Description

Technical Field

[0001] This invention relates to a water-collecting device and an integrated outer pipe and inlet inner pipe bottom cover of the water-collecting device, used for connecting sanitary ware such as washbasins and sinks to drainage systems. Background Technology

[0002] There is a type of water-collecting device used to connect sanitary ware such as washbasins and sinks to the drainage system. It allows for adjustment of the water outlet height to accommodate different drain outlet heights. This device includes an inlet pipe and an outlet pipe. The inlet pipe is inserted into the outlet pipe from the top, and a removable cover is installed at the bottom or middle of the outlet pipe. With this structure, the inlet pipe is installed from the top, while the outer casing is installed from the bottom up. Consequently, when disassembling for cleaning, the inlet pipe and the outer casing must be removed separately from the top and bottom, respectively, making the operation relatively cumbersome, especially when disassembling from the top, as the connection to the sanitary ware's drainage system must also be disconnected simultaneously. Summary of the Invention

[0003] The technical problem to be solved by this invention is to address the issues existing in the prior art by providing a water-collecting device that allows for direct installation of the internal structure from the bottom, and also allows for direct operation from the bottom if the internal structure needs to be removed. To this end, this invention adopts the following technical solution:

[0004] A water-collecting device includes an outer pipe, a bottom cover, and an inner inlet pipe. The upper end of the water-collecting device has an inlet connection port, and the upper part of the outer pipe is connected to an outlet connection pipe. The inner inlet pipe and the bottom cover are integrally connected. The outer pipe has an inner pipe connection port inside it. The integral part of the bottom cover and the inner inlet pipe is installed and connected to the inner pipe connection port through the upper end of the inner inlet pipe. The bottom cover is detachably and sealingly connected to the lower end of the outer pipe. A connecting hole is provided on the lower side wall of the integral part of the bottom cover and the inner inlet pipe, and the inner inlet pipe communicates with the outer pipe through the connecting hole. The gap between the inner and outer pipes forms an outlet passage leading to the outlet connection pipe.

[0005] Furthermore, this structure of the present invention is suitable for making the appearance of metal parts out of plastic parts. That is, the water-collecting device of the present invention can be a plastic water-collecting device. The outer tube, the bottom cover, and the inner water inlet tube are all plastic parts. Since the bottom cover and the inner tube are connected as one piece, the integral part of the bottom cover and the inner water inlet tube is detachably connected to the inner tube through the upper end of the inner water inlet tube. Therefore, the surface appearance of the plastic water-collecting device is directly the whole straight tube-shaped outer tube, without seams or sections in the middle. The bottom cover does not bear the function of connection and fixation, and can be made very thin, further matching the appearance of the metal outer tube.

[0006] Based on the above technical solutions, the present invention may also employ the following further technical solutions, or combine these further technical solutions:

[0007] The upper end of the outer tube is provided with an external threaded connection section for connection with a nut.

[0008] The water inlet is inserted into a connecting pipe, the insertion depth of which is adjustable from top to bottom. The upper ends of the connecting pipe and the outer pipe are detachably fastened together and sealed. Furthermore, the sealing ring between the upper ends of the connecting pipe and the outer pipe is locked by the nut, and the insertion depth of the connecting pipe is positioned by the friction between the sealing element and the outer wall of the connecting pipe.

[0009] Inside the outer pipe, at its upper part, there is an inner pipe connection port, which is threaded and threaded to the upper end of the water inlet inner pipe.

[0010] The bottom cover has a radial rib in the middle of its bottom surface and a slot in the radial rib. The bottom surface of the bottom cover has recessed areas on both sides of the slotted rib, so that the radial rib also serves as a rotating handle.

[0011] The upper end of the connecting pipe is a threaded connection port for connecting to the drain device of the sanitary ware.

[0012] Another objective of this invention is to provide a water-receiving device assembly, which is an outer pipe that can be integrally connected to the bottom cover of the inner water inlet pipe. This allows for direct installation of the internal structure from the bottom of the water-receiving device, and if removal of the internal structure is required, it can also be done directly from the bottom of the water-receiving device. To this end, this invention adopts the following technical solution:

[0013] A water-collecting device assembly, comprising an outer tube, characterized in that the outer tube is axially continuous, with a portion at its bottom end that mates with a sealing component, an externally threaded connection section at its upper end for connection with a nut, and an inner tube connection port inside; and an outlet connection pipe interface is provided on the upper side of the outer tube.

