[0030] The technical solution of the utility model is further described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0031] Example 1: Figures 1 to 7 A displaceable eccentric drainage floor drain is shown, comprising a floor drain assembly 1 and a panel assembly 2, wherein the floor drain assembly 1 comprises a floor drain body 1.2 and a floor drain end cover 1.1, wherein the overall shape of the floor drain body is cylindrical, and two drainage openings 1.2.2 are symmetrically distributed on the outside of the floor drain body, and the upper part of the floor drain body is a circular opening, and the floor drain end cover is installed on the circular opening of the floor drain body, and the floor drain body and the floor drain end cover are welded or connected in other ways to form a whole. An installation groove 1.1.1 is provided on the upper side of the floor drain end cover, and the installation groove is a circular groove and is recessed inside the floor drain body, and the bottom of the installation groove is a circular through-hole structure, wherein the diameter of the through-hole is smaller than the diameter of the installation groove, thereby forming a fixed step 1.1.2 in the installation groove.

[0032] A cylindrical sleeve 3 is arranged in the installation groove. The sleeve is a hollow cylindrical structure. One end of the sleeve abuts against the fixed step, and the other end is provided with a panel assembly. One end of the sleeve is an open hole structure, and the other end is provided with a closed mounting plate 3.2. The open hole end of the sleeve abuts against the installation groove, and the interior of the sleeve is connected with the interior of the floor drain body. The panel assembly can be installed on the closed mounting plate at the other end. The closed mounting plate of the sleeve is located in the axial hole of the sleeve, and the distance from the closed mounting plate to the upper end of the sleeve is 2mm to protect the closed mounting plate on the sleeve from damage. In actual use, it is necessary to open a blind hole 3.2.1 on the closed mounting plate according to actual conditions to match the panel assembly. Since the mounting hole can be opened at any position on the closed mounting plate, the radial position of the panel assembly can be adjusted according to the actual construction conditions to compensate for the actual construction deviation of the panel assembly.

[0033] In the actual construction process (taking the construction and installation of bathroom floor drain as an example), the panel assembly and the floor drain assembly are separated independently. First, the floor drain assembly and the sleeve need to be pre-buried in the lower floor layer of the bathroom. The drain outlet on the floor drain body is connected to the drainage pipe of the drainage system of the bathroom floor to ensure smooth drainage of the floor drain assembly. When laying the tile floor in the later stage, the surface of the panel assembly is made slightly lower than the tile floor. A sealing rubber ring is arranged on the side of the sleeve close to the open end to achieve the sealing between the sleeve and the installation groove. In order to ensure the sealing effect between the sleeve and the installation groove, two sealing rubber rings can be arranged. The sleeve is a hard tube structure, and the sleeve and the installation groove are interference fit to ensure the installation strength between the sleeve and the installation groove.

[0034] Among them, after the sleeve and the installation groove on the floor drain end cover are fixed, the floor drain assembly and the sleeve can be buried in the soil, but the closed mounting plate on the sleeve needs to be exposed. When the bathroom tiles are laid, an area needs to be reserved for the laying of the panel assembly. At this time, according to the fitting position of the panel assembly and the surrounding tiles, a blind hole is opened on the closed mounting plate on the sleeve, and then the panel assembly is installed so that the panel assembly is seamlessly connected with the surrounding tiles, thereby completing the installation and laying of the floor drain.

[0035] In this embodiment, the panel assembly includes a panel base 2.2 and a floor drain panel 2.1. The panel base is directly connected to the closed mounting plate on the sleeve, and the floor drain panel corresponds to the position of the floor tiles of the bathroom (or slightly lower than the tile surface, or flush with the tile surface); the panel base includes a first mounting portion 2.2.1 and a second mounting portion 2.2.2. The first mounting portion is arranged on the upper side of the panel base, and the second mounting portion is arranged on the lower side of the panel base. The first mounting portion and the second mounting portion are both hollow cylindrical structures, and a partition 2.2.3 structure is arranged between the first mounting portion and the second mounting portion. The partition can be square or circular. The radial dimension of the partition is larger than the radial dimension of the first mounting portion, providing a support surface for the first mounting portion. The radial dimension of the first mounting portion is larger than the radial dimension of the second mounting portion. The first mounting portion and the second mounting portion are connected to ensure the drainage effect of the panel assembly. The floor drain panel is also provided with a plurality of water holes 2.1.1 for drainage of the bathroom.

