When the hose body is screwed up with the outer cover shell, the inner bushing and the necking pipe are both positioned in the outer cover shell, and partial emulsion can be accumulated at the liquid outlet of the necking pipe and the hose body when the hose body is placed upside down, so that the whole gravity center is inclined to the outer cover shell, and the whole hose assembly is more stable when the hose assembly is placed upside down.

Furthermore, the upper end of the thimble is a plum blossom-shaped flat plate part which is abutted against the upper end surface of the lining sleeve. The outer cover shell is screwed down, the lower end of the thimble can seal the outlet of the necking pipe, and meanwhile, the flat plate part is attached to the inner bushing, so that the whole thimble is firm and does not shake.

Furthermore, the cross section of the upper end of the outer cover shell is square, and the cross section of the lower end of the outer cover shell is circular. The outer cover shell in the shape is not easy to topple, the upper end face of the outer cover shell is a supporting face and is square, and the supporting area is large, so that the whole hose assembly is not easy to topple.

Furthermore, a plurality of annular grooves are formed in the inner side of the liquid outlet of the hose body, a plurality of annular convex strips are arranged at the lower end of the necking pipe, and the annular convex strips are clamped and embedded in the annular grooves. The liquid outlet of throat pipe and hose body is the joint, simple to operate, and the leakproofness is better simultaneously.

Furthermore, an annular step II is arranged on the gasket, and the lower end of the outer cover shell abuts against the annular step II.

Furthermore, the upper end of the inner bushing is provided with a vertically arranged strip-shaped clamping groove, and the inner side of the outer cover shell is provided with a protruding clamping strip which can be clamped into the strip-shaped clamping groove. When the outer cover shell is sleeved outside the inner lining, the clamping strip is also clamped into the strip-shaped clamping groove, and the inner lining also synchronously rotates when the outer cover shell is rotated.

Compared with the prior art, this first tooth plastic hose subassembly has following advantage:

1. the spare part compact structure, firm in connection, the leakproofness is good, and each spare part can also form a complete set and change.

2. The center of gravity of the whole hose assembly is concentrated in the outer cover shell, the center of gravity is downward when the hose assembly is placed upside down, and the supporting surface of the outer cover shell is large, so that the hose assembly can be stably placed and is not easy to topple.
