Description

Backflow preventing structure of boosting device of electronic injector Technical Field The invention relates to the technical field of electronic injectors, in particular to a backflow preventing structure of an electronic injector boosting device. Background The existing market water-light needle injection has commonly used a boosting device to be matched with a syringe and a needle for injection. The basic principle of the boosting device is that a negative pressure pump is utilized to generate suction force, so that the shell at the bottom of the hydro-optical needle head can adsorb skin at the area to be injected and generate a certain lifting effect, and meanwhile, a sensor in the main machine of the boosting device senses the change of air flow and transmits the air flow to a control unit, and the control unit gives out a corresponding injection instruction after receiving the information. The injection mode of the boosting device matched with the injector and the needle greatly improves the operation efficiency of doctors and the injection effect of the hydro-optical needle user, but the injection mode has obvious hidden trouble, the injection is difficult to be absorbed by the skin of the user completely in the injection process, part of injection can be influenced by the suction force of the negative pressure of the boosting device, the negative pressure pipe air channel of the boosting device enters the main engine of the boosting device, and the air channel of the boosting device is easy to be blocked, the electronic components in the boosting device are corroded and the circuit is short-circuited due to the abnormality of the air channel of the boosting device, and great influence is brought to the injection effect, the service life of the boosting device and the injection safety after long-term use or single injection quantity is overlarge.
