Description
Technical Field
[0001] The utility model relates to a building hardware fitting, in particular to a semi-submersible anti-odor floor drain. Background Art
[0002] Floor drains and drain pipes play a crucial role in the drainage of domestic wastewater. Since domestic wastewater contains many harmful gases to the human body, the performance of floor drains or drain pipes directly affects the indoor air quality. In this process, the anti-odor core becomes an important part of floor drains and drain pipes, undertaking the important task of preventing the backflow of odors. However, the quality of anti-odor cores on the market is uneven, and the following problems generally exist.
[0003] 1. Limitations of water-sealed anti-odor cores: Existing anti-odor technologies mainly include water-sealed anti-odor cores and drainage anti-odor cores that rely on the magnetic principle to open and close. The water-sealed anti-odor core forms a water seal layer by retaining a certain amount of water in the floor drain to block the backflow of odors. In daily use, this method can effectively prevent odors from entering the room. However, the water-sealed anti-odor core has obvious limitations:
[0004] 2. Drying up of the water seal: When the floor drain is not used for a long time, the retained water will gradually evaporate. After the water seal layer dries up, it loses its airtight effect, and odors will enter the room through the floor drain, affecting the air quality.
[0005] 3. Short water seal time limit: Due to the design of the floor drain and the volume limitation of the water seal layer, the time that the water seal layer can maintain is short, especially in dry seasons or climatic conditions, the evaporation speed is faster.
[0006] To solve the deficiencies of the water-sealed anti-odor core, drainage anti-odor cores that rely on the magnetic principle to open and close have also emerged on the market. This type of anti-odor core controls the opening and closing of the floor drain through magnetism and automatically closes when there is no wastewater flowing in to prevent the backflow of odors. However, this design also has its limitations:
[0007] 1. Complex structure: The internal structure of the magnetic anti-odor core is relatively complex, involving magnetic materials and precise opening and closing mechanisms, which increases the manufacturing difficulty.
[0008] 2. High cost: Due to the complexity of materials and manufacturing processes, the cost of the magnetic anti-odor core is relatively high, which is not conducive to large-scale promotion and popularization.
[0009] In addition, in the existing floor drain designs, most of the connected drain pipes are pipes with a diameter of 50 millimeters. This design requires the drain outlet of the floor drain to be inserted into a pipe with a smaller diameter, resulting in a limited volume of the water seal structure of the floor drain. This limitation brings several problems:
[0010] 1. Small water seal volume: Due to the small pipe diameter, the volume of the water seal structure inside the floor drain is limited, and it is difficult to retain enough water to form an effective water seal layer.
[0011] 2. Poor drainage: Small diameter pipes are prone to poor drainage, especially when a large amount of wastewater is discharged, which can easily cause blockage and affect normal use.
[0012] 3. Easy to clog: Debris in wastewater easily accumulates in small-diameter pipes, causing pipe clogging and increasing the difficulty of cleaning and maintenance. Therefore, it is necessary to make further improvements. Utility Model Content

[0015] The water inlet is provided with a water guiding slope, which is arranged to be inclined downward and extends to the downward orthographic projection range of the water inlet;
[0016] The water storage pipe is also provided with an isolation plate, the top of which is connected to the water guide slope, and the bottom of which extends into the water storage area and is arranged close to the bottom of the water storage area, so that a sewage channel is formed between the bottom of the isolation plate and the bottom of the water storage area;
[0017] Furthermore: the height of the drain outlet is higher than the lowest point of the isolation plate, and a valve is hingedly installed on the side wall of the isolation plate. The valve movably covers the sewage channel to seal it, and the valve swings toward the drain outlet to open the sewage channel for drainage.
[0018] Furthermore: the valve is arranged to be inclined at 30° to 50° relative to the vertical line.
[0019] Furthermore, the isolation plate isolates the water storage area into a water inlet area and a water outlet area which are connected at the bottom, and the two are distributed in an inverted "C" shape.
[0020] Furthermore, the distance H between the highest point of the drain outlet 52 and the highest point of the panel 1 is 15 mm to 25 mm.
