Embodiment 1

[0034] Such as Figure 1 to Figure 3 As shown, a floor drain core provided in this embodiment includes an outer shell 1 and an inner core 2;

[0035] The shell 1 includes a shell body 11 and a flange 12;

[0036] The inner core 2 is arranged in the outer shell 1, and a first sealing member 3 is arranged between the inner core 2 and the outer shell 1;

[0037] The shell body 11 is provided with at least one drainage port 111, and the bottom of the shell body 11 and the inner core 2 form a water seal area 112;

[0038] A water flow channel 113 is formed between the inner core 2 and the outer shell 1 .

[0039] The floor drain core includes an outer shell 1 and an inner core 2, which are sealed with water as a whole without gaps, effectively preventing harmful substances such as gas, insects, viruses, bacteria, etc. 11 is provided with at least one drain port 111 to drain water at the same time, so that the flow velocity and flow rate of water are maximized, and impurities suc...

Embodiment 2

[0050] This embodiment also provides a floor drain, including the floor drain core provided in Embodiment 1 above, and also includes a floor drain installation plate 4;

[0051] A mounting part 51 is provided on the floor drain mounting plate 4;

[0052] The flange 12 is installed on the floor drain installation plate 4 through the installation portion 51 , and the second sealing member 5 is arranged between the housing 1 and the floor drain installation plate 4 .

[0053]The floor drain includes a floor drain core and a floor drain installation plate 4, and a second sealing member 5 is arranged between the floor drain core and the floor drain, eliminating the gap between the floor drain installation plate 4 and the shell 1, and limiting the path for water to enter the pipeline. It can enter from the inner core 2, and be discharged from the water reservoir through the water channel 113, while preventing gas, insects, viruses, bacteria and other harmful substances in the pipeli...

Abstract

An embodiment of the invention discloses a floor drain core and a floor drain, and relates to the technical field of sanitary and bathroom equipment. The floor drain comprises a casing and an inner core. The casing comprises a casing body and a flange, the inner core is disposed in the casing, and a first seal is arranged between the inner core and the casing. The casing body is provided with at least one drain port, a water seal zone is formed between the bottom of the casing body and the inner core, and a water flow passage is formed between the inner core and the casing. The first seal is added to restrict the path of water entering the pipeline and prevents gas, insect ants, viruses, bacteria and other harmful substances in the pipeline from entering a room through the gap between theinner core and the casing, so that the problem of bacterial growth caused by the gap between the casing and the inner core is solved.

Description

technical field [0001] The invention relates to the technical field of sanitary equipment, in particular to a floor drain core and a floor drain. Background technique [0002] The floor drain is an important interface connecting the drainage pipe system and the indoor floor. As an important part of the drainage system in the residence, its performance directly affects the quality of the indoor air, and is very important for the odor control in the bathroom. [0003] The water-sealed floor drain is one of the floor drains. It mainly includes an outer shell and an inner core. There is an opening for water to flow out at the bottom of the inner core. There is an opening for water to flow out on the outer shell. The water between the shell and the inner core is sealed to prevent the odor in the sewer from entering the room, but only the stagnant water is used for sealing, and the sealing effect is poor, and the odor and bacteria in the sewer can still pass along the shell. The ...
