Description

[0001] DESCRIPTION

[0002] Improved toilet drain device

[0003] OBJECT OF THE INVENTION

[0004] The invention, as the title of this specification indicates, is an improved toilet drainage device. It is an innovation that, within current techniques, offers advantages previously unknown.

[0005] TECHNICAL SECTOR

[0006] The present invention falls within the sector of fixed constructions in water supply and water evacuation, especially in toilets or urinals with water discharge system, as well as in other constituent elements of toilets (joints or connections of pipes in general).

[0007] Similarly, in elements or constituent parts of cups, particular adaptations of joints or couplings of tubes for their use in the cups.

[0008] STATE OF THE ART

[0009] The present invention arises as an improvement to conventional toilet drainage systems, which present problems of leaks, liquid leakage and bad odors due to the lack of an efficient seal between the drain pipe and the toilet.

[0010] Traditional systems, in many cases, use connections that do not always guarantee a hermetic seal, and, in addition, the parts are not versatile enough to adapt to different types of installations and sizes.

[0011] Accordingly, this invention provides an improved toilet drain device that optimizes the installation and operation of toilet drainage systems by offering several important advantages, such as improved watertightness, adaptability to different installations, and ease of maintenance. Currently, no improved toilet drain device is known to exist that possesses structural and constitutive technical characteristics equal to or similar to those described in this specification, as claimed.

[0012] DESCRIPTION OF THE INVENTION

[0013] The object of the present invention is the creation of an improved toilet drain device, which brings a notable innovation within its field of application in the current state of the art, the characterizing details that make it possible being conveniently included in the final claims that accompany the present description.

[0014] The present invention relates to an improved toilet drain device, comprising a drain tube with a male threaded connection on its outer face, the inner face of which is glued into the main drain tube. This drain tube can be of different lengths to accommodate the various dimensions of existing toilet drains.

[0015] The device also comprises a flexible tube that has at one end a female threaded connection compatible with the male threaded connection, having at the other end of the flexible tube the same termination as a traditional toilet bowl sleeve, said termination being coupled to the outlet conduit of a toilet bowl.

[0016] This innovation solves the problems of leaks, bad smells and compatibility in toilet drainage systems by means of an airtight and adaptable seal, thanks to its threaded connection and watertight piece of various sizes.

[0017] This device is beneficial, especially for commercial and residential environments, such as homes, apartments, and multi-occupancy buildings, as it offers a durable solution that reduces long-term maintenance problems, avoiding frequent repairs and ensuring a more comfortable experience for users.

[0018] To install the improved toilet drain device, connect the male threaded fitting of the drain pipe to the female threaded fitting of the flexible hose. This will create a tight and secure seal around the toilet bowl, preventing any odors or leaks.

[0019] EXPLANATION OF THE FIGURES

[0020] To complete the description being made and in order to help in the better understanding of the characteristics of the invention, this descriptive report is accompanied, as an integral part thereof, by a figure in which, for illustrative and non-limiting purposes, the following has been represented.

[0021] Figure 1 shows a perspective view of the improved toilet drain device.

[0022] PREFERRED EMBODIMENT OF THE INVENTION.

[0023] The present improved toilet drain device is characterized by comprising

[0024] - a drain pipe (1) having a male threaded connection (2) on its outer face, and whose inner face is glued into the main drain pipe. This drain pipe may have different dimensions to accommodate the different dimensions of existing toilet drains. However, the dimension of the male threaded connection (2) will be such that it is compatible with the female threaded connection (3).

[0025] - a flexible tube (5) having at one end a female threaded connection (3) compatible with the male threaded connection (2), having at the other end of the flexible tube (5) the same termination as a traditional toilet bowl sleeve, said termination being coupled to the outlet conduit of a toilet bowl.

[0026] In one embodiment, the flexible tube (5) may have fixing means on its upper fins, for example clamps, to fix it to the wall or floor.

[0027] The drain pipe (1) is usually made from a lightweight, strong and durable material such as PVC plastic.

[0028] In a preferred embodiment, the watertight tube (4) has different dimensions, including at least 90 mm, 100 mm, and 110 mm, which ensures compatibility with different types of installations. Having sufficiently described the nature of the present invention, as well as how to implement it, it is not considered necessary to elaborate further so that any person skilled in the art can understand its scope and the advantages derived from it. It should be noted that, within its essential characteristics, it may be implemented in other embodiments that differ in detail from the one indicated by way of example, and these will also attain the protection sought, provided that its fundamental principle is not altered, changed, or modified.
