[0023] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention will be further described below with reference to the accompanying drawings.

[0024] Please refer to Figure 2 and Figure 5 As shown, the embodiment of the present invention provides a water purifier pressure barrel inner liner sealing assembly, including a pressure barrel body 18, an inner liner body 19 is installed inside the pressure barrel body 18, a sealing cover 6 is provided on the top of the pressure barrel body 18 and matched with the pressure barrel body 18, a reset telescopic rod 20 is provided at the center of the sealing cover 6, a disassembly assembly is provided inside the sealing cover 6, and a sealing assembly is provided at the bottom of the disassembly assembly;

[0025] The disassembly assembly includes a connecting groove 2 and an installation groove 3 opened inside the sealing cover 6. A telescopic rod 5 is installed inside the installation groove 3. The external fixed sleeve of the telescopic rod 5 is provided with a limit plate 7. The limit plate 7 is slidably connected to the installation groove 3. The external sleeve of the telescopic rod 5 is provided with a return spring 4. The telescopic rod 5 is fixedly connected to a tightening block 1 on the side close to the connecting groove 2.

[0026] Please refer to Figure 4 As shown, the sealing assembly includes a plug-in block 13 inserted into the connecting groove 2, a mounting ring 12 is installed at the bottom of the plug-in block 13, a sealing ring 11 is installed at the bottom of the mounting ring 12, a limiting block 15 is installed on the inner side of the sealing ring 11, and the end of the limiting block 15 is connected to the sealing ring 2 16. The limiting block 15 on the inner side of the sealing ring 11 slides inside the limiting groove 10 until it slides to the side away from the guide groove 9. At this time, the reaction force of the resetting telescopic rod 20 cooperates with the limiting groove 10 through the limiting block 15, thereby fixing the sealing ring 11 and the sealing groove 8.

[0027] Please refer to Figure 4As shown, a sealing groove 8 is formed at the top of the pressure barrel body 18, and a guide groove 9 and a stop groove 10 are formed inside the sealing groove 8. Rotating the sealing cover 6 counterclockwise separates the sealing ring 11 at the bottom of the sealing cover 6 from the sealing groove 8. Rotating the sealing cover 6 clockwise secures the sealing ring 11 to the sealing groove 8.

[0028] Please refer to Figure 4 As shown, the sealing ring 11 is fitted with the sealing groove 8, and the limit blocks 15 are fitted with the guide groove 9 and the limit groove 10. The sealing cover 6 is rotated clockwise so that the limit block 15 on the inner side of the sealing ring 11 slides inside the limit groove 10 until it slides to the side away from the guide groove 9. At this time, the reaction force of the resetting telescopic rod 20 cooperates with the limit groove 10 through the limit block 15, thereby fixing the sealing ring 11 and the sealing groove 8.

[0029] Please refer to Figure 4 and Figure 5 As shown, a plug-in groove 14 is provided inside the plug-in block 13, and the plug-in groove 14 fits with the tightening block 1. By pulling the sealing ring 11, the mounting ring 12 on the top of the sealing ring 11 is separated from the tightening block 1 through the plug-in groove 14 inside the guide groove 9. At the same time, when replacing, it is only necessary to plug the plug-in block 13 on the mounting ring 12 on the top of the sealing ring 11 into the inside of the connecting groove 2 to complete the disassembly and installation.

[0030] Please refer to Figure 1 and Figure 3 As shown, a sealing ring 3 17 is installed at the bottom of the sealing cover 6, and the sealing ring 3 17 contacts the outside of the pressure barrel body 18. The sealing ring 3 17 at the bottom of the sealing cover 6 contacts the outside of the pressure barrel body 18, thereby increasing the sealing effect between the sealing cover 6 and the pressure barrel body 18.

[0031] Working principle:

[0032] When the inner liner body 19 is installed in the pressure barrel body 18, the sealing ring 11 at the bottom of the sealing cover 6 is fitted and fixed with the sealing groove 8 opened at the top of the installation groove 3. During this process, the reset telescopic rod 20 at the center of the sealing cover 6 will limit the inner liner body 19 installed inside the pressure barrel body 18. At this time, the limit block 15 contacts the guide groove 9, and then the sealing cover 6 is rotated clockwise, so that the limit block 15 on the inner side of the sealing ring 11 slides inside the limit groove 10 until it slides to the side away from the guide groove 9. At this time, the reaction force of the reset telescopic rod 20 cooperates with the limit groove 10 through the limit block 15, and then fixes the sealing ring 11 to the sealing groove 8. At this time, the sealing ring 2 16 fixes the inner side of the pressure barrel body 18, and at the same time, the sealing ring 3 17 outside the sealing cover 6 fixes the outer side of the pressure barrel body 18, thereby increasing the external sealing effect and avoiding gaps at the end of the pressure barrel body 18, which affects the pressure barrel body. The inner liner body 19 of the body 18 is used. When the sealing ring 11 needs to be replaced, the sealing cover 6 is rotated counterclockwise so that the sealing ring 11 at the bottom of the sealing cover 6 drives the limiting block 15 to slide inside the limiting groove 10 to the side close to the guide groove 9, and then the sealing cover 6 is pulled, thereby separating the sealing ring 11 at the bottom of the sealing cover 6 from the sealing groove 8, and then the sealing ring 11 is pulled, so that the mounting ring 12 at the top of the sealing ring 11 is separated from the tight block 1 through the plug-in groove 14 inside the guide groove 9. During the separation process, the tight block 1 drives the return spring 4 outside the telescopic rod 5 to be squeezed and contracted, thereby separating the tight block 1 from the plug-in groove 14. When replacing, it is only necessary to insert the plug-in block 13 on the mounting ring 12 at the top of the sealing ring 11 into the inside of the connecting groove 2, so that the plug-in groove 14 is fixed by the tight block 1 under the action of the telescopic rod 5 and the return spring 4, thereby facilitating the replacement of the sealing ring 11.

[0033] Of course, the present invention may have many other implementations. Based on this implementation, other implementations obtained by ordinary technicians in this field without any creative work are all within the scope of protection of the present invention.
