Abstract
The invention relates to a floor drain and a manufacturing method thereof. The floor drain comprises a drain cover and a drain body; the drain body comprises a cylindrical pipe; the lower part of the cylindrical pipe is rotationally connected with a stop plate through a counterweight component; the stop plate is bent into a curved surface; the curvature radius of the curved surface is half of the outside diameter of the cylindrical pipe; and the cylindrical pipe is provided with an arc part hermetically matched with the stop plate. The stop plate on the lower part of the cylindrical pipe of the floor drain is bent into the curved surface with certain curvature radius, and the curvature radius is half of the outside diameter of the cylindrical pipe, so through the structure, when the floor drain drains water, the opening angle of the stop plate relative to the bottom of the cylindrical pipe can reach 90 degrees, the drainage area is large, and accumulated water return can be well avoided when a large amount of sewage needs to be drained.
Description
Technical field
The present invention relates to a kind of floor drain and preparation method thereof.
Background technology
Floor drain is as common decoration accessory, be installed in the ground surface of kitchen, washroom and balcony, connect sewerage system, as the vitals of drainage system in the dwelling house, the performance quality of floor drain directly affects the quality of room air, and is extremely important to the control of the peculiar smell between bathroom.
Present common floor drain, as shown in Figures 1 and 2 structure is arranged, comprise housing 1, housing 1 top is provided with drain cover 2, housing 1 inwall is provided with brace table 3, be provided with the tabular joint ring 4 that is tightly connected with inner walls between brace table 3 and the drain cover 2, the outer middle side part of joint ring 4 is provided with annular groove, is provided with sealing ring 7 in the annular groove.Joint ring 4 inboards are installed with the water inlet pipe 5 to downward-extension, and the lower end of water inlet pipe 5 is provided with can movable seal cover 6.Seal cover 6 comprises cover plate 61, and an end of cover plate 61 and water inlet pipe 5 lower ends closely cooperate, and cover plate 61 middle parts are provided with gripper shoe 63, and gripper shoe 63 is hinged by rotating shaft 8 and water inlet pipe side, and the other end of cover plate is provided with balance weight iron 62.Adopt the floor drain of this structure, when not having sewage to flow to floor drain, balance weight iron 62 is pressed to water inlet pipe 5 lower ends with cover plate 61, and makes foul smell, insect in its effective prevention sewer that closely cooperates enter indoor; Sewage in flowing to water inlet pipe 5 increases, and when the weight balancing of seal cover was broken, sewage just pressed off the cover plate 61 of water inlet pipe 5 lower ends, enters smoothly sewer, and sewage discharging is complete, and cover plate 61 recovers again sealing state under balance weight iron 62 effects.It is simple in structure, easy to use, can prevent effectively that foul smell, insect in the sewer from entering indoor, but, because the maximum open angle α of cover plate 61 relative water inlet pipes 5 lower ends is much smaller than 90 °, displacement will be greatly affected, having in the situation that large amount of sewage need to discharge, might cause and return the water phenomenon.
In addition, at present common drain structure also has structure as shown in Figure 3, includes Lou body and drain cover 2, and Cancellation Missed 2 is fixedly connected on Lou on the body by the magnetic coupling mode.Described leakage body top has mounting platform 45, be provided with a columniform magnet installing rack 48 in the cylindrical cavity 44 at leakage body center, the upper end of this magnet installing rack 48 is circumferentially stretched out connecting rod 41 and is linked to each other with the sidewall of cylindrical cavity 44, the bottom of cylindrical cavity 44 is uncovered, leak body also comprise one with the suitable circular bottom 43 in cylindrical cavity 44 bottoms, these circle bottom 43 centers are provided with a through hole, vertically an end of bar 42 is fixing by through hole and circular bottom 43, vertically the other end of bar 42 extend in the magnet installing rack 48, this vertical bar is mobilizable being located in the magnet installing rack 48 about in the of 42, this vertical bar 42 consists of spacing the cooperation with the lower end of magnet installing rack 48, vertically is provided with a magnet in the bar 42.The floor drain of this structure, when being full of water in the floor drain, bottom 43 separates with cylindrical cavity 44 bottoms under the pressure of water deadweight, and water is seeped into sewer pipe from separation.After water had oozed, magnet installing rack inner magnet attracted the magnet in the vertical bar 42, bottom 43 is drunk up cover cylindrical cavity 44 bottoms, prevented that the foul smell in the sewer from emerging.The floor drain of this spline structure is owing to the suction that relies on magnet is realized sealing, in case magnet lost efficacy, floor drain will not reach the purpose of deodorization, and magnet is also possible demagnetization under high-temperature condition, in case the magnet demagnetization will not reach the deodorization purpose.Further, owing to leak the body center vertical bar is set, displacement also can be influenced, having in the situation that large amount of sewage need to discharge, might cause and return the water phenomenon.
Summary of the invention
The objective of the invention is for existing floor drain displacement littlely, in the situation that large amount of sewage need to discharge, have ponding and return water problems, provide a kind of displacement large, can deodorization, anti-water, the anticlogging floor drain of returning.
To achieve these goals, a kind of floor drain of the present invention, comprise Cancellation Missed and leak body, described leakage body includes cylindrical tube, avris is rotationally connected a catch by a weight member under the described cylindrical tube, described catch bends to curved surface, and the radius of curvature of described curved surface is half of external diameter of described cylindrical tube, and described cylindrical tube has the curved portions that is sealed and matched with described catch.
Above-mentioned floor drain, wherein, the expansion shape of described catch is oval, and the minor axis length of the ellipse that is launched into equates with the external diameter of described cylindrical tube, long axis length equates with the arc length of described curved portions.