[0021] Furthermore, the distance K between the highest point of the drain outlet 52 and the lowest point of the water storage area is 25 mm-35 mm.
[0022] Furthermore, the distance Y between the lowest point of the partition plate 54 and the lowest point of the water storage area is 15 mm - 20 mm.
[0023] Furthermore, a water guide pipe 8 is sleeved outside the water storage pipe 5. The water guide pipe 8 is integrally wrapped outside the water storage pipe 5.

[0026] 3. The water storage area formed inside the water storage pipe can maintain sufficient water volume. Even when not in use for a long time, the water seal can be ensured to continue to exist, preventing the water seal from drying out and failing.
[0027] 4. With the optimized water storage pipe design, the water storage pipe in the present invention is reasonably designed. Its side wall is provided with a drain port to ensure that the waste water can be discharged smoothly. The capacity of the water storage area is designed sufficiently, avoiding the problem of limited water seal volume, thereby ensuring smooth drainage.
[0028] 5. The sleeved water guide pipe is not directly connected to the sewer pipe, so that the size of the water storage pipe structure is no longer limited by the size of the sewer pipe. In addition, the eccentric design of the water guide pipe and the sewage pipe forms the effect of a crankshaft variable diameter. When the position of the sewer pipe remains fixed during installation, rotating this floor drain can adjust the ground position of the floor drain port within a certain range, thus facilitating the installation and adjustment by users and reducing the dimensional accuracy requirements for the pre-buried sewer pipe.

[0033] The water inlet 51 is provided with a water guiding slope 53, which is arranged to be inclined downward and extends to the downward orthographic projection range of the water inlet 51;
[0034] The water storage pipe 5 is further provided with an isolation plate 54, the top of which is connected to the water guide slope 53, and the bottom of which extends into the water storage area and is arranged close to the bottom of the water storage area, and a sewage channel 55 is formed between the bottom of the isolation plate 54 and the bottom of the water storage area;
[0035] The height of the drain outlet 52 is higher than the lowest point of the isolation plate 54. A valve 6 is hingedly installed on the side wall of the isolation plate 54. The valve 6 movably covers the drain channel 55 to seal it. The valve 6 swings toward the drain outlet 52 to open the drain channel 55 for drainage.
[0036] In one of the domestic embodiments, the valve 6 is arranged to be inclined at 30° to 50° relative to the vertical line.
[0037] In one of the domestic embodiments, the isolation plate 54 isolates the water storage area into a water inlet area 56 and a water outlet area 57 with the bottoms connected, and the two are arranged in an inverted "C" shape.
[0038] In one of the domestic embodiments, the distance H between the highest point of the drain outlet 52 and the highest point of the panel 1 is 15 mm-25 mm.
[0039] In one of the domestic embodiments, the distance K between the highest point of the drain outlet 52 and the lowest point of the water storage area is 25 mm-35 mm.
[0040] In one of the domestic embodiments, the distance Y between the lowest point of the isolation plate 54 and the lowest point of the water storage area is 15 mm-20 mm.
[0041] In one of the domestic embodiments, the water storage pipe 5 is sheathed with a water pipe 8, which is entirely wrapped around the water storage pipe 5. A sewage pipe 81 extends downward from the bottom of the water pipe 8, and the center of the sewage pipe 81 is eccentrically arranged with respect to the center of the drainage hole 2.
[0042] Working principle: The semi-submersible deodorizing floor drain of the present invention provides excellent deodorizing effect and drainage performance through its unique design and structure. Its working principle can be explained in detail from the following aspects:
[0043] The basic structure of the floor drain: The floor drain includes a panel 1, a drainage hole 2 is formed in the hollow part of the panel, and a filter 3 is detachably installed on the drainage hole. A connection seat 4 extends downward from the bottom of the panel. The panel and the filter are made of stainless steel pipe or copper material as a whole, which keeps its appearance neat and beautiful while avoiding rust and corrosion during use.