[0014] The inner tube connection port is an internal thread, an external thread, or a snap-fit ​​interface; the bottom end of the outer tube matches the bottom cover.

[0015] Another objective of this invention is to provide a water-collecting device assembly that can be connected to the outer pipe of the water-collecting device, thereby allowing direct installation of the internal structure from the bottom. If it is necessary to dismantle the internal structure, this can also be done directly from the bottom. To this end, this invention adopts the following technical solution:

[0016] A water-collecting device assembly is characterized in that it is an integral part of the bottom cover of the water inlet inner pipe, wherein the bottom of the water inlet inner pipe is provided with a bottom cover with a diameter larger than that of the water inlet inner pipe and is integrally connected thereto, the bottom cover is provided with a part that cooperates with a sealing component, the upper end of the water inlet inner pipe is provided with a connection part that can be detachably connected to the connection port, and the lower side wall of the integral part of the bottom cover and the water inlet inner pipe is provided with a connecting hole.

[0017] The connection port is a connection port inside the outer tube that allows the inner tube to be inserted from the bottom up.

[0018] The bottom cover has a radial rib in the middle of its bottom surface and a slot in the radial rib. The bottom surface of the bottom cover has recesses on both sides of the slot, so that the radial rib also serves as a rotating handle. The bottom cover is matched with the bottom end of the outer tube into which the inner tube can be inserted from the bottom to the top.

[0019] Because of the technical solution of this invention, the internal structure of the water-receiving device can be installed directly from the bottom. If it needs to be removed, it can also be removed and pulled out directly from the bottom without having to remove its internal structure from the top. When it is necessary to clean the internal structure of the water-receiving device, the operation steps are few, it is easy to disassemble and assemble, and it is very convenient.

[0025] See attached document Figure 1-4 The present invention provides a water-collecting device, including an outer pipe 1, a bottom cover 2, and an inner water inlet pipe 3. The upper end of the water-collecting device is provided with a water inlet connection port 10. The upper part of the outer pipe 1 is connected to a water outlet connection pipe 4. The other end of the water outlet connection pipe 4 can be connected to the inlet of the drain pipe of the drainage system, such as the inlet of the drain pipe located in the corner of the wall.

[0026] This invention integrates the bottom cover 2 at the bottom end of the straight tubular inner water inlet pipe 3 with the inner water inlet pipe 3. An inner pipe connection port 15 is located inside the upper part of the outer pipe 1. The connection point to the outer pipe 1 is located at the upper end of this integrated component, i.e., the upper end of the inner water inlet pipe 3. This connection point is detachably connected to the inner pipe connection port 15. This connection can be a snap-fit, threaded connection, or other structure, allowing for one-time disassembly and assembly of the internal structure of the water-receiving device from the bottom. Furthermore, this integrated component structure can be easily manufactured using plastic injection molding, ensuring functionality while simplifying manufacturing and reducing costs. The bottom cover 2 matches the lower end diameter of the outer pipe 1, and the bottom cover 2 and outer pipe 1 are detachably and sealingly connected. The bottom cover 2 can be inserted into the lower end of the outer pipe 1. Both the bottom cover 2 and the outer pipe 1 have portions that mate with the sealing ring 5.

[0027] The upper end of the outer pipe 1 can serve as a water inlet connection 10. The water inlet connection 10 is inserted into a connecting pipe 6, which can be a component of the water-receiving device, an external accessory other than the water-receiving device, or the drain pipe of the sanitary ware drain device. The connecting pipe 6 is inserted into the inner water inlet pipe 3 from top to bottom, and its insertion depth into the inner water inlet pipe 3 can be adjusted. The inner water inlet pipe 3 and the connecting pipe 6 are in a clearance fit. A connecting hole 32 is provided on the lower side wall of the inner water inlet pipe 3. The inner water inlet pipe 3 is connected to the outer pipe 1 through the connecting hole 32. The gap 7 between the inner pipe 3 and the outer pipe 1 serves as a water outlet passage leading to the water outlet connecting pipe 4. A water storage area 100 is formed between the height of the outlet 16 where the outer pipe and the water outlet connecting pipe are connected and the lower cover 2. The connecting pipe 6 passes through the upper end 11 of the outer pipe 1 and is inserted into the inner pipe 3. The connecting pipe 6 and the upper end of the outer pipe 1 are detachably fastened together and sealed.

