The invention relates to a liquid ejection device for a vehicle wash facility, comprising a storage volume (4, 204), a first supply line (1, 101, 201) which is coupled to the storage volume (4, 204) upstream thereof for supplying a first liquid, a supply unit (222) which is coupled to the storage volume (4, 204) upstream thereof for supplying a second liquid, and a removal line which is coupled to the storage volume (4, 204) downstream thereof for discharging the liquid to be ejected, comprising a blocking device (15, 215) for blocking a flow of liquid through the removal line. In the device, the storage volume (4, 204) is closed in a gas-tight manner such that when liquid is introduced, the internal gas pressure in the storage volume (4, 204) increases. Furthermore, the liquid ejection device has a detection unit (231) for detecting the volume of the second liquid supplied into the storage volume (4, 204) and the internal gas pressure in the storage volume (4, 204), and a control unit (230) which is coupled to the detection unit (231) and the supply unit (222) controls the supply of the second liquid using the detected supplied volume of the second liquid and the internal gas pressure such that a specified mixture ratio of the first and second liquid is achieved in the storage volume (4, 204).
本发明涉及一种用于车辆清洗设备的液体喷射设备,所述液体喷射设备具有:储存体积(4,204);在上游与储存体积(4,204)耦联的第一输送管路(1,101,201),所述第一输送管路用于输送第一液体;在上游与储存体积(4,204)耦联的输送单元(222),所述输送单元用于输送第二液体;以及在下游与储存体积(4,204)耦联的排出管路,所述排出管路用于导出待喷射的液体,所述排出管路具有用于截止通过排出管路的液体流的截止装置(15,215)。在所述设备中,储存体积(4,204)气密式封闭,使得在导入液体时引起储存体积(4,204)中的气体内部压力增加。液体喷射设备还包括检测单元(231),所述检测单元用于检测输入到储存体积(4,204)中的第二液体的体积以及储存体积(4,204)中的气体内部压力,并且与检测单元(231)和输送单元(222)耦联的控制单元(230)根据检测到的所输入的第二液体的体积和气体内部压力来控制第二液体的输送,使得在储存体积(4,204)中达到第一液体和第二液体的预设混合比例。
