detailed description

In order to make the technical problems, technical solutions and beneficial effects solved by the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

1 and 2, the utility model provides a jet aerator, including: a housing 1, an air inlet pipe 2, an air inlet chamber 3, an inlet pipe 4 and n jet pipes 5; wherein, n is Natural number;

The air intake duct 2 is arranged on the top of the housing 1, the top of the air intake duct 2 is an air inlet, and the bottom end is an exhaust port, and the exhaust port of the air intake duct 2 passes through the shell wall of the housing 1, and is arranged on the The air intake chamber 3 inside the housing 1 is in sealed communication;

The liquid inlet pipe 4 is arranged below the housing 1, the top end of the liquid inlet pipe 4 is a sealing structure, and the bottom end is a liquid inlet, and the top end of the liquid inlet pipe 4 passes through the shell wall of the housing 1 and extends to the bottom of the housing 1. Inside, and located below the intake chamber 3;

The periphery of housing 1 is provided with n jet tubes 5, and each jet tube 5 is all inclined downwards, and the top of each jet tube 5 passes through the shell wall of housing 1 and extends to the bottom of housing 1. Inside; in FIG. 1 , n is 6, and there are 6 jet tubes in total, and the housing is a regular hexagon, and each jet tube 5 is set on one side of the housing 1 .
