Description

Technical Field

[0001] The utility model relates to the technical field of floor drain equipment, and more specifically, to a floor drain joint and a drainage device thereof. Background Art

[0002] Traditional HDPE same-floor drainage means that the drainage pipes of sanitary appliances in the bathroom do not pass through the floor slab, and the drainage transverse pipe is connected to the drainage main pipe in the same layer. Once a situation that needs to be cleared and unblocked occurs, the problem can be solved in the same layer. Compared with the different-layer drainage system, the same-layer drainage system can get rid of the constraints between adjacent floors through the reasonable layout of the pipes in the same layer, avoiding a series of troubles and hidden dangers caused by the drainage transverse pipe occupying the lower layer space.

[0003] In bathrooms with same-floor drainage systems, in order to meet the needs of floor showers, the current existing technology is to install a direct-buried water-sealed floor drain, but this will increase the complexity of construction and potential leakage points. At the same time, in order to prevent odor from flowing back into the system, the structural floor needs to be treated with a micro-drop board, which affects the user experience. Although the structural layer was waterproofed twice during the construction phase, some ground drainage may still leak into the structural layer through the edge of the floor drain, the landfill layer, etc., which may cause mold on the floor or surrounding walls in the long run. In addition, after the micro-drop board treatment, the effective height between floors is affected, reducing the user's comfort.

[0004] At present, there is a same-floor drainage system that uses a floor drain joint to replace part of the functions of a direct-buried water-sealed floor drain, thereby avoiding laying a landfill layer and thus avoiding compressing the actual floor height between floor slabs. However, the floor drain joint disclosed in the above solution has an unsatisfactory drainage effect and is prone to water leakage. Utility Model Content

The height of the conducting position between the conducting connector 2 and the receiving member 3 is lower than the height of the conducting position between the receiving member 3 and the drainage channel 11. In this embodiment, there is one drainage channel 11 and two water inlet channels 12. The diameter of the pipe of the drainage channel 11 is greater than the diameter of the pipe of the water inlet channel 12.

In this embodiment, there are four drainage holes 32, and the distance between the lowest end face of the drainage hole 32 and the lowest end face of the water storage chamber 33 is greater than 50 cm, so that the water seal depth in the water storage chamber 33 is correspondingly greater than 50 cm, thereby ensuring the water seal stability of the floor drain joint 10.

[0039] Embodiment 2

[0040] This embodiment is similar to the first embodiment, except that Figure 2 and Figure 5 As shown, this embodiment also includes a limiter 4 disposed in the connector body 1, through which the conductive connector 2 is detachably connected to the inner side of the connector body 1, and the limiter 4 abuts against the conductive connector 2. The limiter 4 is used to limit the conductive connector 2 to prevent it from axial displacement.

[0041] The limiting member 4 is provided with a second knob 41 and a plurality of through holes 42, and the water inlet channel 12 is connected to the conductive connector 2 through the through holes 42. The second knob 41 is provided to facilitate the disassembly and assembly of the limiting member 4. In this embodiment, the limiting member 4 is an annular structure, and the second knob 41 is connected to the annular structure, and this arrangement makes the through holes 42 constitute two semicircular through holes.

The first cover body 5 is detachably connected to the joint body 1. When the floor drain joint 10 needs to be repaired or cleaned, it is only necessary to unscrew the first cover body 5 to clean the inside of the floor drain joint 10 or replace damaged parts. In addition, the setting of the first cover body 5 can also effectively prevent the floor drain joint 10 from being polluted by the external environment, thereby ensuring the sealing and safety of the floor drain joint 10; the first rotary handle 51 is set to facilitate the disassembly and assembly of the first cover body 5; the setting of the connecting cavity 8 can increase the drainage performance of the floor drain joint 10. When sewage flows into the floor drain joint 10 from the water inlet channel 12, the sewage will first enter the connecting cavity 8, and then flow out through the through hole 42. This setting can ensure that the sewage can be discharged smoothly and reduce the occurrence of blockage.

[0044] Preferably, a second sealing ring 9 is further provided on the first cover body 5, and the first cover body 5 is sealed and connected to the inspection port 7 via the second sealing ring 9. This arrangement can improve the sealing performance of the floor drain joint 10.

[0045] The working principle of a floor drain joint of the utility model is:

[0046] When sewage flows in from the water inlet channel 12, it will first enter the connecting chamber 8. The setting of the connecting chamber 8 can increase the drainage performance of the floor drain joint 10, can effectively guide the sewage into the floor drain joint 10, and can also make the sewage more evenly distributed after entering the floor drain joint 10, thereby improving the drainage efficiency. Thereafter, the sewage will flow into the connecting pipe 22 through the through hole 42, and the sewage will eventually flow into the water storage chamber 33 and form a water seal of a certain height. When the water seal in the water storage chamber 33 reaches a certain height, the excess sewage will flow from the drainage hole 31 to the drainage pipe, thereby completing the drainage.

[0047] When the floor drain connector 10 needs to be repaired or cleaned, the first cover 5 is unscrewed by the first handle 51, and the annular structure is unscrewed by the second handle 41 to take out the receiving member 3 and the conducting connector 2, which is convenient and quick. The floor drain connector of the utility model can facilitate the repair and cleaning of the floor drain connector 10 while ensuring the hygiene and reliability of the drainage device.

[0048] Embodiment 3

The setting of the screen 30 can effectively filter out the debris in the sewage and ensure the smoothness of the drainage.

[0050] Specifically, the connection method between the connecting pipe 20 and the water inlet channel 12 can be threaded connection, flange connection, welding, etc., which is selected according to the actual application scenario.

[0051] In this embodiment, the floor drain joint 10 can be conveniently connected to the existing drainage pipe and prevent sewage leakage. The connection between the connecting pipe 20 and the water inlet channel 12 can be sealed with a sealing ring or other sealing member to ensure the sealing of the drainage.

[0052] As a preferred embodiment, a valve can be provided on the connecting pipe 20 to control the switch of the drainage device. When drainage is required, the valve can be opened to ensure smooth drainage; when drainage is not required, the valve can be closed to prevent sewage leakage.

[0053] The working principle of a drainage device of the utility model is:

[0054] When drainage is required, the valve is opened, and the sewage flows through the screen 30 to filter out debris and enter the connecting pipe 20, and then enters the floor drain joint 10. Due to the setting of the screen 30, the debris in the sewage can be effectively filtered out to ensure the smoothness of drainage; when drainage is not required, the valve is closed to prevent sewage leakage. The utility model provides a drainage device with the advantages of simple structure, easy use, good filtering effect, and good sealing, and is suitable for places where drainage is required, such as homes and public places. At the same time, the aperture and number of the screen 30 can be adjusted according to actual needs to meet the drainage needs of different occasions.
