Abstract

A drip irrigation apparatus and system. The drip irrigation apparatus includes a flow channel body and an elastic body. The elastic body is mounted on the outer circumference of the flow channel body and fitted in a spontaneous state to the outer circumference of the flow channel body. The flow channel body includes an energy dissipation body. The first drainage channel is formed in the energy dissipation body, the first drainage channel is connected to both ends of the energy dissipation body. The first drainage channel is connected at both ends of the first drainage channel to the inner wall of the elastic body forming a radial drainage channel.

First claim

The invention claimed is:

1. A drip irrigation irrigator, comprising:
a flow channel body;
an elastic body, the elastic body being mounted on an outer periphery of the flow channel body and fitting to the outer periphery of the flow channel body the flow channel body comprising an energy dissipation body, the energy dissipation body having a first drainage channel, the first drainage channel being connected to a first end and a second end of the energy dissipation body, the energy dissipation body being connected at a first end and a second end of the first drainage channel with an inner wall of the elastic body to form a radial drainage channel;
the energy dissipation body having annular projections at the first and second ends, the annular projections extending along a circumference of the energy dissipation body, the elastic body having two ends set on the annular projections;
an outer sleeve, the outer sleeve being set outside the elastic body;
the energy dissipation body also having a first flow channel tooth set, a second flow channel tooth set and a set of support ribs, the first flow channel tooth set comprising a plurality of flow channel teeth, the second flow channel tooth set comprising a plurality of flow channel teeth, respective flow channel teeth of the first flow channel tooth set and the second flow channel tooth set being staggered and spaced apart;
the first flow channel tooth set and the second flow channel tooth set forming a first drainage channel between the first flow channel tooth set and the second flow channel tooth set, respective flow channel teeth of the first flow channel tooth set being connected by the support ribs, respective flow channel teeth of the second flow channel tooth set being connected by the support ribs;
the first drainage channel extending from the circumference of the energy dissipation body on a first side of the two support ribs to the circumference of the energy dissipation body on an opposite side of the two support ribs;
the energy dissipation body comprising a tube section, the tube section being located at the two ends of the first drainage channel and having a radial opening, the radial opening being located between the annular projections at the first end of the energy dissipation body and the annular projections at the second end of the energy dissipation body, forming a radial drainage channel;
the energy dissipation body comprising a first insertion section at one end in a water discharge direction, and the flow channel body further comprising an outlet component, an end of the outlet component facing the energy dissipation body having a second insertion section, the first insertion section being inserted into the second insertion section, and an end face of the second insertion section resting against the elastic body;
the flow channel body further comprising an inlet component, the inlet component comprising an inlet grille and a first drip irrigation adhesive surface, the inlet grille facing radially towards the flow channel body, and the first drip irrigation adhesive surface and the inlet grille being located on opposite sides of the inlet component; and
the flow channel body further comprising an outlet component, the outlet component having a second drip irrigation adhesive surface, the second drip irrigation adhesive surface being oriented opposite the first drip irrigation adhesive surface.

2. A drip irrigation system comprising the drip irrigation irrigator according to claim 1 .
