[0002] The floor drain is an important interface connecting the sewer system and the indoor floor, and is widely used in kitchens, restrooms, toilets and other places. At present, the floor drains on the market include deep water seal type, T-type and flap drainage core, etc. These need to be placed in the pipe part, thus occupying the pipe space and cannot fill the entire pipe, resulting in a small water flow area and small flow, which cannot meet the large flow drainage needs. The drainage speed of the floor drain cannot keep up, and it is easy to fail to drain water in time and cause overflow. In addition, the entanglement and knotting of hair during the drainage process will affect the drainage and sealing effect of the floor drain, which is difficult to meet the needs of actual use and needs further improvement. Summary of the invention

[0003] The technical problem to be solved by the present invention is to overcome the deficiencies in the prior art and provide an ultra-large flow floor drain structure, which adopts a full-diameter pipe water flow method to form siphon drainage, thereby achieving ultra-large flow drainage of the floor drain.

[0004] The present invention is achieved through the following technical solutions:

[0005] A super-large flow floor drain structure, characterized in that it includes a floor drain embedded box, a hair cleaning piece, a floor drain core and a floor drain quick-release cover, wherein the floor drain embedded box, the hair cleaning piece and the floor drain quick-release cover are all provided with through holes in the middle, the hair cleaning piece is arranged below the floor drain core, the inner side surface of the hair cleaning piece is provided with a guide curved surface, the vertical section of the guide curved surface includes a fastest curve, the hair cleaning piece is connected to the floor drain core through a return piece, the floor drain core is sealed and connected to the floor drain quick-release cover through the action of the return piece, a plurality of guide columns are fixedly connected to the inner surface of the floor drain embedded box, each of the guide columns is arranged around the through hole of the floor drain embedded box, a plurality of guide column holes are provided on the surface of the hair cleaning piece relative to each guide column, the guide column passes through the guide column hole, the hair cleaning piece is clamped to the floor drain embedded box through a clamping piece, and the floor drain quick-release cover is detachably connected to the floor drain embedded box.

[0006] According to the above technical solution, preferably, a protrusion is fixedly connected below the through hole of the floor drain quick-release cover, and the protrusion is arranged around the inner diameter of the through hole of the floor drain quick-release cover. The floor drain core is provided with a sealing rubber ring along the circumferential direction, and the sealing rubber ring is relatively arranged below the protrusion.

[0007] According to the above technical solution, preferably, a connecting sleeve is provided in the middle of the hair cleaning piece, a positioning sleeve is provided in the middle of the lower surface of the floor drain core to be sleeved with the connecting sleeve, a positioning rod is fixed in the positioning sleeve, and the lower end of the positioning rod passes through the connecting sleeve.

[0008] According to the above technical solution, preferably, the return member is a spring, the spring is sleeved outside the positioning rod, and the two ends of the spring are respectively connected to the floor drain core and the hair cleaning member.

[0009] According to the above technical solution, preferably, the clamping part includes a limiting slot and a protruding slot, the middle part of the through hole of the floor drain embedded box is fixedly connected to the limiting slot through a connecting plate, and a protruding slot is provided below the hair cleaning part, and the protruding slot is clamped in the limiting slot.

[0010] According to the above technical solution, preferably, a floor drain cover is provided on the upper surface of the floor drain embedded box.

[0011] The beneficial effects of the present invention are:

[0012] 1. When the floor drain is draining, a gap is formed between the floor drain core and the floor drain quick-release cover, in which the first water-passing circular ring cross-sectional area, the second water-passing circular ring cross-sectional area, and the third water-passing circular ring cross-sectional area in the normal direction of the water flow in the cavity are approximately equal to the horizontal cross-sectional area of ​​the drainage pipe. The water-passing area does not change much when the floor drain is draining, and there is no local pressure loss along the way. The pipe can be fully drained to form siphon drainage, which can effectively meet the drainage needs of large flow rates;

[0013] 2. The inner side of the hair cleaning piece is provided with a guide surface whose vertical section is the fastest curve. The guide surface is used to guide the water flow, thereby reducing the energy loss of the water flow impact and making the water flow velocity larger;

[0014] 3. The hair cleaning part is arranged under the floor drain core to prevent the hair from getting tangled and affecting the sealing effect of the floor drain core. When the water flow from the floor drain flows back, the lifting force of the water flow on the bottom of the floor drain core and the elastic force of the return part form a line seal between the floor drain core and the quick-release cover of the floor drain, which prevents overflow, odor and insects.

