The invention discloses a liquid dropping
bottle with
bacteria-blocking and
oxygen-blocking dual protection functions, which comprises a
bottle body, a
composite film bag arranged in the
bottle body, a ventilation hole formed in the bottle body, a pump body arranged on the bottle body, a trigger movably arranged on the pump body, a liquid dropping column arranged on the trigger, and a first spring arranged in the pump body, the trigger abuts against the first spring, a pump core is arranged in the trigger, a one-way valve shaft is inserted in the pump core, a first ring groove is reserved between the one-way valve shaft and the pump core, a one-way valve plate is arranged on the one-way valve shaft, a pressure limiting deformation gap is reserved between the one-way valve plate and the one-way valve shaft, and a second spring is arranged in the one-way valve shaft. The second spring abuts against the one-way valve plate, and the one-way valve plate blocks the liquid outlet hole. The liquid dripping device can play a good role in resisting
oxygen and
bacteria during liquid dripping, and only quantitative liquid
medicine can be squeezed out no matter how much force is used for pressing the trigger, so that the liquid
medicine drips in the form of liquid drops and cannot be jetted.