[0044] A water storage pipe 5 is mounted on the connection seat. The water storage pipe 5 is made of corrosion-resistant plastic material. The water storage pipe is hollow to form a water storage area. The top of the water storage pipe is provided with a water inlet 51 connected to the drain hole, and the side wall of the water storage pipe is provided with a drain port 52 connected to the sewer.
[0045] 2. Water inlet and water storage: When wastewater enters the floor drain through the drain hole 2, the water flows through the filter screen 3 and enters the water storage pipe 5. The water guide slope 53 on the water inlet 51 guides the water flow into the water storage pipe. The water guide slope 53 is set to be inclined downward and extends to the downward projection range of the water inlet, ensuring that the water flows smoothly into the water storage area, reducing the impact of the water flow, and preventing splashing and noise.
[0046] 3. Function of the water storage area: The water storage area formed by the hollow inside of the water storage pipe 5 acts as a water seal in the floor drain. The isolation plate 54 divides the water storage area into an inlet area 56 and an outlet area 57, which are arranged in an inverted "C" shape. The top of the isolation plate is connected to the water guide slope 53, and its bottom extends into the water storage area and is arranged close to the bottom of the water storage area, forming a sewage channel 55 between the bottom of the isolation plate and the bottom of the water storage area. The sewage channel 55 is formed between the bottom of the isolation plate and the bottom of the water storage area, providing a channel for discharging sewage at the bottom of the water storage area. The height of the drain port 52 is higher than the lowest point of the isolation plate 54, ensuring that there is always a certain amount of water seal in the water storage area, submerging the sewage channel as a whole, and preventing the sewer pipe from returning to stink.
[0047] 5. Function of the valve: A valve 6 is hingedly installed on the side wall of the isolation plate 54. Under the action of gravity, the valve 6 movably covers the sewage channel 55 to seal it. The valve 6 swings toward the drain port 52 to open the sewage channel for drainage. When the water level in the water storage pipe rises to a certain height and can be discharged through the drain port, the valve 6 will be pushed open by the water flow to allow the wastewater to be discharged smoothly. When there is no wastewater flowing in, the valve will automatically close under its own weight to prevent odor from flowing back or other objects from entering in the opposite direction through the sewer pipe.
[0048] 6. Odor prevention function of the water seal: The water in the water storage area forms a water seal, effectively isolating the odor from the sewer. When there is no wastewater flowing in, the isolation plate and the valve work together to further enhance the odor prevention effect. Even when the floor drain is not used for a long time and the stored water dries up, the physical seal of the valve continuously plays the role of odor prevention.
[0049] 7. Cooperation between the water guide pipe and the sewage pipe: In addition, the present invention also designs a water guide pipe 8, which is integrally coated outside the water storage pipe 5. At the bottom of the water guide pipe, a sewage pipe 81 extends downward. The center of the sewage pipe is eccentrically arranged with the center of the drain hole. When the sewage is discharged from the drain outlet, it enters the water guide pipe 8 and is discharged into the sewer through the connection between the sewage pipe 81 and the sewer pipe.
[0050] It should be emphasized that: in this case, the drain outlet on the water storage pipe is not directly connected to the sewer. Therefore, the volume and internal structure of the water storage pipe are no longer limited by the diameter of the existing sewer pipe. Therefore, the flow area inside the water storage pipe and the volume of the water storage area can be designed to be larger, so that more water can be stored for sealing, and the larger amount of water effectively extends the sealing time. In addition, the larger flow area makes the drainage of this floor drain smoother and more stable, and it is not easy to be blocked.
[0051] Furthermore: The eccentric design of the water guide pipe and the sewage pipe forms the effect of a crankshaft variable diameter. When the position of the sewer pipe remains fixed during installation, rotating this floor drain can adjust the ground position of the floor drain opening within a certain range, which is convenient for users to install and adjust, and reduces the dimensional accuracy requirements for the pre-buried sewer pipe, making the installation of this floor drain more convenient and fast. Therefore, it can be widely promoted and used.
[0052] Obviously, the above embodiments are merely examples for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. The obvious changes or modifications derived therefrom are still within the protection scope of the claims of the present invention.
