[0017] The following describes the details and working principle of the implementation and examples of the utility model in conjunction with the accompanying drawings. The two ends of the water outlet pipe of the flush valve are respectively the water inlet end 2 and the water outlet end 4. The water inlet end and the water outlet end of the water outlet pipe are rigid straight pipes, and the middle section of the water outlet pipe is a corrugated pipe 3. The rigid straight pipe will not deform. The water inlet end 2 is connected to the water outlet of the flush valve, and the water outlet end 4 is provided with a sealing member 6, which is sealed with the water inlet of the toilet through the sealing member 6; the corrugated pipe 3 can be deformed. When the water outlet of the flush valve and the water inlet of the toilet are not in the same straight line, the water inlet end 2 and the water outlet end 4 of the water outlet pipe are misaligned by adjusting the corrugated pipe, so that the water outlet of the flush valve and the water inlet of the toilet are connected.
[0018] The water inlet end 2 is sleeved with a nut 1, the cap opening 9 of the nut matches the outer diameter of the water outlet pipe, the end of the water inlet end is provided with a limit ring 8 to prevent the positioning nut from being separated from the water outlet pipe, the outer diameter of the limit ring is larger than the outer diameter of the water outlet pipe, and the internal thread 7 of the nut matches the water outlet of the flush valve. During installation, the nut 1 is first inserted from the water outlet end 4, and the limit ring 8 of the water inlet end blocks the nut, and then the seal 6 is sleeved on the water outlet end, and the water outlet pipe is connected to the water outlet of the flush valve through the nut 1.
[0019] The seal 6 is a hollow structure, and the upper end 11 of the seal has a flange 16 extending outwardly, which can not only increase the strength but also increase the force-bearing area; the lower end 13 of the seal has a taper, and the outer diameter gradually increases, and the inner hole 10 of the seal is divided into a mounting section 14 that is tightly matched with the water outlet end of the water outlet pipe and a sealing section 15 with a taper, and the water outlet end of the water outlet pipe is in close contact with the mounting section 14 of the seal to achieve a sealing effect; the aperture of the sealing section 15 gradually increases and is trumpet-shaped. The taper of the lower end 13 of the seal is larger than the taper of the sealing section 15 of the inner hole of the seal, and the thickness of the lower end 13 of the seal gradually becomes thinner, so that the lower end of the seal is easier to deform and open, and the end face of the toilet water inlet is more tightly fitted. When the seal 6 is squeezed, the seal moves downward relative to the water outlet pipe, the lower end of the seal is stretched outward, and the internal air of the seal is discharged during the squeezing process to form a negative pressure. The adsorption force formed by the inner wall of the lower end 13 of the seal and the end face of the water inlet makes the two fit firmly, and the sealing effect is significant.
[0020] The main body 12 between the upper end 11 and the lower end 13 of the seal is cylindrical, and the outer diameter of the main body 12 is smaller than the outer diameters of the top and bottom ends of the seal. The upper end 11 and the main body 12 of the seal are thicker, have high strength, are not easily deformed, and play a supporting role. In addition, the upper end has a large outer diameter and a large pressure area, which is convenient for the user to press the seal downward during installation. The circumferential side of the seal is concave inward, which is conducive to the deformation of the lower end 13 of the seal. The seal is an integrated structure with good sealing and longer service life. The water outlet end of the water outlet pipe is also provided with a decorative cover 5, which is set outside the seal from above the seal. The decorative cover 5 not only increases the aesthetics, but also prevents the seal from being exposed, thereby extending the service life of the seal.
[0021] The utility model adopts a sealing member to directly cooperate with the water inlet of the toilet, thereby eliminating the need for a water outlet tail plug and reducing product costs. In addition, the sealing member is firmly adsorbed to the end face of the water inlet, resulting in a good sealing effect, and effectively preventing the water inlet of the toilet from leaking.
