[0020] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] like Figure 1-Figure 3As shown, a faucet inner tank includes a plastic part 10 and a metal part 20. One end of the metal part 20 is provided with at least one connecting column 21. Each connecting column 21 is provided with an internal thread section for connecting to a water inlet pipe or a water outlet pipe. The plastic part 10 has a connecting hole matching each connecting column 21. The outer diameter of the connecting column 21 matches the inner diameter of the connecting hole. In this embodiment, three connecting columns 21 are provided on the metal part 20, two of which are used to connect to the water inlet pipe, and one is used to connect to the water outlet pipe.

[0022] A push ring 22 for pushing against the plastic part 10 is integrally connected to one end of the metal part 20 away from the connecting column 21, and a connecting ring 23 is integrally connected to the outer wall of the metal part 20. A slot is formed between the push ring 22 and the connecting ring 23. At least two blocks are integrally connected to the plastic part 10, and each block is respectively snapped into the slot. In this embodiment, the block has a first connecting block 111 and a second connecting block 112. The second connecting block 112 is integrally connected to the first connecting block 111. The first connecting block 111 is integrally connected to the plastic part 10. The thickness of the second connecting block 112 gradually decreases from the end close to the first connecting block 111 to the end away from the first connecting block 111, and the longitudinal section of the second connecting block 112 is a right triangle. The thickness of the second connecting block 112 gradually decreases to increase the elastic force of the second connecting block 112, so as to facilitate the snapping of the block into the slot and facilitate the connection between the metal part 20 and the plastic part 10.

[0023] A conventional sealing ring (not shown in the figure) is sleeved on the connecting column 21, a first abutting top platform 12 is formed on the inner wall of the plastic component 10, and a first abutting top portion 24 is provided on the outer wall of the metal component 20. One end of the sealing ring abuts against the first abutting top portion 24, and the other end of the sealing ring abuts against the first abutting top platform 12. By providing the first abutting top platform 12, the sealing ring and the first abutting top portion 24, the plastic component 10 and the metal component 20 are sealed to prevent water leakage from the faucet tank.

[0024] As a preferred embodiment of the present invention, a sealing ring 25 is provided on one end of each connecting column 21 away from the abutting ring 22, a sealing hole matching the sealing ring 25 is provided in the plastic part 10, and the connecting hole is communicated with the sealing hole. In the present embodiment, the outer diameter of the sealing ring 25 matches the inner diameter of the sealing hole, and the sealing between the metal part 20 and the plastic part 10 is further enhanced by arranging the sealing ring 25 in coordination with the sealing hole.

[0025] As a preferred mode of the present embodiment, a second abutment top platform 13 is provided in the plastic component 10, and a second abutment top platform 26 is provided on the outer wall of the metal component 20 corresponding to between the connecting ring 23 and the first abutment top platform 24, and the second abutment top platform 26 abuts against the second abutment top platform 13, so as to further enhance the sealing performance of the faucet inner tank.

[0026] In summary, the metal component 20 and the plastic component 10 are connected together by setting the block and the slot. Under the action of water pressure, the block on the plastic component 10 is tightly buckled in the slot, which can effectively prevent the faucet tank from leaking.

[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
