle and formed on the inner surface of the vehicle connected to the rear window of the vehicle. So, the air flowing downward along the rear window can easily flow into the inner suction port of the exhaust pipe formed on the inner surface of the vehicle connected to the rear window.
