[0022] In the present application, the rotating end of the motor 2 is connected to the rotating worm 16, and the motor 2 rotates to drive the rotating worm 16, and at the same time, the push rod bearing 17 moves along the spiral groove of the rotating worm 16, pulling the push rod 18 and the push rod spring 4 to compress. The push rod spring 4 is located on the push rod 18.
[0023] The operation process of the utility model is described below in conjunction with the accompanying drawings;
[0024] This patent provides a more preferred solution to solve the existing problem of trade-off between safety and cost: an electric needle-free injector for veterinary use. The solution is as follows:
[0025] The needle-free veterinary syringe described in the present invention has a Hall sensor element in the liquid storage chamber 6. The nozzle part 7 includes: a nozzle 11, a Hall sensor element 12, a nozzle spring 13, a front half of the liquid storage chamber 14, and a nozzle sleeve 15.
[0026] The motor motion chamber 3 includes: a rotating worm 16 , a push rod bearing 17 , and a push rod 18 .
[0027] Specific operation mode: Driving part: First, connect the syringe medicine bottle outside the machine from the medicine tube interface 8, and after starting up the machine through the built-in battery, control the motor 2 to rotate, drive the rotating worm 16, and at the same time, the push rod bearing 17 moves along the spiral groove of the rotating worm 16, pulling the push rod 18 and the push rod spring 4 to compress. The program controls the motor to rotate to a fixed angle and then stop. At this time, the intersection of the rotating worm 16 and the push rod bearing 17 is the highest point of the worm spiral groove ( Figure 4 , the arrow in the figure indicates the direction of rotation), at this time, the spring baffle 9 extends out, clamps the compressed push rod spring, and then the motor rotates a certain angle again until the push rod bearing 17 is suspended ( Figure 5 ).
[0028] When the Hall sensor at the front end gives a signal (the triggering method is described below), the spring baffle 9 retracts, and the compressed push rod spring 4 is released instantly, thereby pushing the push rod 18 and the liquid in the liquid storage chamber 6 to be ejected from the nozzle 11.
[0029] Trigger device: There is a cylindrical Hall sensor element in the liquid storage chamber 6. When the machine is pressed on the surface of the animal, the nozzle sleeve 15 will be pressed down to the liquid storage chamber 6 because the front end has a section higher than the nozzle. After it is completely fitted, the Hall device will send a signal to the signal adapter board 10, and then the adapter board will control the rear motor to rotate, causing the push rod bearing 9 mentioned in the previous paragraph to cross the highest critical point and the spring baffle to enter and exit, thereby releasing the spring to allow the push rod to fire the liquid. Then the nozzle sleeve 15 will reset due to its internal spring, and the motor will automatically rotate to the highest point and be clamped to wait for the next Hall device signal.
[0030] This patent has the following beneficial effects: 1. No need to waste a lot of needles for injection, saving costs. 2. Save time, after the control is started, you only need to press to inject the liquid. 3. Higher safety, no slender physical needle, no risk of accidental injury, the nozzle sleeve and software control play a double insurance role, usually no liquid will be sprayed out.
[0031] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