[0015] 4. After the hair cleaning piece is snap-fitted and installed with the embedded box of the floor drain, the guide column of the embedded box of the floor drain passes through the guide column hole of the hair cleaning piece. When the floor drain is drained, the hair flows into the floor drain with the water, and the guide column diverts and guides the water flow into the sewer pipe to prevent the water flow from forming mixed water or vortex inside. Most of the hair flows into the drainage pipe along with the diverted water, thereby preventing the hair from being entangled with each other. A small part of the hair is mounted on the guide column. When the hair cleaning piece is picked up, the mounted hair is pulled away from the mounted guide column and naturally falls into the drainage pipe, thereby realizing the anti-entanglement and quick cleaning of the hair.

DETAILED DESCRIPTION

[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and the best embodiments.

[0027] As shown in the figure, the present invention comprises a floor drain pre-embedded box 1, a hair cleaning piece 2, a floor drain core 4 and a floor drain quick-release cover 5. The floor drain pre-embedded box 1, the hair cleaning piece 2 and the floor drain quick-release cover 5 are all provided with through holes in the middle. The hair cleaning piece 2 is arranged below the floor drain core 4 to prevent hair from getting tangled and knotted and affecting the sealing effect of the floor drain core 4 on the floor drain. A guide curved surface is arranged on the inner side of the hair cleaning piece 2. The vertical section of the guide curved surface includes a fastest curve. The guide curved surface is used to guide the water flow, reduce the energy loss of the water flow impact, and make the water flow velocity larger. The hair cleaning piece 2 is connected to the floor drain core 4 through a return piece, and the floor drain core 4 is sealed and connected to the floor drain quick-release cover 5 through the action of the return piece. A plurality of guide columns 12 are fixedly connected to the inner surface of the floor drain embedded box 1, and each of the guide columns 12 is arranged around the through hole of the floor drain embedded box 1. A plurality of guide column holes 11 are opened on the surface of the hair cleaning piece 2 relative to each guide column 12, and the guide column 12 is arranged to penetrate the guide column hole 11. The hair cleaning piece is connected to the floor drain embedded box 1 through a clamping piece. When the floor drain is draining, the hair flows into the floor drain with the water, and the guide column 12 diverts and guides the water flow into the sewer pipe to prevent the water flow from forming mixed water or vortex inside. Most of the hair flows along the diverted water into the drainage pipe 10, thereby preventing the hair from being entangled and knotted. A small part of the hair is mounted on the guide column 12. When the hair cleaning part 2 is picked up, the mounted hair is pulled away from the mounted guide column 12 and naturally falls into the drainage pipe 10, thereby realizing the anti-entanglement and rapid cleaning of the hair. The floor drain quick-release cover 5 is detachably connected to the floor drain embedded box 1. In this example, the side wall of the floor drain quick-release cover 5 is connected to the floor drain embedded box 1 through a special-shaped groove. The floor drain quick-release cover 5 can be removed from the floor drain embedded box 1 by rotating it at a certain angle. A cavity is formed inside the combination of the floor drain core 4, the floor drain quick-release cover 5, and the hair cleaning piece 2, and the floor drain core 4 is located above the drainage pipe 10. When the floor drain is draining, a gap is formed between the floor drain core 4 and the floor drain quick-release cover 5, wherein a first water-passing ring 15 is formed between the floor drain core 4 and the floor drain quick-release cover 5, a second water-passing ring 16 is formed between the edge of the floor drain core 4 and the inner wall of the hair cleaning piece 2, a third water-passing ring 17 is formed between the bottom of the floor drain core 4 and the guide surface of the hair cleaning piece 2, and the horizontal section of the drainage pipe 10 is a fourth water-passing surface 18. The cross-sectional areas of the first water-passing ring 15, the second water-passing ring 16, and the third water-passing ring 17 in the normal direction of the water flow direction in the cavity are approximately equal to the cross-sectional area of ​​the fourth water-passing surface 18 of the drainage pipe 10. The water-passing area does not change much when the floor drain is draining, there is no local pressure loss along the way, and the pipe can be fully drained to form a siphon drainage. During use, when the local leakage drainage is small, the system is in a gravity flow state; when the local leakage drainage fills the pipe, the water in the vertical riser in the drainage pipe 10 is affected by the acceleration of gravity, the speed increases, and a negative pressure is generated at the top, forming a siphon state.

