[0017] The application will be described in detail below with reference to the accompanying drawings. Figs. 1-3 The application will be described in detail below with reference to the accompanying drawings.
[0018] The utility model provides a multifunctional trigger device of electric animal needleless injector to solve the technical defects of single function of the trigger device of the prior art electric needleless injector. Figs. 1-3 As shown in the figure, the utility model can be implemented in the following manner; including shell 1, liquid storage cavity 2, nozzle sleeve spring 3, sealing tube 4, nozzle base 5, nozzle 6, nozzle sleeve 7.
[0019] On the liquid storage cavity, the surface facing the nozzle sleeve has an electronic element, which is a hall sensor, and sends a signal to drive the motor behind after detecting metal.
[0020] Function one, the bottom surface of the nozzle sleeve is made of metal material, and the nozzle sleeve is bounced back to the original position by the nozzle sleeve spring after moving to the right to trigger the hall device, completing a shot.
[0021] Function two, the front end of the nozzle sleeve is rounded and wavy, which can be directly pressed on the animal skin without scratching and irritating the animal, and when the nozzle sleeve moves backward to the position of the triggerable hall, the top end of the wavy line just coincides with the top end of the nozzle, which can ensure that the nozzle is just on the animal skin.
[0022] Function three, the nozzle sleeve has four vertical planes inside, which are the same as and parallel to the corresponding positions of the nozzle base Fig. 2 , Fig. 3 The nozzle base and the internal sealing tube and liquid storage cavity are all screw connected, and the nozzle base and the machine can be separated by the nozzle sleeve.
[0023] Compared with the prior art, the utility model has the following beneficial effects:
[0024] The multifunctional trigger device of the electric animal needleless injector provides three more optimized functions:
