Description

Technical Field

[0001] The utility model relates to an anti-odor core, a floor drain and a disassembly and assembly tool thereof. Background Art

[0002] As an important component connecting the indoor floor and the sewer pipe, the anti-odor floor drain is mainly used to drain the sewage on the indoor floor and prevent the odor in the sewer pipe from flowing back into the room. However, in actual use of the traditional anti-odor floor drain, as Figure 6 shown, on the one hand, due to the influence of the height of the indoor floor, the anti-odor floor drain cannot be completely placed in the sewer pipe after installation, and there will be a height difference between the anti-odor floor drain and the sewer pipe, which is likely to cause leakage hidden danger during drainage; on the other hand, due to installation deviation, the odor in the sewer pipe is likely to flow back between the anti-odor floor drain and the sewer pipe and then be released into the room, causing indoor odor and stench; therefore, the existing technology still needs to be improved and developed. Summary of the Invention

[0018] As Figure 1 、 Figure 2 shown, an anti-odor core of an embodiment of the present utility model includes an anti-odor inner core (1) and a sleeve (2). The outer wall of the anti-odor inner core (1) is positioned and sealed with the inner wall of the sleeve (2). The lower end of the sleeve (2) extends into the sewer pipe, enabling the anti-odor core to better adapt to the height deviation of the indoor floor during the actual construction process, so that the sewage flowing into the anti-odor core can completely flow into the sewer pipe, avoiding potential leakage hazards.

[0019] Further, as Figure 1 、 Figure 2As shown in the figure, the outer wall of the odor-proof inner core 1 in this embodiment is threadedly connected to the outer wall of the sleeve 2. A first limiting ring 1-1 is provided at the upper end of the odor-proof inner core 1, and first clamping grooves 1-2 are symmetrically arranged at the center of the upper wall surface. A first limiting groove 2-1 is provided on the inner wall of the sleeve 2. The first limiting ring 1-1 is used in cooperation with the first limiting groove 2-1, so as to relatively fix the relative position after the threaded connection of the odor-proof inner core 1 and the sleeve 2. The installation is convenient, and compared with the traditional connection of the odor-proof core, the connection accuracy is high and the air tightness is good. In addition, a first sealing ring 3 can be further arranged between the first limiting ring 1-1 and the first limiting groove 2-1 to further improve the air tightness of the connection between the odor-proof inner core 1 and the sleeve 2 and enhance the odor-proof effect.

[0020] Further, as Figure 1 , Figure 2 shown, the odor-proof inner core 1 in this embodiment includes a drain pipe 4 and a flap 5. The flap 5 is hinged to the drain pipe 4. A balance structure is provided on the flap 5. The balance structure is used to apply a turning torque to the flap 5. The turning torque can rely on gravity, magnetism or spring torque. In this embodiment, a counterweight 6 is arranged on one side of the flap 5. When not draining water, the flap 5 closes the water outlet of the drain pipe 4 under the action of the gravity of the counterweight 6. When draining water, the flap 5 opens the water outlet of the drain pipe 4 under the action of water. After the drainage is completed, the flap 5 closes the water outlet of the drain pipe 4 again under the action of the gravity of the counterweight 6. The structure is simple and convenient to use.

[0021] As Figure 3 , Figure 4 shown, the present utility model also provides a floor drain, which includes the above-mentioned odor-proof core, and also includes a mounting seat 7. A mounting hole 7-1 is provided at the center of the mounting seat 7. The inner wall of the mounting hole 7-1 is threadedly connected to the outer wall of the sleeve 2. A second limiting ring 2-2 is provided at the upper end of the sleeve 2, and second clamping grooves 2-3 are symmetrically arranged at the center of the upper end. A second limiting groove 7-11 is provided on the inner wall of the mounting hole 7-1. The second limiting ring 2-2 is used in cooperation with the second limiting groove 7-11, so as to relatively fix the relative position after the threaded connection of the sleeve 2 and the mounting seat 7. And compared with the clamping connection between the traditional floor drain and the mounting seat, the installation accuracy in this embodiment is higher and the air tightness is better. In addition, a second sealing ring 8 can be further arranged between the second limiting ring 2-2 and the second limiting groove 7-11 to improve the air tightness between the sleeve 2 and the mounting seat 7 and enhance the odor-proof effect.

[0022] As Figure 5As shown in the figure, the present utility model further provides a disassembly and assembly tool, which is used based on the above-mentioned floor drain. It includes a tool body 9, and the tool body 9 is divided into a first straight plate portion 9-1 and a second straight plate portion 9-2 in the shape of a straight plate. Among them, the length of the first straight plate portion 9-1 is greater than the inner diameter of the upper end of the odor-proof inner core 1 and less than the inner diameter of the first limiting groove 2-1. The width of the first straight plate portion 9-1 fits the first card slot 1-2, and the height of the first straight plate portion 9-1 is greater than the height difference between the upper wall surface of the odor-proof inner core 1 and the sleeve 2 after installation. The length of the second straight plate portion 9-2 is greater than the inner diameter of the upper end of the sleeve 2 and less than the inner diameter of the second limiting groove 7-11, and the width of the second straight plate portion 9-2 fits the second card slot 2-3. When in specific use, the connection between the sleeve 4 and the mounting hole 7-1 can be tightened or loosened with the second straight plate portion 9-2, or the connection between the odor-proof inner core 1 and the sleeve 2 can be tightened or loosened with the first straight plate portion 9-1. Its structure is simple and it is convenient to use.