[0028] According to the above embodiment, preferably, a protrusion 8 is fixedly connected to the bottom of the through hole of the floor drain quick release cover 5, and the protrusion 8 is arranged around the inner diameter of the through hole of the floor drain quick release cover 5. The floor drain core 4 is provided with a sealing rubber ring 7 along the circumferential direction, and the sealing rubber ring 7 is relatively arranged below the protrusion 8. The sealing rubber ring 7 is sheathed around the top of the floor drain core 4, and there is a protrusion 8 below the inner diameter of the floor drain quick release cover 5. When the floor drain water flow returns, the lifting force of the water flow on the bottom of the floor drain core 4 and the elastic force of the return member cause the sealing rubber ring 7 to press the protrusion 8 to form a line seal, which plays a role in preventing overflow, odor and insects.

[0029] According to the above embodiment, preferably, a connecting sleeve is provided in the middle of the hair cleaning piece, a positioning sleeve is provided in the middle of the lower surface of the floor drain core 4 to be sleeved with the connecting sleeve, a positioning rod 9 is fixedly connected in the positioning sleeve, and the lower end of the positioning rod 9 passes through the connecting sleeve. In this example, the return member is a spring 3, which is sleeved outside the positioning rod 9, and the two ends of the spring 3 are respectively connected to the floor drain core 4 and the hair cleaning piece 2. When draining water, the floor drain core 4 compresses the spring 3 so that there is a gap between the floor drain core 4 and the floor drain quick-release cover 5, and water is discharged from the gap into the drainage pipe 10. After drainage, the floor drain core 4 fits with the floor drain quick-release cover 5 through the action of the spring 3, thereby sealing the through hole of the floor drain quick-release cover 5, which has a better deodorizing and insect-proofing effect.

[0030] According to the above embodiment, preferably, the clamping member includes a limiting card slot 13 and a protruding slot 14, the middle of the through hole of the floor drain embedded box 1 is fixedly connected to the limiting card slot 13 through a connecting plate, and a protruding slot 14 is provided below the hair cleaning member 2, and the protruding slot 14 is clamped in the limiting card slot 13. The floor drain embedded box 1 is provided with a guide column 12 and a limiting card slot 13, and the hair cleaning member 2 is provided with a corresponding guide column hole 11 and a protruding slot 14. When the hair cleaning member 2 is installed in the floor drain embedded box 1, the protruding slot 14 is aligned with the limiting card slot 13 to be installed, and at this time, the guide column 12 can just be aligned with the guide column hole 11.

[0031] According to the above embodiment, preferably, a floor drain cover 6 is provided on the upper surface of the floor drain embedded box 1 , and the floor drain cover 6 covers the hair cleaning piece 2 , the floor drain core 4 and the floor drain quick-release cover 5 in the floor drain embedded box 1 .

[0032] The structural design of the present invention is scientific and reasonable, and it is easy to manufacture. It adopts a full-diameter pipe water flow method to form a siphon drainage, thereby realizing ultra-large flow drainage of the floor drain, which can effectively meet the large flow drainage needs and is not prone to water accumulation. At the same time, it also has good anti-odor, anti-backflow and anti-insect effects, and has a high application and promotion value.

[0033] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention.
