Problems solved by technology

If the grate and protective part on the upper part of the traditional floor drain are removed, larger debris will enter the pipe and accumulate, which will cause blockage of the internal pipe of the drainage system
Due to the complex structure of the traditional floor drain, it is difficult to avoid the occurrence of the above-mentioned clogging situation. At the same time, the sewer will also smell bad, causing inconvenience to users, increasing the workload and difficulty of maintenance, and losing the proper function of the floor drain.

Embodiment 1

[0046] In Embodiment 1, the filter bucket 3 has a plurality of square through holes 31 on the side wall and the bottom surface, and an outwardly extending ring 32 is provided on the upper edge, and the ring 32 is placed on the second support platform 18 . The bottom of the filter barrel 3 is provided with a first trumpet-shaped bottom surface 35 , and a plurality of through holes 31 are opened on the first trumpet-shaped bottom surface 35 . The top center of the first trumpet-shaped bottom surface 35 is provided with a first column 33, the axis of the first column 33 is provided with a positioning counterbore 34, the opening of the positioning counterbore 34 is downward, and the opening is located on the first trumpet-shaped bottom surface.

[0047] The first trumpet-shaped bottom surface 35 of the filter barrel 3 or the first trumpet-shaped top surface 44 of the floating body 4 is provided with a protrusion, which serves to separate the filter barrel 3 and the floating body 4 ...

Embodiment 2

[0049] In the second embodiment, the filter barrel 3 only has elongated through-holes 31 on the side wall, and there is no through-hole 31 on the first trumpet-shaped bottom surface.

[0050] like Figure 14 Shown is the front view of the floating body 4 in the present invention; as Figure 15 Shown is a top view of the floating body 4 in the present invention.

[0051] The floating body 4 is an airtight hollow structure, the outer diameter of the floating body 4 is smaller than the inner diameter of the main body 1, a positioning bar 41 is arranged on the outer wall, and a support block 43 is arranged at the bottom. When water comes, the water flows from the floating body 4 and the main body. The gap between 1 flows down, and flows through the arc groove 15, and floats up the floating body 4, prevents the floating body 4 from being pressed by the weight of the water, increases the displacement, and ensures smooth drainage.

[0052] The top of the floating body 4 is provided...

Abstract

The invention discloses an automatic closing floor drain with an independent filtering barrel and an independent floating body. The automatic closing floor drain comprises a main body, the filtering barrel and the floating body; a water inlet is formed in the top of the main body, a water outlet is formed in the bottom of the main body, and a water outlet channel is formed between the water inletand the water outlet; the filtering barrel and the floating body are arranged in the water outlet channel, and the floating body is located on the lower portion of the filtering barrel; a flow guidingopening is formed in the upper portion of the water outlet, the flow guide opening is in a horn shape, and the edge with the larger opening is connected to the upper portion of the water outlet; an arc-shaped groove is formed in the lower portion of the inner wall of the main body, and the arc-shaped groove is connected with the lower portion of the flow guide opening; a through hole is formed inthe side wall of the filtering barrel; the bottom of the floating body is provided with a second horn-shaped bottom surface, and the second horn-shaped bottom surface is matched with the flow guide opening in shape; an arc-shaped outer wall is arranged at the joint of the second horn-shaped bottom surface and the side wall of the floating body. According to the floor drain, harmful gas in a sewerpipeline can be prevented from flowing out, the phenomenon of odor backflow of the sewer pipeline is avoided, and the accumulation of solid matter can be avoided.

Description

technical field [0001] The invention relates to a floor drain, in particular to an automatic closing floor drain with an independent filter barrel and an independent floating body. Background technique [0002] The floor drain is an important interface connecting the drainage system and the indoor ground. As an important part of the drainage system in the house, its performance directly affects the quality of the indoor air. Odor control is very important. The function and role of the floor drain is to eliminate the ground water and prevent the harmful gas generated by the drainage system from entering the indoor ground debris into the drainage system. The quality of the floor drain is mainly measured from four angles: drainage speed, deodorant effect, and easy maintenance. , Durability. [0003] During the drainage process of the floor drain, solids, fibers, hair, etc. tend to enter the drainage system together with the sewage. At present, the traditional (commonly used)...
