Description

Technical Field

[0001] This utility model belongs to the field of floor drain technology and relates to an adaptive water seal anti-odor floor drain core. Background Technology

[0002] Floor drains are an important interface connecting the drainage pipe system to the indoor floor. As a crucial component of the drainage system in residences, they are also widely used in same-floor drainage systems. With people's increasing demands for quality of life, floor drains, as an essential part of the residential drainage system, not only fulfill their function of connecting to the sewer pipes, but also require increasingly higher standards for their functions in preventing odors, harmful gases, insects, and germs from entering.

[0003] Patent CN210369244U discloses a drain core for a floor drain, comprising a body and a core. The body includes an upper section and a lower section connected by threads. The lower part of the upper section is provided with an annular protrusion. A sealing element is provided between the upper section and the lower end. The sealing element includes a connecting section and a sealing section. The inner wall of the connecting section is provided with an annular groove, and the outer wall of the connecting section is provided with a ridge ring. The ridge ring presses against the connecting section, so that the inner wall of the connecting section abuts against the upper section, and the sealing element is not easily moved during use.

[0004] The above-mentioned drain core products have a certain sealing and odor-proof effect through the cooperation of the core and the sealing ring, but there are still some shortcomings: gaps may appear between the contact points of the sealing element and the core due to the deformation of the sealing element, which will affect the sealing effect and eventually reduce the odor-proof effect. Traditional water seals can no longer prevent odors after the water evaporates to a low level, and the water seal may be drawn away by the siphon effect of the drain pipe, causing it to fail. Summary of the Invention

[0005] This utility model addresses the aforementioned problems in existing technologies by providing an adaptive water seal odor-proof floor drain core. The technical problem this utility model aims to solve is that existing floor drain cores have insufficient odor-proof effect.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] An adaptive water-seal anti-odor floor drain core includes a mounting frame and a core. The mounting frame has a drain hole. The lower end of the core is rod-shaped and slidably connected to the mounting frame vertically. Both the core and the mounting frame are equipped with magnets to ensure that the core always tends to move upward. The core is characterized in that the upper end is an open, upward-facing bowl shape. The mounting frame has a downward-protruding, tubular drain tube. The drain hole is formed in the inner cavity of the drain tube. The lower end of the drain tube is located in the inner cavity of the upper end of the core. The upper end of the core forms a seal with the mounting frame along its opening in a circumferential direction.

[0008] By designing the upper end of the core to be an upward-opening bowl shape, and positioning the lower edge of the drain tube within the inner cavity of the upper end of the core, a seal is achieved by the upper edge of the core pressing against the lower end. When the upper end of the core is filled with water and at rest, the upper edge of the core is always higher than the lower end of the drain tube. During normal use, water first enters the upper end of the core, impacting it and causing it to move downwards to complete the drainage. After drainage, the core returns to its original position, still containing water. If the magnetic force of the magnet is strong enough, the core returns to its initial position, maintaining a mechanical seal, while the lower edge of the drain tube remains lower than the water level stored in the upper end of the core, forming a water seal. It can achieve double sealing for better sealing effect. When the magnetic force of the magnet is moderate, the core containing water will be lower than the initial position due to the gravity of the water. This ensures that the upper edge of the core is still higher than the lower edge of the drain tube. As a result, the lower edge of the drain tube is lower than the water level stored at the top of the core, forming a water seal. The water seal has a better sealing effect and is conducive to improving the sealing and odor prevention effect under normal conditions. As the water evaporates and dries up, the core can also adaptively move upward to raise the water level, maintaining the water seal effect until it comes into contact with the core again to form a mechanical seal, maintaining a good odor prevention effect.

[0009] In the aforementioned adaptive water-seal anti-odor drain core, when the core moves downwards to abut against the limiting position of the mounting bracket, the upper edge of the core is lower than the lower edge of the drain pipe. This allows the core to overcome magnetic force and move downwards under the impact of water flow, ensuring that the upper edge of the core is sufficiently far from the lower edge of the drain pipe, guaranteeing a large enough water passage space between them for smooth drainage. After drainage is complete, the core returns to its original position via magnetic force to form a water seal.

[0010] In the aforementioned adaptive water-sealed odor-proof drain core, the drain core also includes an annular sealing ring. This sealing ring is fixed to the mounting bracket and is arranged around the periphery of the drain cylinder. The upper edge of the core abuts against the sealing ring to form a seal. This ensures both a mechanical seal and prevents the sealing ring from being immersed in the water at the top of the core during water sealing, thus avoiding impurities in the water from adhering to the sealing ring as the water dries, thus guaranteeing a proper seal.

[0011] In the aforementioned adaptive water-seal anti-odor drain core, the sealing ring is integrally connected with a downward-folded lip. This allows for a greater deformation range during the contact between the lip and the core, facilitating the formation of a mechanical seal even after the core has shifted downwards a certain distance.

[0012] In the aforementioned adaptive water seal anti-odor floor drain core, the lower end of the drain cylinder is constricted. This allows for a larger flow area between the outer periphery of the lower end of the drain cylinder and the inner edge of the upper opening of the core, preventing water flow obstruction during drainage.

[0013] In the aforementioned adaptive water-seal anti-odor drain core, the upper end of the core is radially folded along the opening to form an annular flange. This flange, by abutting against the sealing ring, increases the sealing contact area, thereby enhancing and stabilizing the sealing effect.

[0014] Compared with the prior art, the advantages of this utility model are as follows:

[0015] This adaptive water seal odor-proof drain core can form a water seal effect for a certain period of time after each drain, improving the odor-proof effect. Even if it is not used for a long time, it can still achieve a mechanical seal to ensure a stable odor-proof effect. Attached Figure Description

[0025] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0026] like Figure 1-5As shown, this adaptive water seal anti-odor floor drain core includes a mounting frame 1 and an umbrella-shaped core 3. The basic structure of the mounting frame 1 can refer to existing technology. The mounting frame 1 has a drain hole 11 that runs vertically through the drain for water drainage. Specifically, the mounting frame 1 has a downward-protruding drain cylinder 12, and the inner cavity of the drain cylinder 12 forms the drain hole 11. Specifically, the mounting frame 1 includes a body and a drain cylinder 12. The drain cylinder 12 is inserted into the body. The lower end of the core 3 is rod-shaped and slides vertically onto the mounting frame 1. The core 3 faces upward and is directly opposite the drain cylinder 12. The core 3 and the mounting frame 1... Each component 1 is equipped with a magnet 4 to ensure that the core 3 is always subjected to an upward magnetic repulsion force. The position of the magnet 4 is in the prior art. The upper end of the core 3 is an open bowl shape with its opening facing upward. The upper end of the core 3 is folded outward radially along the opening to form an annular flared edge 31. The lower end of the drain tube 12 is constricted and located in the inner cavity of the upper end of the core 3. By reasonably designing the relationship between the magnitude of the magnetic repulsion force and the weight of the core 3 and the weight of the core 3 when it is filled with water, the upper edge of the core 3 is always higher than the lower end of the drain tube 12 when the upper end of the core 3 is filled with water and its position is stationary. The drain core also includes an annular sealing ring 2, which is fixed to the outer periphery of the drain tube 12. The sealing ring 5 is arranged around the outer periphery of the drain tube 12. The upper edge of the core 3 abuts against the sealing ring 5 to form a seal. The sealing ring 2 is integrally connected with a downward folded lip 21.
