Roof anti-blocking water draining and air conveying composite floor drain

Abstract

The invention belongs to the field of building drainage devices, and relates to a roof anti-blocking water drainage and air conveying composite floor drain which comprises a floor drain body, a waterseal buckling bowl and a water filtering plate. A water storage cavity is formed in the floor drain body, the bottom of the floor drain body communicates with a drainage pipe, and the water seal buckling bowl is located between the drainage pipe and the water filtering plate and connected with the water filtering plate. A sewage discharging device is arranged in the floor drain body and comprisesa mud guiding annular plate and a mud gathering box, the mud guiding annular plate is placed on the bottom face of the floor drain body, the face, close to the water filtering plate, of the mud guiding annular plate is obliquely arranged, a notch is formed in the obliquely-downward end of the mud guiding annular plate, the mud gathering box is located at the bottom of the notch, and the notch communicates with the interior of the mud gathering box; and the mud gathering box is located at one side of the drainage pipe, and a mud inlet is formed in the drainage pipe and communicated with one side face of the mud gathering box. According to the roof anti-blocking water drainage and air conveying composite floor drain, impurities such as sludge, soil and sand deposited in the water storage cavity can be cleaned conveniently, odor is not likely to be generated in the water storage cavity of the floor drain, and the drainage pipe is not likely to be blocked.

Description

technical field [0001] The present application relates to the field of building drainage devices, in particular to a composite floor drain for roof anti-blocking and drainage. Background technique [0002] The floor drain is an important interface connecting the drainage system in the house and the indoor ground. The quality of the floor drain directly affects the indoor air quality. The common floor drain relies on water to form a water seal to separate the living space from the piping system. If the water seal of the floor drain loses its effect Or if the seal of the non-water-sealed floor drain is not tight, the sewer will not be separated from the indoor space, and the odor and toxic and harmful gases in the sewer will overflow along the pipeline and spread in the living room. [0003] The relevant announcement number is the Chinese utility model patent of CN201704750U, which discloses a high-clean double-sealed floor drain, including a floor drain main body, a water sea...
