Precise and intelligent liquid pushing device

The utility model relates to the technical field of medical auxiliary liquid pushing devices, in particular to an accurate and intelligent liquid pushing device which comprises an assembly and a liquid storage bottle and further comprises a liquid pushing assembly, a driving assembly, an induction assembly and a control assembly, the execution end of the driving assembly is connected with the liquid pushing assembly in a meshed mode, and the control assembly is electrically connected with the induction assembly and the driving assembly. By arranging the first inductor, the second inductor and the third inductor, the operation states of the magnetic sensor and the liquid pushing rod can be accurately known, then the moving distance of the liquid pushing rod can be calculated according to relevant parameters, and therefore the accurate liquid pushing dosage can be calculated. And the push rod rack is in meshed connection with the transmission gear, so that the bottle plug of the liquid storage bottle is stably
