[0017] As can be seen from the above description of the present invention, compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. For the first technical solution, surface mounting is achieved by the wall of the first grouting groove being located at the bottom of the installation groove and cooperating with the supporting portion for positioning, and concealed mounting is achieved by the second positioning portion being configured to cooperate with the first positioning portion for positioning when the second supporting surface is located on the first supporting surface; since the wall of the first grouting groove is provided with water passing holes suitable for preventing mortar leakage, the mortar will not leak out during concealed mounting; after the two types of assembly are completed, a first water passing gap is formed between the wall of the first grouting groove and the wall of the installation groove to ensure drainage; the support limiting portion realizes the functions of guiding and positioning the cover body in surface mounting and the functions of positioning and supporting the cover body in concealed mounting, meeting the installation and use requirements; surface mounting and concealed mounting are achieved through the cooperation of the front and back surfaces of the base and the cover body. This solution greatly meets the needs of different users. At the same time, unifying the standardization of one product greatly improves production efficiency and stability, and effectively reduces the cost and inventory pressure brought by different models.

[0019] 2. Second technical solution: When the wall of the first grouting groove is seated on the bottom of the installation groove, the second support surface is parallel to the plane where the notch of the installation groove 1 is located and not higher than this plane, so that the cover body does not protrude. Since the cover body does not protrude, the surrounding tiles only need to be as high as the wall of the first grouting groove to complete smooth laying, reducing the use of mortar and saving costs.

[0020] 3. Third technical solution: The length of the first water passing hole of the water passing hole on the inner wall surface of the first grouting groove in the first direction is 1.2 - 2 mm, which ensures the water outlet effect and is not easy to be blocked when the floor drain is surface-mounted. The length of the water passing hole in its penetrating direction is greater than 3 mm to prevent mortar overflow when the floor drain is recessed-mounted.

[0021] 4. Fourth technical solution: The length of the water passing hole in its penetrating direction is greater than the wall thickness of the first grouting groove, ensuring the wall thickness is thin while the length of the water passing hole is longer, thus saving materials.

[0022] 5. Fifth technical solution: The length of the water passing hole in its penetrating direction is not less than 4 mm to ensure that mortar does not overflow at all when the floor drain is recessed-mounted. The angle formed by the penetrating direction of the water passing hole and the plane where the wall of the first grouting groove is located is 135 degrees to 165 degrees, realizing that the length of the water passing hole in its penetrating direction is greater than the wall thickness of the first grouting groove, and this method is easy to process.

[0023] 6. Sixth technical solution: The base includes a first wall, a second wall, a third wall, a first rib, a second rib, and a positioning rib that are integrally connected to each other and all extend in the first direction. The cover body includes a cover body, a fourth wall, and a fifth wall that are integrally connected to each other and all extend in the first direction. The cover body includes a sixth wall, enabling the floor drain to be surface-mounted and recessed-mounted. This structure is simple, saves materials, and is easy to process.

[0024] 7. Seventh technical solution: The slot is configured to be suitable for plugging into the first positioning part when the first grouting groove is seated on the bottom of the installation groove. The slot plays a role in guiding and positioning, further preventing the cover body from shaking after installation and facilitating installation.

[0025] 8. Eighth technical solution: The filter element and the cover body are connected by a connecting piece, so that when the cover body is disassembled and assembled, the filter element is taken out together, and the cover body can be held by hand to wash the filter element, preventing secondary pollution of the hand caused by dirt.

[0026] 9. Ninth technical solution: By installing an extension cover, the length of the cover body is reduced, which can increase the overall aesthetic degree, and the structure of the extension cover is simpler, easier to process, and saves costs.

[0027] 10. The tenth technical solution can meet the usage environments of floor drains at different heights by adjusting the height of the support base. When the decorated floor is uneven, it can effectively adjust the height to ensure that the overall floor drain is horizontal in all directions, and can also adjust the height to make the tiles laid on the floor drain level with the surrounding floor tiles. Moreover, since it is slidably connected to the base, multiple floor drains can be installed according to the actual length of the floor drain, and the installation position can be conveniently adjusted.

[0065] Embodiment 1:

[0066] Reference Figure 1 , Figure 1 shows a light and dark dual-purpose floor drain, including a base 1, a cover body 2, an extension cover 3, a connecting member 4, a filter member 5, an elastic member 6, an adjusting support base 7, a sealing member 8 and a floor drain core 9. In this embodiment, taking a long-strip floor drain as an example, it should be understood that it can also be applicable to a circular floor drain or other shaped floor drains.

[0067] Reference Figures 2 - 4 , the base 1 includes a first wall 11, a second wall 12, a third wall 13, a first rib 14, a second rib 15, a positioning rib 16 and a downpipe 17 that are integrated with each other and all extend along the first direction; the second wall 12 and the third wall 13 respectively extend towards each other at one end in a direction perpendicular to the second wall 12 to form flanges 121, the second wall 12 and the third wall 13 are located on both side edges of the first wall 11 and perpendicular to the first wall 11, the first wall 11, the second wall 12 and the third wall 13 enclose an installation groove 111 at the end away from the end with the flange 121, and enclose a guide rail 1211 away from the installation groove 111 at the end with the flange 121, wherein, there is a gap between the two opposite flanges 121 and they jointly form the bottom of the guide rail 1211, and the bottom of the installation groove 111 is formed by the first wall 11.

[0068] The first rib 14, the second rib 15, and the positioning rib 16 all extend from the first wall 11 in a direction parallel to the second wall 12 towards the notch of the installation groove 111 to form a support and limit portion. Among them, the first rib 14 and the second rib 15 are symmetrically located on both sides of the positioning rib 16 to form a support portion. The free ends of the first rib 14 and the second rib 15 define a first support surface 141, that is, the plane where the tops of the first rib 14 and the second rib 15 are located forms the first support surface 141, and the first support surface 141 is parallel to the plane where the notch of the installation groove 111 is located; gaps communicating with the drainage port 112 are respectively formed between the first rib 14 and the second rib 15 and the second wall 12 and the third wall 13; the positioning rib 16 is higher than the first rib 14 and the second rib 15 to form a first positioning portion.

[0069] The drain pipe 17 is integrally connected to the first wall 11 and has internal threads on its inner wall; the first wall 11 is provided with a drainage port 112 communicating with the drain pipe 17, and the drainage port 112 communicates with the gap between the support and limit portion and the installation groove 111, so that the water in the installation groove 111 can enter the drain pipe 17 through the drainage port 112 for drainage.

[0070] In this embodiment, the support portion is formed by the first rib 14 and the second rib 15, and the first positioning portion is formed by the positioning rib 16. The support portion and the first positioning portion should not be regarded as being formed by two different individuals respectively, but can also be formed by the same individual simultaneously for the support portion and the first positioning portion. For example, the support and limit portion can be formed only by the first rib 14 and the second rib 15, and the first rib 14 and the second rib 15 simultaneously form the support portion and the first positioning portion.

[0071] Reference Figure 5 、 Figure 6 Refer to

[0072] The sixth wall 23 forms a second support surface 233 parallel to the plane where the notch of the first grouting groove 232 is located on the surface facing away from the opening direction of the first grouting groove 232. The sixth wall 23 is provided with a plug-in portion protruding along the end surface facing away from the opening of the positioning groove 231. The plug-in portion is provided with a slot 234 whose opening faces away from the opening of the positioning groove 231. The opening direction of the slot 234 is the same as the opening direction of the first grouting groove 232, and the slot 234 is configured to be suitable for plugging with the first positioning portion when the groove wall of the first grouting groove 232 is seated on the bottom of the installation groove 111. In this embodiment, there are two plug-in portions, which are respectively located at both ends of the sixth wall 23 close to the edge along the first direction. The setting of the slot 234 plays a role in guiding and positioning, further preventing the shaking of the cover body 2 after installation and facilitating the installation.

[0073] Specifically, the sixth wall 23 includes a seventh wall 235, an eighth wall 236, a ninth wall 237, a tenth wall 238, and an eleventh wall 239 that are integrally connected to each other. Among them, the seventh wall 235 and the eighth wall 236 are parallel to the fourth wall 21, and the end surfaces of the tenth wall 238 and the eleventh wall 239 are on the same horizontal plane; the seventh wall 235 and the fourth wall 21 are located on both side edges of the tenth wall 238 and perpendicular to the tenth wall 238, and the eighth wall 236 and the fifth wall 22 are located on both side edges of the eleventh wall 239 and perpendicular to the eleventh wall 239; the seventh wall 235 and the eighth wall 236 are located on both side edges of the ninth wall 237 and perpendicular to the ninth wall 237 so that the seventh wall 235, the eighth wall 236, and the ninth wall 237 enclose to form a positioning groove 231 whose opening direction is opposite to the opening direction of the first grouting groove 232. The tenth wall 238 and the eleventh wall 239 form a second support surface 233 on the surface at the end where the opening of the positioning groove 231 is located. The seventh wall 235 and the eighth wall 236 extend in the direction away from the opening of the positioning groove 231 to enclose the slot 234 with the ninth wall 237, and the ninth wall 237 is the bottom wall of the slot 234 and the positioning groove 231.

[0074] Since the slot 234 is adapted to the positioning rib 16, and the positioning rib 16 forms a clearance with the drain port 112, the slot 234 does not need to extend along the first direction either. The seventh wall 235 and the eighth wall 236 only extend at both ends of the ninth wall 237 close to the edge along the first direction to form the slot 234, thus saving materials. And because the sixth wall 23 includes the seventh wall 235, the eighth wall 236, the ninth wall 237, the tenth wall 238, and the eleventh wall 239, the wall thicknesses between the walls are close to being the same and the thickness is small, which is convenient for processing and saves materials.

[0075] The sixth wall 23 is also provided with a mounting hole 24 for mounting the connecting member 4. The mounting hole 24 penetrates through the seventh wall 235, the eighth wall 236, and the ninth wall 237. Guide ribs 241 are provided on the hole wall of the mounting hole 24. The guide ribs 241 extend from the end of the hole wall facing away from the second support surface 233 towards the second support surface 233 and terminate between the two orifices of the mounting hole 24.

[0076] The fourth wall 21 and the fifth wall 22 form the wall of the first grouting groove 232. The heights of the fourth wall 21 and the fifth wall 22 are equal to the depth of the mounting groove 111. The inner surfaces of the fourth wall 21 and the fifth wall 22 are respectively adapted to cooperate with the outer surfaces of the first rib 14 and the second rib 15. When the fourth wall 21 and the fifth wall 22 are seated on the first wall 11, the slot 234 is inserted into the positioning rib 16; the wall of the first grouting groove 232 is configured to be adapted to be seated on the bottom of the mounting groove 111 and cooperate with the support portion for positioning. In this embodiment, this cooperation and positioning refer to the cooperation and positioning of the first grouting groove 232 and the support portion in the direction perpendicular to the wall of the mounting groove 111, that is, the inner surfaces of the fourth wall 21 and the fifth wall 22 are respectively adapted to cooperate with the outer surfaces of the first rib 14 and the second rib 15.

[0077] Reference Figure 4 、 Figure 7 、 Figure 8 The fourth wall 21 and the fifth wall 22 are provided with a plurality of water passing holes 211 adapted to prevent mortar leakage, and the plurality of water passing holes 211 are uniformly arranged. The length a of the water passing holes 211 in their through direction is greater than 3 mm. Since the normal diameter of mortar gravel is 0.5 - 1 mm, when the first grouting groove 232 is used for laying tiles, the position where the mortar overflows under the pressure of the gravity of the tiles is 2 - 3 times, and the overflow is 1 - 3 mm. The length a of the water passing holes 211 in their through direction is greater than 3 mm to prevent mortar overflow. Preferably, the length a of the water passing holes 211 in their through direction is not less than 4 mm to ensure that there is no overflow at all. To ensure that the water passing holes 211 can ensure the water outlet effect and are not easily blocked when the floor drain is surface-mounted, the water passing holes 211 are provided with a first water passing port 2111 on the inner wall surface of the first grouting groove 232 and a second water passing port 2112 on the outer wall surface of the first grouting groove 232. The length b of the first water passing port 2111 in the first direction is 1.2 - 2 mm. To facilitate water inlet, the length e of the second water passing port 2112 in the first direction can be greater than the length b of the first water passing port 2111 in the first direction. The through direction of the water passing holes 211 forms an angle d of 135 degrees to 165 degrees with the plane where the wall of the first grouting groove 232 is located, so as to ensure that the length of the water passing holes 211 is greater than the wall thickness of the first grouting groove 232 without changing the wall thickness of the first grouting groove 232, thereby saving materials and being convenient for processing.

[0078] In this embodiment, the wall thickness dimension c of the wall of the first grouting groove 232 is 2.5 mm. The water passing hole 211 is a straight hole. The length b of the first water passing port 2111 in the first direction is 1.5 mm. The penetrating direction of the water passing hole 211 forms an angle d of 150 degrees with the plane where the groove wall of the first grouting groove 232 is located. Thus, the length a of the water passing hole 211 in the penetrating direction is 5 mm to meet the conditions for surface-mounted and recessed installation. It should be understood that, in addition to the parallelogram shape in this embodiment, the cross-sectional shape of the water passing hole 211 can also be, but is not limited to, an arc shape or a trapezoid shape to meet the requirement that the length of the water passing hole 211 is greater than the wall thickness of the first grouting groove 232. The length of the water passing hole 211 should be understood as the length through which water flows when passing through.

[0079] Installation of the base 1 and the cover 2 in this embodiment:

[0080] Refer to Figure 9 、 Figure 10 For surface-mounted installation, the groove wall of the first grouting groove 232 is seated on the bottom of the installation groove 111 and cooperates with the support portion for positioning. The specific operation is that the slot 234 and the positioning rib 16 are first inserted. The first grouting groove 232 is guided by the first rib 14 and the second rib 15 until the groove wall of the first grouting groove 232 is seated on the bottom of the installation groove 111. At this time, the cooperation and positioning between the first grouting groove 232 and the support portion are completed. The slot 234 and the positioning rib 16 are completely inserted, and a first water passing gap 18 is formed between the groove wall of the first grouting groove 232 and the groove wall of the installation groove 111, so that water can flow into the installation groove 111 through the first water passing gap 18, pass through the water passing hole 211, and then be discharged from the drain port 112. Since the height of the groove wall of the first grouting groove 232 is equal to the depth of the installation groove 111 and the height of the support and limit portion is less than the depth of the first grouting groove 232, when the groove wall of the first grouting groove 232 is seated on the bottom of the installation groove 111, the second support surface 233 and the plane where the notch of the installation groove 111 is located are on the same plane, and the cover 2 does not protrude, and the upper end of the floor drain is flat, so that it will not cause bumps to the user. After assembly, the water on the positioning groove 231 can flow along the gap between the cover 2 and the base 1 or the extension cover to the base 1 to achieve drainage. In surface-mounted installation, the support and limit portion realizes the functions of guiding and positioning the cover 2 by cooperating with the groove wall of the first grouting groove 232 for positioning and inserting into the slot 234.

[0081] Refer to Figure 11 、 Figure 12Flush-mounted installation: The second support surface 233 is located on the first support surface 141. The specific operation is to first install the positioning groove 231 and the positioning rib 16 until the second support surface 233 is located on the first support surface 141. At this time, the positioning groove 231 and the positioning rib 16 are fully engaged for positioning. The first rib 14 and the second rib 15 abut against the second support surface 233 to support the cover body 2, preventing the cover body 2 from tilting due to excessive mortar weight without support, which may affect its use. Since the cover body 2 used for both flush-mounted and surface-mounted installations is the same, the first water passing gap 18 formed during surface-mounted installation is also correspondingly formed during flush-mounted installation. The first water passing gap 18 communicates with the drain opening 112 to ensure drainage. During flush-mounted installation, the support and limit portion realizes the functions of positioning and supporting the cover body 2 by cooperating with the positioning groove 231 and abutting against the second support surface 233.

[0082] The cover body 2 and the base 1 of this structure can be installed in both surface-mounted and flush-mounted manners. The installation process is simple and efficient, and the product is easy to process. Preferably, both the cover body 2 and the base 1 are made of composite plastic materials, with good strength, high yield rate, high production efficiency, easy to cut, and no sparks generated, effectively eliminating the fire hazard during the cutting process. At the same time, the cost is only 1 / 10 of that of metal materials, greatly reducing the cost.

[0083] Reference Figure 13 、 Figure 14 Furthermore, the surface-mounted and flush-mounted floor drain also includes an extension cover 3. The extension cover 3 is provided with a second grouting groove 31 extending in the first direction, a third support surface 32, and a third positioning portion 33. The second grouting groove 31 is configured to be located on the bottom of the installation groove 111 and cooperate with the support portion for positioning and form a second water passing gap 34 with the wall of the installation groove 111. The third support surface 32 faces away from the opening direction of the second grouting groove 31 and is parallel to the plane where the opening of the second grouting groove 31 is located. The third positioning portion 33 is configured to cooperate with the first positioning portion for positioning when the third support surface 32 is located on the first support surface 141.

[0084] Reference Figure 9 、 Figure 11 、 Figure 15 、 Figure 16 In this embodiment, there are two extension covers 3, which are installed on the base 1 and respectively abut against both ends of the cover body 2. The difference in its structure from the cover body 2 is only that it does not have a water passing hole 211 and an installation hole 24, and its insertion slot 234 can extend in the first direction to ensure firm insertion. Its installation method is the same as that of the cover body 2, thus realizing both surface-mounted and flush-mounted installations, which will not be elaborated here. In this embodiment, since the long-strip floor drain only has a water passing hole 211 on the cover body 2, and the position of the cover body 2 corresponds to that of the drain opening 112. If the cover body 2 is processed very long, the cost is high and it is not easy to disassemble and clean. By installing the extension cover 3, the length of the cover body 2 is reduced, the overall aesthetic degree can be increased, and the structure of the extension cover 3 is simpler, which is convenient for processing and saves costs.

[0085] Reference Figure 17 The connecting member 4 includes a connecting screw 41, a connecting head 42 and a guide rod 43. The connecting screw 41 is used to connect the guide rod 43 and the connecting head 42.

Specifically, a guide groove 421 adapted to the guide rib 241 is provided on its outer side wall. The guide groove 421 is formed by a first guide groove 4211 and a second guide groove 4212 that are perpendicular to each other and communicate with each other. Among them, the extending direction of the first guide groove 4211 is parallel to the extending direction of the guide rib 241. The guide rib 241 is configured to be first slid into the first guide groove 4211 and then into the second guide groove 4212 for limiting. A water passing groove 422 having the same shape as the positioning groove 231 is also provided at the top end of the connecting head 42. The water passing groove 422 is configured for surface-mounted floor drain and coincides with the positioning groove 231 when the guide groove 421 and the guide rib 241 are cooperatively limited, ensuring the overall appearance and ensuring the drainage of the positioning groove 231. The connecting head 42 also has a spring mounting groove 4241 and a threaded groove 4242 for cooperating with the connecting screw 41.

[0087] Reference Figure 19 Specifically, the connecting head 42 is generally cylindrical, and it includes a cylindrical body 423 and an annular wall 424 that are integrally connected. The cylindrical body 423 has an opening. The guide groove 421 is provided on the outer side wall of the cylindrical body 423. The cylindrical body 423 is recessed on the end surface facing away from the opening of the cylindrical body 423 in the direction of the opening of the cylindrical body 423 with a water passing groove 422 extending in the first direction. The annular wall 424 extends from the middle of the bottom wall of the water passing groove 422 in the direction of the opening of the cylindrical body 423. The outer wall of the annular wall 424 and the inner wall of the cylindrical body 423 enclose to form a spring mounting groove 4241, and the inner wall of the annular wall 424 and the bottom wall of the water passing groove 422 form a threaded groove 4242.

[0088] Reference Figure 17 The guide rod 43 includes a first rod 431 and a head 432 that are integrally connected. The head 432 is formed by circumferentially extending from one end of the first rod 431. Among them, the first rod 431 forms a guiding portion, and the guiding portion is used for sliding cooperation with the filter element 5 so that when the cover body 2 covers the base 1, the filter element 5 acts on the drain port 112; the head 432 forms a filter element limiting portion, and the filter element limiting portion is configured to be adapted to extend into the drain port 112 and is used to prevent the filter element 5 from detaching from the connecting member 4.

[0089] Reference Figure 17, the filter element 5, the filter element 5 is a filter screen, which is formed by a longitudinal rib and a plurality of transverse ribs perpendicular to the longitudinal rib connected as a whole, and has a notch 51 at the periphery for cleaning dirt. The filter screen is provided with a filter screen mounting hole 52, and the filter screen mounting hole 52 penetrates the longitudinal rib for the first rod 431 to pass through so that the filter screen is slidably arranged on the connecting piece 4. The diameter of the filter screen mounting hole 52 is smaller than the size of the end 432 of the guide rod 43 so that the filter screen is limited at this end; the first limiting surface 53 is formed on the end face of the filter screen facing the cover body 2, and the connecting piece 4 or the cover body 2 is provided with a second limiting surface 42411 facing the first limiting surface 53. In this embodiment, the bottom of the spring mounting groove 4241 of the connecting head 42 forms the second limiting surface 42411.

[0090] Reference Figure 17 , the elastic member 6, the elastic member 6 is a spring, which is located between the first limiting surface 53 and the second limiting surface 42411 and is used to drive the filter element 5 to move in the direction towards the end 432.

[0091] During installation, refer to Figure 10 、 Figure 12 , first, the filter screen is sleeved on the guide rod 43, then the spring is sleeved on the guide rod 43, and the connecting head 42 is installed in the mounting hole 24 of the cover body 2. At this time, the guiding rib 241 enters the first guiding groove 4211 and abuts against the connection of the first guiding groove 4211 and the second guiding groove 4212; then the guide rod 43 and the connecting head 42 are fixedly connected by the connecting screw 41, and the spring is compressed; during the fixing process of the connecting screw 41, the connecting head 42 will be driven to rotate, so that the guiding rib 241 enters the second guiding groove 4212 from the first guiding groove 4211. When the filter screen and the cover body 2 are connected, the spring abuts against the filter screen at one end and the bottom of the spring mounting groove 4241 at the other end. When the cover body 2 is covered on the base 1, the guiding part of the guide rod 43 guides the installation of the filter screen so that the filter screen acts on the drain port 112, and the end 432 extends into the drain port 112. Since the spring after installation is compressed, it drives the filter screen to move in the direction away from the cover body 2, so that the filter screen is closely attached to the drain port 112 to prevent displacement. Since the cover body 2 and the filter screen are connected via the connecting piece 4, the cover body 2 can be held by hand to wash the filter screen, and the filter screen has a notch 51 at the periphery, and the dirt can be washed off by tilting and using water, which is convenient to use and prevents secondary pollution of the hand caused by dirt.

[0092] Reference Figure 10 、 Figure 12 , preferably, the guide rod 43 extends further towards the drain port 112, that is, the first rod 431 is further extended. When the cover body 2 is covered on the base 1, the end 432 extends into the drain port 112 and forms a gap with the filter screen. After disassembly in this state, the filter screen moves to the end 432 of the guide rod 43 due to the release of the spring force, and the distance between the filter screen and the cover body 2 will be greater, further preventing secondary pollution. It should be understood that in addition to being attached to the drain port 112, the filter screen can also be configured to be attached to the floor drain core 9 to achieve the same function. Refer toFigure 20 , Figure 21 Through the cooperation of the guide rib 241 on the cover body 2 and the guide groove 421 of the connector 42, this method can realize the installation of the connector 42 in both open and concealed installation, thereby ensuring the fixation of the filter.