[0036] The first mounting portion is used to assemble with the floor drain panel, specifically, Figure 2 As shown, the upper side of the first mounting part is provided with an annular bevel, and the edge of the corresponding floor drain panel is provided with an annular bevel. The bevel of the first mounting part cooperates with the bevel on the floor drain panel to complete the detachable assembly. The second mounting part is used to cooperate with the closed mounting plate on the sleeve. A standard hole opener can be used to open a blind hole on the closed mounting plate. The blind hole and the second mounting part are also interference fit to ensure the connection strength between the second mounting part and the blind hole. A sealing groove 2.2.2.1 is provided on the circumferential outer surface of the second mounting part. The sealing groove corresponds to the position of the closed mounting plate, and a sealing rubber ring is provided in the sealing groove to ensure the sealing effect between the second mounting part and the closed mounting plate.

[0037] An anti-return sleeve 5 structure is also provided in the second installation part. The anti-return sleeve is a hollow cylindrical structure. One end of the anti-return sleeve is sealed and connected to the inner side of the second installation part, and the other end extends to the inside of the floor drain body. It mainly plays a role in drainage. Two limiting steps 1.2.1 are provided at the bottom of the floor drain body and on the inner side of the floor drain body. Figure 2 or Figure 4 As shown, the limiting steps are in the form of two thin sheet structures, which abut against the bottom of the anti-return sleeve, thereby limiting and fixing the anti-return sleeve to prevent the anti-return sleeve from falling into the floor drain body, and since the limiting steps are in the form of thin sheet structures, they will not affect the drainage effect of the anti-return sleeve.

[0038] like Figure 2 or Figure 4As shown, a water seal side wall 1.2.4 is also arranged inside the floor drain body, and the height of the water seal side wall is higher than the bottom position of the installation groove, which is used to form a water seal to prevent backflow. When the floor drain is draining, water first flows from the floor drain panel into the anti-backflow sleeve, and then enters the interior of the floor drain body, and the water level in the floor drain body gradually rises to the top of the water seal side wall. When the water level is flush with the water seal side wall, the excess water is discharged from the drainage ports on both sides into the drainage system of the bathroom. At the same time, some water is still retained inside the floor drain body, and the water level is maintained at the top of the water seal side wall. The water forms a water cover between the water seal side wall and the installation groove to prevent the odor in the drainage system from gushing out, thus preventing backflow.

[0039] like Figure 2 or Figure 6 As shown, an anti-backflow component 4 is also arranged on the top of the anti-backflow sleeve, and the anti-backflow component includes a filter screen 4.1 and a floor drain anti-backflow 4.2. The filter screen is in the shape of a disc and is clamped on the partition of the panel assembly. The floor drain anti-backflow is a filter element. The floor drain anti-backflow is arranged on the lower side of the filter screen, and the floor drain anti-backflow is located in the anti-backflow sleeve, which plays a role in filtering debris from the floor drain, preventing debris from entering the floor drain assembly and blocking the floor drain.

[0040] like Figure 6 or Figure 7 As shown, two mounting holes 5.1 are provided on the top of the anti-return sleeve, and the mounting holes are symmetrically arranged on both sides of the anti-return sleeve. An anti-return handle 5.2 is fixed on the mounting hole. The anti-return handle is curved, and both ends of the anti-return handle are hooked on the mounting hole. After filtering a lot of debris on the floor drain anti-return, when cleaning it, the anti-return component can be taken out through the anti-return handle, which is convenient for maintenance and cleaning; at the same time, because the anti-return handle also hooks the anti-return sleeve, it can also prevent the anti-return sleeve from falling into the inside of the floor drain body.

[0041] Example 2: Figures 1 to 8 A displaceable eccentric drainage floor drain is shown, comprising a floor drain assembly 1 and a panel assembly 2, wherein the floor drain assembly 1 comprises a floor drain body 1.2 and a floor drain end cover 1.1, wherein the overall shape of the floor drain body is cylindrical, and two drainage openings 1.2.2 are symmetrically distributed on the outside of the floor drain body, and the upper part of the floor drain body is a circular opening, and the floor drain end cover is installed on the circular opening of the floor drain body, and the floor drain body and the floor drain end cover are welded or connected in other ways to form a whole. An installation groove 1.1.1 is provided on the upper side of the floor drain end cover, and the installation groove is a circular groove and is recessed inside the floor drain body, and the bottom of the installation groove is a circular through-hole structure, wherein the diameter of the through-hole is smaller than the diameter of the installation groove, thereby forming a fixed step 1.1.2 in the installation groove.