[0028] The upper end of the outer pipe 1 is provided with an external threaded connection section, namely the upper end 11, which is connected to the nut 8. A sealing ring 9 is provided between the upper end of the connecting pipe 6 and the outer pipe 1. After the insertion depth of the connecting pipe 6 is adjusted to the correct position, that is, after the height of the water outlet connecting pipe 4 is adjusted to the correct position, it is locked by the nut 8, thus changing the connecting pipe 6 and the outer pipe 1 from a separated state to a connected and secure state. The depth of the connecting pipe 6 inserted into the water inlet inner pipe 3 is positioned by the friction between the sealing ring 9 and the outer wall of the connecting pipe 6. Sealing the upper end of the water-collecting device between the connecting pipe 6 and the outer pipe 1 helps to connect and install the bottom cover 2 and the water inlet inner pipe 3 as a whole, and improves the overall sealing performance. At the same time, the friction of the sealing ring 9 can be used to position the insertion depth of the connecting pipe 6, and the height of the adjustable water-collecting device is positioned to stably connect with the drain hole of the drainage system.

[0029] The upper part of the outer tube 1 is provided with an inner tube connection port 15 located below the external threaded connection section and inside the outer tube 1. In this embodiment, the connection part at the upper end of the water inlet inner tube 3 is threadedly connected to the inner tube connection port 15. The upper end of the water inlet inner tube 3 is provided with an external thread 31, and the inner tube connection port 15 is provided with an internal thread that is threadedly connected to the external thread 31. Alternatively, the inner tube connection port 15 can be provided with an external thread and the upper end of the water inlet inner tube 3 can be provided with an internal thread. In this case, when the connecting tube 6 is inserted, it will enter the inner tube connection port 15 located at the upper end of the water inlet inner tube 3. This is also considered as the connecting tube 6 being inserted into the water inlet inner tube 3 from top to bottom.

[0030] To further facilitate operation, a radial rib 21 is provided in the middle of the bottom surface of the bottom cover 2, and a slot 22 is provided in the radial rib 21. The bottom surface of the bottom cover 2 has recessed areas 23 on both sides of the slot rib, so that the radial rib 21 also serves as a rotating handle. Not only can the slot be operated to operate the bottom cover 2 and the water inlet inner pipe 3 as a whole, but the radial rib can also be directly used to operate the bottom cover 2 and the water inlet inner pipe 3 as a whole by wrench or pliers. This provides greater selectivity and makes operation more convenient.

[0031] The upper end of the connecting pipe 6 is a connecting port 61 with an internal thread, which is used to connect to the drain device of the sanitary ware.

[0032] The inlet pipe 3 and the connecting pipe 6 are both straight pipes. The outlet connecting pipe 4 is a horizontal pipe connected to the outer pipe 1. The upper part of the outer pipe 1 is provided with an external threaded connection port 12 for connecting with the nut 13. The outlet connecting pipe 4 is inserted into the external threaded connection port 12 and locked with the nut 13 by the sealing ring 14, forming a separable fastened together and sealed, which can be adjusted to the connection length of the drainage system.

[0033] Reference Figure 5 The inner tube connection port 15 can also be located in the middle of the outer tube 1. The outer tube 1 contains a core tube 17 from top to bottom, with an annular gap between the core tube 17 and the outer tube 1, which also serves as an upward water outlet passage. The inner tube connection port 15 is located at the lower end of the core tube 17. The upper end of the inlet inner tube 3 is connected to the inner tube connection port 15, for example, by threaded connection or snap-fit. The bottom end of the connecting tube 6 is inserted into the core tube 17. Other parts of this embodiment are as described above. Figure 1-4 The implementation method shown.

[0034] In addition to the above implementation methods, if it is not necessary to remove the water inlet inner pipe for internal cleaning, the connection between the water inlet inner pipe and the inner pipe connection port can be set to a non-detachable connection method.
