[0006] Further, the branch pipe, the medicament pipeline and the limiting groove are integrally formed, and the inner wall of the medicament pipeline protrudes radially at the limiting groove for the filter pipe to extend into.

[0007] Further, the top end of the limiting groove protrudes towards the axis and has a limiting protrusion for clamping the rubber sleeve, and the limiting protrusion is recessed inward and has an annular groove for clamping the annular rubber sleeve.

[0008] Further, the filter pipe is composed of a filter screen, a limiting ring, a connecting rod and a connecting ring, two groups of limiting rings are provided and connected by a plurality of connecting rods between the two groups of limiting rings, the connecting rod is sleeved and fixed with the coaxially arranged connecting ring, the connecting ring is arranged at intervals along the length direction of the connecting rod, the filter screen is embedded and fixed between the limiting ring, the connecting ring and the connecting rod, and the rubber sleeve is sleeved on the limiting ring.

[0009] Further, the two groups of limiting rings, i.e. the two ends of the filter pipe, are sleeved with rubber sleeves.

[0010] Further, the inner wall of the plug near the opening is provided with an internal thread for screwing with an external thread, and the bottom of the plug is coaxially provided with a limiting plug ring for clamping the rubber sleeve at the bottom of the limiting ring.

[0011] Further, the plug is made of transparent material.

[0012] Compared with the prior art, the utility model has the advantages that the top of the filter pipe is abutted on the arc-shaped pad, so that the impurity particles and the like can be effectively prevented from passing through the gap at the top, the branch pipe and the filter pipe are arranged to effectively block the large particles and collect the large particles in the branch pipe under the sedimentation effect, the transparent plug can better observe the state of the internal filter screen, the overall structure is simple, convenient to replace, and the medicine feeding pipeline is effectively prevented from being blocked.