[0042] like Figure 2 and Figure 8As shown, a cylindrical sleeve 3 is arranged in the installation groove. The sleeve is a hollow cylindrical structure. One end of the sleeve is abutted against the fixed step, and the other end is provided with a panel assembly; an annular groove 3.1 is arranged on the outer surface of the sleeve. The grooves are continuously distributed on the outer side of the sleeve and form a parallel groove structure, wherein the interval between the grooves is small, and the interval can be set between 1mm and 3mm. In this embodiment, the interval between the grooves is 2mm. The sleeve is detachably connected to the floor drain end cover, and the height of the sleeve is greater than or equal to the groove depth of the installation groove; the height of the sleeve is different, that is, the actual installation height of the panel assembly can be changed. When the axial length of the sleeve is consistent with the groove depth of the installation groove, it means that the actual installation height of the panel assembly is suitable for the ground surface height. When the axial length of the sleeve is greater than the groove depth of the installation groove, it means that the actual installation position of the panel assembly will be lower than the ground surface height, and the installation height of the panel assembly needs to be adjusted through the sleeve.

[0043] Among them, a sealing rubber ring can be installed in the groove to ensure the sealing effect between the sleeve and the installation groove of the floor drain end cover to prevent water from seeping into the soil structure from the floor drain assembly; at the same time, the groove is also conducive to the cutting of the sleeve, which is used to adjust the axial length of the sleeve. The sleeve can be cut quickly and neatly along the position of the groove to ensure the coordination effect between the sleeve and the installation groove. The intervals between the grooves are small, so that the axial length of the sleeve can be adjusted in a small range. Specifically, when a layer of grooves is cut off, the axial length of the sleeve can be shortened by 2mm to adapt to the small-range installation position deviation of the panel assembly from the ground.

[0044] One end of the sleeve is an open hole structure, and the other end is provided with a closed mounting plate 3.2. The open hole end of the sleeve abuts against the mounting groove, and the interior of the sleeve is connected to the interior of the floor drain body; and the panel assembly can be installed on the closed mounting plate at the other end. The closed mounting plate of the sleeve is located in the axial hole of the sleeve, and the distance from the closed mounting plate to the upper end of the sleeve is 2mm to protect the closed mounting plate on the sleeve from damage; in actual use, it is necessary to open a blind hole 3.2.1 on the closed mounting plate according to the actual situation to match the panel assembly; since the mounting hole can be opened at any position on the closed mounting plate, the radial position of the panel assembly can be adjusted according to the actual construction situation to compensate for the actual construction deviation of the panel assembly.

[0045] In the actual construction process (taking the construction and installation of bathroom floor drains as an example), the sleeve and the floor drain end cover are separated independently. First, the floor drain assembly needs to be pre-buried in the lower floor layer of the bathroom, and the drain outlet on the floor drain body is connected to the drainage pipeline of the drainage system of the bathroom floor to ensure smooth drainage of the floor drain assembly. When laying the tile floor in the later stage, the length of the heightening sleeve is cut according to the actual position of the floor drain end cover and the expected tile laying height, so that the surface of the panel assembly is slightly lower than the tile floor; and the cut end of the sleeve can only be the open end of the sleeve. By cutting the groove at the open end of the sleeve, not only the sleeve can be changed The axial length of the sleeve will not affect the normal use function of the sleeve, and the closed mounting plate is retained for the installation of the panel assembly; after the cutting of the sleeve is completed, a sealing rubber ring is arranged in the groove on the side of the sleeve close to the open end (the open end after cutting). In order to ensure the sealing effect, sealing rubber rings can be arranged in multiple grooves. In this embodiment, sealing rubber rings are arranged in two grooves, and the grooves for setting the sealing rubber rings are all located in the mounting groove; then the open end of the sleeve is abutted against the fixed step on the mounting groove. The sleeve is a hard tube structure, and there is an interference fit between the sleeve and the mounting groove, thereby ensuring the installation strength between the sleeve and the mounting groove.

