Abstract
Description
Technical Field
[0001] The present application relates to the technical field of drainage equipment, and in particular to a water replenishment floor drain structure. Background Art
[0002] The floor drain is an important component in the indoor drainage system. Conventional floor drains have two main functions: one is to drain the sewage on the ground, and the other is to prevent the return of odor from the sewer pipe. The most common solution for existing floor drains to prevent the return of odor from the sewer pipe is to set a water seal inside the floor drain. However, in some places with high requirements for environmental hygiene, such as hospitals, according to the "Technical Guidelines for Emergency Reconstruction of Severely Infectious Disease Areas (Rooms) in Hospitals (Trial)", floor drains should use water-sealed floor drains with filters and water traps. The water seal of the water trap is 50mm~75mm. In order to meet environmental hygiene requirements, the floor drains used in the above-mentioned places need to use water traps instead of water seals to prevent odor. However, when the floor drain is not used for a long time, the water inside the water trap will evaporate, causing the odor of the sewage system to enter the room through the floor drain and pollute the environment. Utility Model Content
[0003] In order to solve the problem in the prior art that water in the water trap of an existing floor drain will evaporate when not used for a long time, causing the floor drain to have a bad smell, the present application provides a water replenishing floor drain structure.
[0004] A water replenishment floor drain structure provided in the present application adopts the following technical solution: a water replenishment floor drain structure, comprising a connected floor drain assembly and a drain pipe, a water trap is arranged in the middle of the drain pipe, one side of the drain pipe is connected with a water replenishment pipe, the floor drain assembly comprises a floor drain body, the bottom surface of the floor drain body is arranged with a connecting portion for connecting the drain pipe, a valve core is arranged inside the floor drain body, the valve core comprises a valve core body, a diaphragm extends in all directions from the upper side of the valve core body, the edge of the diaphragm is attached to the inner wall surface of the floor drain body, a connecting rod is connected below the valve core body, the connecting rod extends downward to the inside of the water trap, and a floating block is detachably connected to the lower end of the connecting rod.
[0005] By adopting the above technical scheme, the water supply pipe is connected to the drain outlet of the wash basin or other water-using equipment. When other equipment drains water, part of the water flows into the water trap through the water supply pipe to replenish the water trap. When there is water inside the water trap, the float lifts the valve core upward through the connecting rod under the action of buoyancy, and the bottom surface of the valve core body is separated from the connection between the connecting part and the floor drain body. When draining water, the water flow impacts the edge of the diaphragm to separate the diaphragm from the inner wall of the floor drain body, and the water flows downward between the diaphragm and the inner wall of the floor drain body, and then flows into the water trap in the drain pipe through the connecting part. When there is no water inside the water trap, the float is no longer affected by buoyancy, and the bottom surface of the valve core body blocks the connection between the connecting part and the floor drain body. At the same time, the edge of the diaphragm is attached to the inner wall of the floor drain body, thereby realizing the sealing of the floor drain, preventing the odor inside the drain pipe from entering the room through the floor drain, and realizing the closure of the floor drain when the floor drain is not used for a long time.

[0008] Optionally, a diverter block is provided inside the connection between the water supply pipe and the drainage pipe.
[0009] By adopting the above technical solution, the diverter block divides the water in the water supply pipe, one part of which enters the drain pipe for drainage, and the other part enters the water trap to replenish the water trap.
[0010] Optionally, the bottom edge of the valve core body is set to an arc shape, a chamfer is set at the connection between the connecting part and the floor drain body, the diameter of the valve core body is larger than the inner diameter of the connecting part, the diameter of the valve core body is smaller than the inner diameter of the floor drain body, and a cavity is formed between the valve core body and the inner wall of the floor drain body.
[0011] By adopting the above technical solution, when the valve core body is not affected by buoyancy, the valve core body falls inside the floor drain body, the bottom surface of the valve core body contacts the connection between the connecting part and the floor drain body, and the valve core body closes the connection between the connecting part and the floor drain body to achieve the closure of the floor drain.
[0012] Optionally, a plurality of stoppers are evenly spaced along the circumferential direction on the inner wall of the floor drain body.
[0013] By adopting the above technical solution, when the valve core body moves upward due to the buoyancy, the block blocks the edge of the diaphragm, so that the place where the diaphragm edge contacts the block is recessed inward, thereby forming a through hole between the diaphragm edge and the inner wall of the floor drain body to facilitate the discharge of water. At the same time, the abutment between the diaphragm edge and the block can also provide an intuitive reference for adjusting the position of the valve core.
[0014] Optionally, the upper surface of the valve core is configured as a curved surface.
[0015] By adopting the above technical solution, the upper surface of the valve core is set to a spherical surface to guide water and facilitate drainage.
