Description

Technical Field

[0001] The utility model relates to the technical field of kitchen and bathroom, in particular to a rear telescopic drainer. Background Art

[0002] The drain outlet of the sink is usually located directly below the sink, and usually adopts a vertical corrugated pipe or drain. This installation method has the advantages of simple structure and easy installation. However, it seriously affects the storage function of the installation space under the sink. The vertically installed drain pipe occupies the middle of the entire installation space. If you want to store objects in this installation space, you have to go around and avoid the drain pipe. It is even difficult to install a partition. Often two separate E-shaped racks are purchased to serve as partitions. It can be seen that the existing drain pipe design and installation method have a significant impact on the storage of the installation space at the bottom of the sink, and even cause problems such as squeezing, uneven stacking and difficulty in taking and placing items during storage, which brings a poor user experience and needs further improvement. Utility Model Content

Implementation

[0040] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention and are not used to limit the present invention.

[0041] See also Figures 1 to 7 A rear telescopic drain includes an integrated body 1, a water inlet pipe assembly 2 and a drainage pipe 3, wherein:

[0042] The integrated body 1 is provided with a water passage cavity, a water passage joint 11 connected to the water passage cavity is provided at the top, and a water outlet joint 12 connected to the water passage cavity is provided at the bottom of the periphery. The water inlet pipe assembly 2 includes a water inlet pipe 21 and a connecting pipe 22. One end of the water inlet pipe 21 is connected to the drain outlet of the sink, and the other end is bent and extended obliquely, and is telescopically installed with the connecting pipe 22.

One end of the drainage pipe 3 is telescopically installed with the water outlet joint 12, and the other end is extended obliquely, and is bent downward at the end to form a water outlet 31.

[0043] In order to increase the range of telescopic adjustment, in one embodiment, the water joint 11 is installed with a vertically upward water inlet docking pipe 13, and is telescopically installed with the end of the connecting pipe 22. The water outlet joint 12 is installed with an obliquely extended water outlet docking pipe 14, and is telescopically installed with the front end of the drainage pipe 3. In addition, preferably, to avoid water leakage, the end of the connecting pipe 22 is telescopically inserted into the water inlet docking pipe 13, and the end of the connecting pipe 22 is sleeved with a sealing ring. The front end of the drainage pipe 3 is telescopically inserted into the water outlet docking pipe 14, and the front end of the drainage pipe 3 is sleeved with a sealing ring. The front end of the connecting pipe 22 is telescopically inserted into the end of the water inlet pipe 21, and the front end of the connecting pipe 22 is sleeved with a sealing ring.

[0044] On the basis of the above embodiment, the end of the water inlet pipe 21, the front end of the water inlet docking pipe 13 and the end periphery of the water outlet docking pipe 14 are provided with screw threads, and a fastening ring 4 for fastening is screwed in. When in use, the telescopic length of the corresponding position can be adjusted by unscrewing the fastening ring 4. When the fastening ring 4 is tightened again, as the fastening ring 4 is screwed in, the outer tube where the screw threads are located gradually shrinks and hugs the inner tube telescopically installed inside it, so that the two pipes telescopically installed at the corresponding positions can be relatively fixed to avoid shaking during use.

[0045] In one embodiment, in order to increase the function of the drain, an overflow pipe 23 extending upward is installed at the turning position of the connecting pipe 22, and an overflow cover 24 is provided on the top of the overflow pipe 23. The overflow cover 24 is provided with a docking port opening toward the side, and a screw hole extending from the overflow cover 24 is provided in the middle of the docking port. During installation, the overflow cover 24 is covered on the rear side of the overflow port of the sink, and a screw is inserted from the front side of the overflow hole and screwed into the screw hole, so that the overflow cover 24 is fixedly installed at the overflow hole, and can receive and guide the water flowing out of the overflow hole into the integrated main body 1, thereby preventing the installation space from being wet or damp.

[0046] In another embodiment, facing the application scenario of docking multiple drainage devices, the upper side of the circumference of the integrated body 1 is provided with a side interface 15 connected to the water cavity, and the side interface 15 is at least one, and is installed with a plug or a side water inlet joint 5. The side water inlet joint 5 includes a first joint 51 and a second joint 52. The first joint 51 is Y-shaped, and the front end is plugged into the side interface 15, and the end forms two branches, one branch extends obliquely upward to form a drainage joint, and the other branch forms a docking end with the same structure as the side interface 15. The second joint 52 is V-shaped, and the front end structure is the same as the front end structure of the first joint 51. The front end of the second joint 52 is plugged into the docking end of the first joint 51, and the end of the second joint 52 also forms a drainage joint. When in use, if multiple drainage devices need to be docked, multiple side interfaces 15 can be enabled. At the same time, each side interface 15 uses a side water inlet joint 5 with a double drainage joint. Of course, if only a few drainage devices need to be docked, the second joint 52 can also be inserted into the side interface 15, which is a structure of a drainage joint.

[0047] As for the specific joint of the side water inlet joint 5, further, the drain joint is installed on the side water inlet joint 5 by threaded assembly, and drain joints of different sizes can be selected according to the drainage equipment and the drainage pipe.

[0048] In order to facilitate users to check whether there is blockage, in one embodiment, the integrated body 1 is made of a transparent material, so that users can see whether there is blockage or excessive dirt accumulated inside.

[0049] In order to facilitate the cleaning of blockages, a drain port 16 is provided at the bottom of the integrated body 1, and an end cap 17 is installed on the drain port 16 by means of threads. The bottom of the end cap 17 is connected to a mounting base 18 by means of threads or snaps. When the inside of the integrated body 1 is clogged, the user can open the end cap 17 to clean out the blockage from the drain port 16. The mounting base 18 is L-shaped, and the integrated body 1 can be fixed to the ground or wall by screws or adhesives. In another embodiment, Figure 8 As shown, the mounting base 18 includes a wall clip buckle 181 and a wall clip buckle 182. The wall clip buckle 181 is arranged on the periphery of the integrated body 1. One side of the wall clip buckle 182 is connected to the wall clip buckle 181, and the other side is provided with a patch. Alternatively, as shown in FIG. Fig. 9 As shown, the mounting base 18 includes a buckle wall clip 183 and a screw patch 184. The buckle wall clip 183 is snapped into the annular groove on the upper part of the integrated body 1. The buckle wall clip 183 is installed on the wall by screws, or one end of the screw patch 184 is screwed into the screw hole of the buckle wall clip 183 by a screw, and the other end is attached to the wall by veneer.

[0050] In one embodiment, the water outlet 31 of the drainage pipe 3 is provided with a check valve 6 to prevent sewage from flowing back or odor from leaking out. In addition, a check valve 6 is also provided in the front end of the drainage pipe 3 or in the water outlet joint 12. The user can form a one-way air extraction and exhaust or water extraction and drainage effect in the drainage pipe 3 or the entire drain by stretching and squeezing the drainage pipe 3 and the water outlet joint 12, thereby clearing the blockage in the drainage pipe 3 or the entire drain. Specifically, if the check valve 6 is installed in the front end of the drainage pipe 3, when the drain is blocked, the front end of the drainage pipe 3 can be separated from the integrated body 1, and then the drainage pipe 3 can be stretched to pump air into the drain to clear the drain.

[0051] During installation, by adjusting the dimensions of the three telescopic positions, the entire drain pipe can be laid along the bottom of the sink, the back wall and the bottom of the installation space, that is, the entire drain pipe is moved backward to avoid occupying the middle part of the installation space, thereby minimizing the impact on the storage function of the installation space. At the same time, it can also improve the neatness of the installation space during storage, providing users with a better user experience.

[0052] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
