Brief description of the drawings
The utility model is specifically described below with reference to accompanying drawing and with reference to example, the advantages of the utility model and realization
Mode will be more obvious, and content is only used for explanation of the present utility model wherein shown in accompanying drawing, without forming to this reality
With it is new in all senses on limitation, in the accompanying drawings：
Fig. 1 is one of the utility model embodiment schematic diagram；
Fig. 2 is two schematic diagrames of the utility model embodiment.
Embodiment
As shown in figure 1, the utility model automobile urea liquid automatic matching device, including agitator tank 11, water intaking valve 12, control
Device 13, the bottom of agitator tank 11 are provided with weighing sensor 14, and control device 13 connects water intaking valve 12 and weighing sensor respectively
14.According to embodiment of the present utility model, display input block that control device 13 includes being sequentially connected, control unit and weigh
Signal gathering unit, control unit connection water intaking valve 12, weighing-up wave collecting unit connection weighing sensor 14.In agitator tank 11
Ejector (Venturi nozzle) 15 is provided with, is provided with mixing pump 16 outside agitator tank 11, ejector 15 and mixing pump 16 are urinated
The stir process of plain liquid, control unit connection mixing pump 16.As shown in Fig. 2 the another way that the utility model is stirred
It is that the top of agitator tank 11 is provided with stirring motor 17, stirring motor 17 connects the agitating paddle 18 in agitator tank, the peripheral hardware of agitator tank 11
It is equipped with solution transfer pump 23, control unit connection stirring motor 17 and solution transfer pump 23.According to embodiment of the present utility model,
The charging aperture edge of agitator tank 11 is provided with proximity switch 19 and door 20, control unit connection proximity switch 19.The utility model
