Example 1

Referring to fig. 1-5, the injector with the medicine grinding function provided by the utility model comprises a needle cylinder 10, wherein a water outlet pipe 11 is fixedly arranged at the bottom end of the needle cylinder 10, a piston push rod 20 is movably arranged on the inner wall of the needle cylinder 10, a piston head 21 is fixedly connected to the bottom wall of the piston push rod 20, and a medicine grinding head 22 is fixedly connected to the bottom wall of the piston head 21; wherein, the shape of the medicine grinding head 22 is matched with the shape of the inner wall of the bottom of the needle cylinder 10 and the inner wall of the water outlet pipe 11, so that the tablets can be sufficiently ground.

As shown in figure 2 of the drawings,

a threaded block 23 is fixedly arranged on the top side wall of the piston push rod 20, a threaded sleeve 24 is fixedly connected to the top wall of the needle cylinder 10, and the threaded block 23 is in threaded connection with the inner wall of the threaded sleeve 24;

in order to achieve labor-saving medicine grinding, the thread blocks 23 and the thread sleeves 24 are arranged, when medicine grinding is performed, only the thread blocks 23 are required to be rotated, and threads on the inner walls of the thread blocks 23 and the thread sleeves 24 are meshed to drive the medicine grinding heads 22 to move, so that medicine grinding is completed.

As shown in figures 2 and 5 of the drawings,

the inner wall of the water outlet pipe 11 is provided with an internal thread, and the bottom thread of the water outlet pipe 11 is connected with a threaded rod 12;

wherein, when grinding, the bottom of the water outlet pipe 11 can be sealed by the threaded rod 12, thereby avoiding the powder from falling from the water outlet pipe 11.

A rubber layer 13 is arranged on the bottom side wall of the threaded rod 12; wherein, the rubber layer 13 that sets up makes between the outer wall of threaded rod 12 and the inner wall of outlet pipe 11 be sealing connection, leads to the liquid medicine to drop from the inside of outlet pipe 11 to cause the waste when avoiding follow-up rocking mixed liquid medicine.

As shown in figures 2 and 4 of the drawings,

the side wall of the needle cylinder 10 is fixedly connected with a water inlet pipe 31, a valve body 32 is arranged on the water inlet pipe 31, the inner wall of the valve body 32 is slidably connected with a valve core 33, a through hole 35 communicated with the outer wall of the valve core 33 is formed in the valve core 33, and a rotating block 34 is fixedly connected to the top wall of the valve core 33;
