Abstract

A liquid medicine sprayer comprises a sprayer body and an inner plug located in the sprayer body. A spray orifice is arranged at the head of the sprayer body, a liquid inlet channel is arranged on the inner plug, a primary turbulence region is arranged at the bottom of the liquid inlet channel, a liquid outlet is arranged on a side wall of the inner plug and corresponds to the primary turbulence region, the inner plug and the sprayer body form a cylindrical secondary turbulence region connected with the liquid outlet, a tertiary turbulence region is disposed between the top of the inner plug and the head of the sprayer body, and the secondary turbulence region is communicated with the tertiary turbulence region. The liquid medicine sprayer is simple in structure and low in manufacturing cost, and is easier to enter the nostril of an ill animal, liquid medicine can be sprayed out in a nebulizing manner, the diameters of drops of sprayed mist range from 50 micrometers to 80 micrometers, absorption of the liquid medicine is increased, immunity and treatment effects are guaranteed, comfortableness of the ill animal during treatment can be realized, and the possibility that the ill animal injures persons when the ill animal feels uncomfortable during treatment is avoided. In addition, the liquid medicine sprayer is used with a needle cylinder with graduations, metering of the liquid medicine can be controlled, and the liquid medicine sprayer is simple in operation and convenient in use.

Description

Technical field [0001] The invention relates to a spray device, in particular to a spray head for spraying liquid medicine. Background technique [0002] At present, veterinary nose drops are only dripped into the nostrils by means of squeezing a plastic bottle, etc., and there are many problems: First, it is difficult to operate during administration and the administration site is not accurate, especially for pigs; The second is that the amount of medicine cannot be measured when squeezed with a plastic bottle; the third is that there is no atomization effect, and the comfort and absorption of livestock are poor, which seriously affects the immune and therapeutic effects. The spraying device currently in use has many parts, complex structure, small sprayed water mist, poor atomization effect, and can not perform metered spraying of liquid. Summary of the invention [0003] Aiming at the disadvantages of the current drug release device, which is difficult to operate, inaccurate i...
