[0027] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the utility model for which protection is claimed, but merely represents selected embodiments of the utility model.

[0028] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0029] Reference Figures 1 to 7As shown, a water seal assembly includes a pipe body 1 and a movable cover 2. The pipe body 1 includes a straight tube section 11 and a tapered section 12 from top to bottom. The peripheral projection surface of the tapered section 12 at each position is smaller than the peripheral projection surface of the straight tube section 11. The pipe body 1 is formed with a water flow channel 131. The upper end of the movable cover 2 is rotatably buried in the interior of the pipe body 1, and the lower end of the movable cover 2 can be switched between the positions of opening or closing the water flow channel 131. Therefore, when the pipe body 1 is inserted into the pipeline, even if the pipe body 1 is tilted, it will not affect the opening and closing of the movable cover 2, which can prevent the problem of interference between the movable cover 2 and the pipeline after the pipe body 1 is installed crookedly, and the pipe body 1 can be inserted into the pipeline at any angle and the opening or closing of the movable cover 2 can be guaranteed.

[0030] In one embodiment, the straight section 11 is a cylindrical structure, and the necking section 12 is an arc-shaped necking structure with a diameter gradually decreasing from top to bottom, so that the lower end of the necking section 12 has a minimum diameter, and the diameter of the straight section 11 differs from the minimum diameter by more than 3 mm. In this embodiment, the movable cover 2 attached to the bottom of the necking section 12 will not interfere with the pipeline during the opening or closing process, and the product as a whole is more beautiful.

[0031] In another embodiment, the necking section 12 is surrounded by a plurality of inclined surfaces 121 that are arranged inwardly and tilted from top to bottom.

[0032] The outer diameter of the movable cover 2 is smaller than or equal to the outer diameter of the bottom of the necked section 12, thereby further preventing the movable cover 2 from interfering with the pipeline during the opening or closing process.

[0033] The inner wall of the tube body 1 is provided with a diverting protrusion 132. When the water flows into the tube body 1, it will adhere to the inner wall of the tube body 1, and then the water will impact the diverting protrusion 132, so that gaps and bubbles are generated between the water flow and the inner wall of the tube body 1, thereby accelerating the speed at which the water flows out of the tube body 1, thereby accelerating the discharge of the water. Specifically, the diverting protrusion 132 is an inverted V-shaped protrusion structure, which can reduce the noise of the water flow when it is diverted.

[0034] The tube body 1 includes a first side shell 13 and a second side shell 14, and the second side shell 14 is detachably fixed to the first side shell 13. Specifically, the outer side elevation 133 of the first side shell 13 is formed with two first protrusions 1331, and the outer top plane 134 of the first side shell 13 is formed with two first grooves 1341, and the outer side elevation 133 and the outer top plane 134 are vertically distributed, and the second side shell 14 is provided with a first positioning portion 141 clamped with the first protrusion 1331, and a second positioning portion 142 clamped with the first groove 1341, so that the first side shell 13 and the second side shell 14 are detachably fixed together.

[0035] The first side shell 13 is formed with the above-mentioned water flow channel 131, the outer facade 133 of the first side shell 13 is provided with a hook portion 1332, the movable cover 2 is provided with a rotating shaft 24 hung on the hook portion 1332, and the second side shell 14 is provided with a pressing portion 143 covering the upper part of the rotating shaft 24. The rotating shaft 24 is limited by a circular rotating hole surrounded by the hook portion 1332 and the pressing portion 143, so that the movable cover 2 is stably rotatably connected to the tube body 1 through the rotating shaft 24.

[0036] The movable cover 2 is embedded with a first magnet 22, and the first side shell 13 is embedded with a second magnet 136. The movable cover 2 maintains a closed water flow channel 131 through the mutual adsorption of the first magnet 22 and the second magnet 136, so that the water flow channel 131 can be opened only when the water flow impacts the movable cover 2. Under normal circumstances, the water flow channel 131 is in a closed state, thereby playing an insect-proof and odor-proof role for the pipeline. The first magnet 22 and the second magnet 136 can quickly reset the movable cover 2 after opening.

[0037] The movable cover 2 is provided with a first mounting groove 21, and the first mounting groove 21 is arranged behind the rotating shaft 24. The first magnet 22 is embedded in the first mounting groove 21. The side wall of the first mounting groove 21 is provided with a plurality of first clamping strips 211 whose protrusion height gradually increases along the depth direction; when the first magnet 22 is installed into the first mounting groove 21, the first clamping strips 211 act to make the first magnet 22 gradually interference fit with the first mounting groove 21, thereby preventing the first magnet 22 from being separated from the first mounting groove 21 due to external force shaking the water seal assembly.

[0038] Similarly, the first side shell 13 is provided with a second mounting groove 135 , and the second magnet 136 is embedded in the second mounting groove 135 . The side wall of the second mounting groove 135 is provided with a plurality of second clamping strips 1351 with gradually increasing protrusion heights along the depth direction.

[0039] A pull ring 3 is provided on the inner circumference of the tube body 1. The pull ring 3 can be rotated to a position lower than the top surface of the tube body 1. The pull ring 3 is rotatably connected to the tube body 1. The water seal assembly can be easily detached from the pipeline by pulling the pull ring 3. When it is in the storage position, the pull ring 3 is lower than the top surface of the tube body 1. Compared with the traditional pull ring 3 protruding from the top surface of the tube body 1, the position of the pull ring 3 below the top surface of the tube body 1 can enable the water flow on the ground to smoothly enter the tube body 1 and be discharged, thereby preventing the pull ring 3 from blocking the discharge of water flow.

[0040] The movable cover 2 is provided with an elastic ring 23, which is preferably made of silicone material. The elastic ring 23 abuts against the circumference of the lower end of the tube body 1, so that the movable cover 2 can more tightly close the water flow channel 131 and improve the anti-odor performance of the water seal assembly.

[0041] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
