The device comprises a circular tube body 1, a tube cavity partition plate 11, a 111 annular groove, a 112 water drainage hole, a concave table 12, a protrusion 13, a check valve assembly 2, a fixing ring 21, a guide tube 22, ribs 23, a valve core 24, a quincuncial hole 241, a sealing ring 25, a spring 26, a water inlet tube 3 and a water outlet tube 4.

Detailed Description

The present invention will be further described with reference to the following specific embodiments.

As shown in fig. 1-6, the device for deodorizing, preventing insects and preventing water from returning to sewage comprises a circular tube body 1, wherein the inner wall of the circular tube body 1 extends towards the axis to form a circular tube cavity partition 11, a sewage hole 112 is formed in the center of the tube cavity partition 11, an annular groove 111 is formed in the top surface of the tube cavity partition 11 close to the edge of the inner wall of the circular tube body 1, a check valve assembly 2 for limiting air or water to move from bottom to top is arranged in the circular tube body 1 below the tube cavity partition 11, and the check valve assembly 2 can realize the opening and closing of the sewage hole 112; the check valve component 2 comprises a fixed ring 21 fixed on the inner wall of a circular tube body 1, a guide tube 22 is arranged at the center of the fixed ring 21, the guide tube 22 is connected with the fixed ring 21 through ribs 23, the guide tube 22 is coaxially arranged with the circular tube body 1, a valve core 24 capable of moving up and down along the axial direction of the guide tube 22 is sleeved on the guide tube 22, the valve core 24 realizes the opening and closing of a lower water hole 112 through the up-and-down movement of the valve core 24, the valve core 24 is connected on the guide tube 22 in a sliding manner through a spring 26, a concave table 12 is processed on the inner wall of the circular tube body 1 at the installation position of the fixed ring 21, a bulge 13 is arranged on the concave table 12 and below the fixed ring 21, the lower water hole 112 at the center of a tube cavity clapboard 11 is processed into a funnel shape and is wide at the upper part and narrow at the lower part, the top of the valve core 24 is processed, the plum blossom hole 241 is sleeved on the guide tube 22, one end of the spring 26 props against the guide tube 22, and the other end props against the plum blossom hole 241.
