Description

Technical fields:

[0001] This utility model relates to the field of bathroom technology, specifically a pull-out drain that can be cleaned quickly. Background technology:

[0002] During daily use, drains are prone to getting tangled with hair, causing blockages. Current drains are not very effective at collecting and cleaning hair. Most drains use built-in filters to collect hair, but because the filters are inside the drain, users cannot accurately see the internal condition and often cannot clean them in time. This leads to slower drainage and unpleasant odors. Utility model content:

[0003] The technical problem to be solved by this utility model is to provide a pull-up drain that can be cleaned quickly, which changes the original collection and passive cleaning mode to a collection and active cleaning mode, and can effectively avoid the defects of dirt and grime accumulation caused by long-term neglect of the built-in filter.

[0004] The technical solution of this utility model is to provide a pull-up drain that can be cleaned quickly, characterized by comprising a main body, a flange, a water plug, a water-stop ring, a ball rod, and an adjusting plate assembly; wherein,

[0005] The flange is installed above the drain outlet of the basin. It is a normally open flange, and the top surface of the flange is provided with multiple drain holes.

[0006] The main body is installed at the lower part of the basin drain outlet, and its upper part is fixed to the flange by threaded connection. The main body is provided with a side opening.

[0007] The water plug body and the water stop ring are disposed in the cavity formed by the flange and the body, and the water stop ring is fitted onto the upper part of the water plug body;

[0008] The front end of the cue stick is movably connected to the bottom of the water plug body, and the rear end of the cue stick extends out of the side opening of the main body;

[0009] The adjusting plate assembly is connected to the rear end of the ball rod. By lifting or pressing the adjusting plate assembly, the ball rod and the water plug connected to it move up and down in the cavity, so that the water-stop ring is in contact with or separates from the inner wall of the flange, thereby realizing the sealing of the drain or the opening of the drain.

[0010] Preferably, the water plug body is a one-piece structure with an annular groove on its upper part for accommodating the water-stop ring, the water-stop ring being fitted into the annular groove, and a bottom hole penetrating the bottom center of the water plug body, the front end of the ball rod passing through the bottom hole and being movably connected to the water plug body.

[0011] Preferably, the device also includes a nut, a mortise pad, and a shim, which are sequentially fitted onto the main body from top to bottom to achieve sealing and fixation with the basin drain outlet.

[0012] Preferably, a side opening gasket is also installed inside the side opening.

[0013] Preferably, the front end of the cue stick passes through the bottom hole and is fitted with a side nut, and is locked in place by a threaded connection.

[0014] Preferably, the adjustment plate assembly is provided with multiple adjustment holes for adjusting the height, and is engaged with the ball rod by a spring plate to determine and maintain the installation height and lateral position of the drainer.

[0015] Preferably, in the closed state, pulling up the adjusting plate assembly causes the water plug to descend, and the water stop ring fits tightly against the inner wall of the flange to achieve a seal; in the open state, pressing down the adjusting plate assembly causes the water plug to rise, and the water stop ring is located in the large inner hole of the flange, and water flows through the drain hole of the flange and the gap between the water stop ring and the inner wall of the flange.

[0016] Compared with the prior art, the present invention has the following advantages after adopting the above solution:

[0017] This utility model combines the advantages of both normally open and pull-out drainers. It can collect hair and debris on the flange surface, allowing users to detect and handle them promptly, reducing subsequent blockages and odors. Furthermore, by combining the opening and closing mechanism of the pull-out type, it overcomes the disadvantage of normally open drainers being unable to seal water. By taking the best of both worlds, it achieves a more efficient and innovative drainer combination. Attached image description:

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0024] like Figure 1-3 As shown, a quick-cleaning pull-up drain consists of 12 parts: flange 1, water-stop ring 2, water plug body 3, gasket 4, friction pad 5, nut 6, main body 7, side gasket 8, ball rod 9, side nut 10, spring plate 11, and adjusting plate assembly 12.

[0025] In this embodiment, flange 1 is a normally open flange with 45 φ4mm drainage holes on its flat surface to ensure its flow rate. The overall installation sequence is as follows: the nut 6, friction pad 5, and differential pad 4 are sequentially fitted onto the main body 7 from top to bottom. The water plug 3 is a one-piece molded structure with an annular groove at its upper part for accommodating the water-stop ring 2. The water-stop ring 2 is fitted into the annular groove and then inserted into the inner hole of the main body 7, so that the front of the water plug 3 faces the side opening of the main body 7. A bottom hole 13 penetrating the bottom is provided at the center of the bottom of the water plug 3. Then, the side gasket 8 and the ball rod 9 are inserted sequentially from the side opening, with the front end of the ball rod 9 passing through the bottom hole 13 of the water plug 3. The side nut 10 is then fitted on and tightened by threads. The assembled whole is then fitted into the basin from bottom to top, and flange 1 is inserted from top to bottom. Flange 1 and main body 7 are connected and tightened by threads. The adjusting plate assembly 12 has multiple adjusting holes for height adjustment and is engaged with the ball rod 9 by a spring plate 11. Finally, the adjusting plate assembly 12 and spring plate 11 are fitted onto the ball rod 9 according to the position of the basin. The height is determined by adjusting the adjusting holes on the adjusting plate assembly 12, and the lateral position is determined by the spring plate 11. Since the flange 1 adopts a normally open flange structure, drainage cannot be controlled by pressing or flipping. Furthermore, normally open drainage cannot meet the needs of watertightness in daily life. Therefore, a combination of normally open and pull-out design is used to satisfy both drainage requirements and convenient cleaning.

[0026] Its working method is as follows Figure 4 As shown, pulling up the adjusting plate assembly 12 causes the ball rod 9 and the water plug 3 to descend. At this time, the water-stop ring 2 is in contact with the inner wall of the flange 1, achieving a closed and watertight effect. Pressing down the adjusting plate assembly 12 causes the ball rod 9 to rise, and the water-stop ring 2 is now in the large inner hole of the flange 1. Water flows out through the gap between the inner wall of the flange 1 and the water-stop ring 2, achieving the effect of a drain. Its open and closed state appears unchanged, and contact during daily use will not affect its watertight effect.

[0027] The above description only illustrates preferred embodiments of the present invention and should not be construed as limiting the scope of the claims. Any equivalent structural or procedural modifications made using this specification are included within the patent protection scope of this invention.
