Abstract

The invention discloses a novel downspout fitting which comprises a vertical downspout and a return water prevention component arranged in the downspout, wherein the return water prevention component comprises a vertical through barrel; the lower end of the barrel is articulated with an odor isolation plate for sealing a lower outlet of the barrel; a balancing weight is arranged at one end of the odor isolation plate; the odor isolation plate can rotate by the gravity action of the balancing weight; a motion space of the balancing weight is arranged above the balancing weight; a water blocking plate is arranged at the lower end of the barrel; the water blocking plate is positioned above the odor isolation plate; the water blocking plate is inclined from the top down from the balancing weight side of the odor isolation plate to the other side of the odor isolation plate; a lower water outlet is defined by the lower end of the water blocking plate and the lower end of the barrel; and the lower end of the water blocking plate is flush with the undermost end of the barrel. The downspout fitting can realize moth-proof, odor prevention and overflow prevention, and is more sanitary to use.

Description

technical field [0001] The invention relates to a water falling fitting. Background technique [0002] The main form of the existing water fittings is the downspout, and the disadvantages of the existing water fittings are that they do not have the functions of preventing insects, deodorizing and preventing overflow. Contents of the invention [0003] In order to overcome the above-mentioned shortcomings of the existing drain fittings, the present invention provides a novel drain assembly capable of preventing insects, deodorizing, and overflowing water. [0004] The technical solution of the present invention to solve the technical problem is: a new type of downwater fittings, including a vertical downpipe, and an anti-backwater assembly arranged in the downpipe, and the anti-backwater assembly includes a vertically penetrating Cylinder, the lower end of the cylinder is hinged with an odor barrier for closing the lower outlet of the cylinder, and one end of the odor barr...