[0016] Optionally, a raised portion is provided in the middle of the upper surface of the valve core.

[0018] Optionally, a connecting hole is provided through the middle of the valve core, and the connecting rod is threadedly connected to the connecting hole.
[0019] By adopting the above technical solution, the connecting rod and the valve core are threadedly connected, which makes it easy to adjust the length of the connecting rod extending downward and thus adjust the position of the float to adapt to floor drains and drain pipes of different sizes.
[0020] Optionally, a support frame for limiting the connecting rod is provided inside the connecting part, the connecting rod is movably inserted in the middle of the support frame, the surface of the support frame is hollowed out, the support frame is movably provided inside the connecting part, and a limiting protrusion for supporting the support frame is provided on the side wall of the connecting part.
[0021] By adopting the above technical solution, the support frame is used to limit the connecting rod radially to prevent the connecting rod from deviating.
[0022] Optionally, the floating block is sleeved on the outside of the connecting rod, and the floating block and the connecting rod are connected by interference fit.
[0023] By adopting the above technical solution, the floating block movable sleeve is arranged on the outside of the connecting rod for easy disassembly and assembly.

[0035] The following is combined with Figure 1-5 This application is described in further detail.
[0036] This embodiment discloses a water replenishment floor drain structure.
[0037] Reference Figure 1 A water replenishment floor drain structure includes a drain pipe 2, a water trap 3 is arranged at one end of the drain pipe 2, a floor drain assembly 1 is connected above the water trap 3, a water replenishment pipe 4 is connected to the side of the drain pipe 2 connected to the end of the water trap 3 away from the floor drain assembly 1, and the water replenishment pipe 4 is connected to the drain outlet of water-using equipment such as a washbasin.
[0038] Reference Figure 1 and Figure 2The floor drain assembly 1 includes a floor drain body 11, a connecting portion 111 is arranged in the middle of the bottom surface of the floor drain body 11, the floor drain body 11 is connected to the drain pipe 2 through the connecting portion 111, a valve core 13 is arranged in the middle of the floor drain body 11, the valve core 13 includes a valve core body 131, the bottom edge of the valve core body 131 is arranged in an arc shape, a chamfer is arranged at the connection between the connecting portion 111 and the floor drain body 11, the diameter of the valve core body 131 is larger than the inner diameter of the connecting portion 111, so that the valve core body 131 can block the inside of the connecting portion 111, the diameter of the valve core body 131 is smaller than the inner diameter of the floor drain body 11, a cavity is formed between the valve core body 131 and the inner wall of the floor drain body 11, the upper part of the valve core body 131 is arranged as a curved surface and a raised portion 133 is arranged in the middle, and the raised portion 133 is arranged to facilitate taking the valve core 13, and a diaphragm 132 is extended to the surrounding area from the upper edge of the valve core body 131, and the diaphragm 132 is made of a flexible material, and the diaphragm 132 is arranged along the The thickness gradually decreases from the radial direction to the edge, and the edge of the diaphragm 132 is attached to the inner wall of the floor drain body 11. A connecting rod 15 is connected to the middle of the bottom surface of the valve core body 131. A connecting hole is penetrated through the valve core body 131, and the connecting rod 15 is threadedly connected to the connecting hole. The connecting rod 15 extends downward to the inside of the water trap 3, and a floating block 16 is connected to the end of the connecting rod 15. When the water level inside the water trap 3 is at the lowest water seal level, the floating block 16 lifts the valve core 13 upward through the connecting rod 15 under the action of buoyancy, and the bottom surface of the valve core body 131 is separated from the connection between the connecting part 111 and the floor drain body 11. The water entering the floor drain body 11 can be transported to the drain pipe 2 through the connecting part 111. When the water level inside the water trap 3 is lower than the lowest water seal level, the valve core 13 falls under the force of gravity, and the valve core body 131 closes the connection between the connecting part 111 and the floor drain body 11, thereby closing the floor drain assembly 1 to avoid odor.
[0039] Reference Figure 3 The inner wall of the floor drain body 11 is evenly spaced with blocks 113 along the circumferential direction. When the valve core 13 moves upward under the action of buoyancy, the blocks 113 block and limit the diaphragm 132, so that the contact point between the edge of the diaphragm 132 and the block 113 is recessed inward, thereby forming a through hole between the edge of the diaphragm 132 and the inner wall of the floor drain body 11 to facilitate water discharge. At the same time, when the water flow is large, the water flow impacts the edge of the diaphragm 132, and the diaphragm 132 bends downward under the impact of the water flow, so that the gap between the diaphragm 132 and the inner wall of the floor drain body 11 becomes larger, which is more conducive to water discharge.
