[0002] Floor drains are a crucial interface between a home's drainage system and the indoor floor. Their quality directly impacts the indoor environment and air quality. Traditional floor drains rely solely on water retention to form a water seal or sealing structure to isolate the living space from the plumbing system. If the water seal fails or the seal is not tightly closed, the sewer is completely disconnected from the indoor space, allowing odors and toxic and hazardous gases to escape through the pipes and into the home. Furthermore, the development of existing floor drain cores relies solely on structural innovation and design, failing to address the root causes of odor and bacterial growth. Utility Model Content

[0003] The purpose of the utility model is to provide an odor-proof floor drain core and a floor drain assembly in view of the deficiencies in the prior art, so as to solve the problem that the odor-proof and antibacterial effects of the floor drain core in the prior art are poor.

The indoor sewage can be discharged through the opening at the upper end of the guide cylinder, enter the water storage cup-shaped body 1, and then be discharged through the flow hole 3. Water is stored in the water storage cup-shaped body 1 to form a water seal. Since the flow hole 3 is above the anti-odor and antibacterial body 2, the water stored in the water storage cup-shaped body 1 will soak the anti-odor and antibacterial body 2 when the water seal is formed. At the same time, when draining water through the anti-odor floor drain core, the sewage will flush the anti-odor and antibacterial body 2 after entering the guide cylinder. In this process, the anti-odor and antibacterial body 2 can also play an anti-odor and antibacterial role on the discharged sewage. The anti-odor floor drain core can achieve active anti-odor and antibacterial effects by utilizing the setting of the anti-odor and antibacterial body 2, and solve the problems of the existing floor drain core that is easy to smell and breed bacteria from the source.

[0028] Furthermore, the detachable arrangement of the guide cylinder can facilitate taking out the guide cylinder for cleaning or replacing the deodorizing and antibacterial body 2 .

[0036] Specifically, the funnel portion 5, the first straight portion and the second straight cylindrical portion 7 are integrally formed to form a guide cylinder. The first straight cylindrical portion 6 can be directly connected to the lower end of the funnel portion 5. A placement groove that can carry and accommodate the deodorizing and antibacterial body 2 is formed between the first straight cylindrical portion 6 and the second straight cylindrical portion 7 by setting a diameter-changing step. The upper end of the placement groove is open, which facilitates operations such as placing and replacing the deodorizing and antibacterial body 2.

[0037] Optionally, the outer diameter and inner diameter of the deodorizing and antibacterial body 2 match the inner diameter of the first straight cylindrical portion 6 and the inner diameter of the second straight cylindrical portion 7 respectively.

[0038] Specifically, the outer diameter of the deodorizing and antibacterial body 2 can be slightly smaller than the inner diameter of the first straight cylindrical portion 6, which can facilitate the removal and placement of the deodorizing and antibacterial body 2 and form a certain limiting effect. The inner diameter of the deodorizing and antibacterial body 2 is preferably not smaller than the inner diameter of the second straight cylindrical portion 7 to avoid affecting the sewage flow.

[0039] Optionally, the deodorizing and antibacterial body 2 has an outer diameter of 1.0-20 cm, an inner diameter of 0.5-15.0 cm, and a thickness of 0.1-5.0 cm.

When the wastewater passes through the odor-proof floor drain core, it is converged through the funnel portion 5. During the process of the wastewater flowing downward from the funnel portion 5, the odor-proof and antibacterial body 2 is flushed, and the odor-proof and antibacterial body 2 is used to achieve the sterilization and disinfection effect on the wastewater; Figure 2As shown, wastewater passing through the second straight portion 7 flushes through the floor drain self-sealing cover 8, enters the water cup 1, and is discharged through the flow hole 3. After the wastewater is discharged, the water remaining in the water cup 1 forms a water seal. Because the flow hole is above the deodorizing and antibacterial body 2, the liquid level is higher than the deodorizing and antibacterial body 2, soaking the deodorizing and antibacterial body 2, continuously performing its deodorizing and sterilizing functions, effectively preventing odor backflow and achieving excellent deodorizing effects. The diversion cylinder and water cup 1 are detachable and can be directly removed for cleaning or replacement of the deodorizing and antibacterial body 2, making operation simple and convenient.