[0046] After the sleeve and the mounting groove on the floor drain end cover are fixed, the floor drain assembly and sleeve can be buried in the soil, but the closed mounting plate on the sleeve needs to be exposed. When the bathroom tiles are laid, an area needs to be reserved for the laying of the panel assembly. At this time, according to the fit between the panel assembly and the surrounding tiles, a blind hole is opened on the closed mounting plate on the sleeve, and then the panel assembly is installed so that the panel assembly is seamlessly connected with the surrounding tiles, thereby completing the installation and laying of the floor drain.

[0047] In this embodiment, the panel assembly includes a panel base 2.2 and a floor drain panel 2.1. The panel base is directly connected to the closed mounting plate on the sleeve, and the floor drain panel corresponds to the position of the floor tiles of the bathroom (or slightly lower than the tile surface, or flush with the tile surface); the panel base includes a first mounting portion 2.2.1 and a second mounting portion 2.2.2. The first mounting portion is arranged on the upper side of the panel base, and the second mounting portion is arranged on the lower side of the panel base. The first mounting portion and the second mounting portion are both hollow cylindrical structures, and a partition 2.2.3 structure is arranged between the first mounting portion and the second mounting portion. The partition can be square or circular. The radial dimension of the partition is larger than the radial dimension of the first mounting portion, providing a support surface for the first mounting portion. The radial dimension of the first mounting portion is larger than the radial dimension of the second mounting portion. The first mounting portion and the second mounting portion are connected to ensure the drainage effect of the panel assembly. The floor drain panel is also provided with a plurality of water holes 2.1.1 for drainage of the bathroom.

[0048] The first mounting portion is used to assemble with the floor drain panel, specifically, Figure 2As shown, the upper side of the first mounting part is provided with an annular bevel, and the edge of the corresponding floor drain panel is provided with an annular bevel. The bevel of the first mounting part cooperates with the bevel on the floor drain panel to complete the detachable assembly. The second mounting part is used to cooperate with the closed mounting plate on the sleeve. A standard hole opener can be used to open a blind hole on the closed mounting plate. The blind hole and the second mounting part are also interference fit to ensure the connection strength between the second mounting part and the blind hole. A sealing groove 2.2.2.1 is provided on the circumferential outer surface of the second mounting part. The sealing groove corresponds to the position of the closed mounting plate, and a sealing rubber ring is provided in the sealing groove to ensure the sealing effect between the second mounting part and the closed mounting plate.

[0049] An anti-return sleeve 5 structure is also provided in the second installation part. The anti-return sleeve is a hollow cylindrical structure. One end of the anti-return sleeve is sealed and connected to the inner side of the second installation part, and the other end extends to the inside of the floor drain body. It mainly plays a role in drainage. Two limiting steps 1.2.1 are provided at the bottom of the floor drain body and on the inner side of the floor drain body. Figure 2 or Figure 4 As shown, the limiting steps are in the form of two thin sheet structures, which abut against the bottom of the anti-return sleeve, thereby limiting and fixing the anti-return sleeve to prevent the anti-return sleeve from falling into the floor drain body, and since the limiting steps are in the form of thin sheet structures, they will not affect the drainage effect of the anti-return sleeve.

[0050] like Figure 2 or Figure 4 As shown, a water seal side wall 1.2.4 is also arranged inside the floor drain body, and the height of the water seal side wall is higher than the bottom position of the installation groove, which is used to form a water seal to prevent backflow. When the floor drain is draining, water first flows from the floor drain panel into the anti-backflow sleeve, and then enters the interior of the floor drain body, and the water level in the floor drain body gradually rises to the top of the water seal side wall. When the water level is flush with the water seal side wall, the excess water is discharged from the drainage ports on both sides into the drainage system of the bathroom. At the same time, some water is still retained inside the floor drain body, and the water level is maintained at the top of the water seal side wall. The water forms a water cover between the water seal side wall and the installation groove to prevent the odor in the drainage system from gushing out, thus preventing backflow.

[0051] like Figure 2 or Figure 6 As shown, an anti-backflow component 4 is also arranged on the top of the anti-backflow sleeve, and the anti-backflow component includes a filter screen 4.1 and a floor drain anti-backflow 4.2. The filter screen is in the shape of a disc and is clamped on the partition of the panel assembly. The floor drain anti-backflow is a filter element. The floor drain anti-backflow is arranged on the lower side of the filter screen, and the floor drain anti-backflow is located in the anti-backflow sleeve, which plays a role in filtering debris from the floor drain, preventing debris from entering the floor drain assembly and blocking the floor drain.
