Detailed Description
As shown in fig. 1, which is a schematic view of the overall structure of the negative pressure pipe connector, the product includes a main body 1, an overflow protection device 2 and a connecting pipeline 3; the structural form of each component and the connection relationship between the components are described below.
Wherein, the tank body 1-1 is a cylindrical thin-wall knot.
The upper cover 1-2 is a cylindrical thin-wall stepped structure, a boss connected with the tank body 1-1 is arranged at the lower end of the bottom surface, cylinders with hollow structures are arranged on two sides of the top surface and are respectively connected with the air inlet pipe 3-1 and the air outlet pipe 3-2, circular protruding reinforcing ribs are arranged on the bottom surfaces of the cylinders connected with the air outlet pipe 3-2, a cylinder with a hollow structure is arranged in the middle of the top surface, and circular through holes are formed in the circumference of the inner side of the cylinder.