[0040] Reference Figure 4A support frame 14 for limiting the connecting rod 15 is arranged inside the connecting part 111, and the connecting rod 15 is movably inserted in the middle of the support frame 14. The surface of the support frame 14 is hollowed out to facilitate drainage. The support frame 14 is movably arranged inside the connecting part 111, and a limiting protrusion 112 for supporting the support frame 14 is arranged on the side wall of the connecting part 111. When disassembling the floor drain assembly 1, the support frame 14 can be directly taken out from the connecting part 111, so that the valve core 13, the connecting rod 15 and the floating block 16 are taken out of the floor drain body 11 by the edge.
[0041] Reference Figure 5 A diverter block 41 is arranged inside the connection between the water supply pipe 4 and the drainage pipe 2. The diameter of the diverter block 41 gradually increases along the water flow direction of the water supply pipe 4 to form a structure with a conical cross-section. When the water flows through the diverter block 41, the diverter block 41 diverts the water in the water supply pipe 4 to both sides. One part enters the drainage pipe 2 for drainage, and the other part enters the water trap 3 to replenish the water in the water trap 3.
[0042] The operating principle of a water replenishment floor drain structure is:
[0043] When installing the floor drain, insert the connecting rod 15 and the floating block 16 into the water trap 3 to ensure that the water trap 3 has water that reaches the highest water seal level, thread the valve core body 131 and the connecting rod 15, rotate the valve core body 131 to adjust the position of the valve core body 131 on the connecting rod 15, so that the diaphragm 132 at the edge of the valve core body 131 abuts against the stopper 113 on the inner wall of the floor drain body 11 under the action of the buoyancy of the floating block 16, and judge the position of the valve core body 131 according to the abutment between the edge of the diaphragm 132 and the stopper 113. The place where the valve core 13 is recessed inwardly to form a through hole, at this time, the valve core 13 is at the highest position inside the floor drain body 11, the bottom surface of the valve core body 131 is separated from the connecting portion 111, and a gap for water flow to pass through is formed between the bottom surface of the valve core body 131 and the connecting portion 111. At the same time, when the water level inside the water trap 3 is at the lowest water seal water level, the valve core body 131 is still lifted upward under the action of buoyancy. At this time, a gap for water flow to pass through is still formed between the bottom surface of the valve core body 131 and the connecting portion 111. When in use, if the water flow is small, water passes through the passage between the diaphragm 132 and the stopper 113. The water flows into the cavity between the floor drain body 11 and the valve core body 131 through the hole, and then enters the drain pipe 2 through the gap between the bottom surface of the valve core body 131 and the connecting portion 111 to be discharged. If the water flow is large, the water flow impacts the edge of the diaphragm 132 so that the edge of the diaphragm 132 is separated from the edge of the floor drain body 11, and the water enters the cavity between the floor drain body 11 and the valve core body 131, and then enters the drain pipe 2 through the gap between the bottom surface of the valve core body 131 and the connecting portion 111 to be discharged. When the floor drain assembly 1 and the water supply pipe 4 are not used for a long time, the water level inside the water trap 3 drops to the minimum water level. Below the water sealing level, the valve core 13 falls under the force of gravity, and the valve core body 131 closes the connection between the connecting part 111 and the floor drain body 11, thereby closing the floor drain assembly 1 to avoid odor. When water is used again, the water supply pipe 4 transports part of the water to the water trap 3 through the diverter block 41. When the water level in the water trap 3 is higher than the lowest water sealing level, the valve core 13 is lifted upward by buoyancy, and the bottom surface of the valve core body 131 is separated from the connecting part 111. A drainage gap is formed between the bottom surface of the valve core body 131 and the connecting part 111, so that the floor drain assembly 1 can drain water normally.
[0044] In summary, in this application, a valve core is arranged inside the floor drain, and the bottom of the valve core is connected to a float block through a connecting rod. When there is water in the water trap, the valve core is lifted upward by a ball so that the floor drain can drain normally. When there is no water in the water trap, the valve core closes the floor drain, avoiding the odor of the floor drain and improving the anti-odor effect of the floor drain. The structure is simple and easy to use. In this application, a water supply pipe is arranged on one side of the drain pipe, and the water supply pipe is connected to the end of the water trap away from the floor drain. The water supply pipe is arranged to realize automatic water supply to the water trap, reduce the labor intensity of maintenance personnel, and improve the anti-odor effect of the floor drain. Therefore, this application effectively overcomes various shortcomings in the prior art and has a high industrial utilization value.
[0045] The above embodiments are merely illustrative of the principles and effects of the present application and are not intended to limit the present application. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present application. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed in the present application shall still be included in the protection scope of the present application.
