Floor drain with anti-plugging, anti-backflow water seal and insert-and-pull type installation structure

Abstract

The invention discloses a floor drain with anti-plugging, anti-backflow, water seal and an insert-and-pull installation structure. The floor drain mainly includes a water collecting tank and a drainage pipe installed in a middle hole of the water collecting tank; the bottom of the drainage pipe is fixedly connected with a water storage cap with an opening upwards, and the water storage cap communicates with the lower part of the drainage pipe; an annular cover plate is connected with the drainage pipe located at the upper end port of the water storage cap in a sleeving mode; the annular coverplate can cover the upper end port of the water storage space precisely under the actions of no water pressure and self-weight or self-elasticity; and under the action of the water pressure, the jointpart of the annular cover plate and the water storage space is opened to enable water to flow out. The floor drain with anti-plugging, anti-backflow, water seal and an insert-and-pull installation structure has the advantages of plugging and back-irrigation proofing, good water sealing effect, simple structure, and easy installation and maintenance.

Description

technical field [0001] The invention relates to a floor drain, in particular to a floor drain with an anti-clogging, anti-backfilling, water-tight and plug-in installation structure. Background technique [0002] The floor drain is a large-scale and wide-ranging underground drainage device commonly used in places such as buildings, halls, and family houses. The number is very large, but these products or technologies have more or less defects such as complex structure, difficult installation and maintenance, poor sealing effect, easy backfilling, and easy blockage. For example: Chinese patent application number is 201720014780.4, The authorized announcement number is CN 207048005 U, and the name is "new anti-odor and anti-clogging floor drain". The high thing is, if the U-shaped tube is made of metal tube blanks, special equipment is required for bending. If the U-shaped tube is made of metal or non-metallic material, and the manufacturing process of mold molding is used, t...

Problems solved by technology

[0002] The floor drain is a large-scale and wide-ranging underground drainage device commonly used in places such as buildings, halls, and family houses. The number is very large, but these products or technologies have more or less defects such as complex structure, difficult installation and maintenance, poor sealing effect, easy backfilling, and easy blockage. For example: Chinese patent application number is 201720014780.4, The authorized announcement number is CN 207048005 U, and the name is "new anti-odor and anti-clogging floor drain". The high thing is, if the U-shaped tube is made of metal tube blanks, special equipment is required for bending. If the U-shaped tube is made of metal or non-metallic material, and the manufacturing process of mold molding is used, the mold investment is not only high, but the mold structure is also In addition, the sealing used in this technology is to achieve the purpose of sealing through the water retained in the U-shaped structure of the U-shaped pipe. However, in some special cases, a certain pressure will be generated in the pipe. When the pressure is greater than the water pressure retained by the U-shaped structure, it will reversely pass through the water-tight part in the form of airflow or air bubbles and enter the room.

For another example, the Chinese utility model patent application number is 200920000038.3, the authorized announcement number is CN201334708Y, and the technology disclosed by the name "floating floor drain" has certain advantages in terms of sealing effect, but since the sealing mechanism is arranged on the body Inside, resulting in a large structural size of the body, which is not conducive to the installation of the floor drain in a limited space

[0003] For another example, the Chinese utility model patent application number is 201820526510.6, the authorized announcement number is CN208152210U, and the technology disclosed by the name is "a floor drain". The main sealing principle adopted by this technology is to achieve The purpose of sealing, however, due to the inevitable errors in the manufacture and installation of the movable door and the lower outlet, effective sealing cannot be achieved, especially when there is garbage or other foreign objects at the joint of the movable door and the lower outlet. when the sealing effect is completely lost

The prior art listed above is a representative technology in the prior art. Due to the complexity of the prior art, the number of existing technologies cannot be listed one by one, but they more or less exist in the prior art listed above. partial or total defect
