The inner flange includes an inner ring 1 and an output cylinder 2, the output cylinder 2 is fixedly arranged on the end surface of the inner ring 1, and the limiting ring 3 is sleeved and matched with the output cylinder 2; the inner ring 1 is used to abut against the inner wall of the water tank during installation, the limiting ring 3 is installed on the outer wall of the water tank flange, the output cylinder 2 passes through the installation hole of the water tank, and the limiting ring 3 is sleeved on the output cylinder 2.

[0033] In this embodiment, the inner ring 1 and the output cylinder 2 are integrally formed, so that the overall structure can be more solid.

[0034] In this embodiment, the limiting ring 3 and the inner ring 1 are respectively arranged on the outer wall and the inner wall of the water tank, and the limiting ring 3 and the inner ring 1 are connected by connecting bolts 4. In this embodiment, six connecting bolts 4 are arranged, and the connecting bolts 4 are separate, freely movable parts. An inner through hole 11 is arranged on the inner ring 1, and a plurality of through connecting holes 31 cooperating with the inner through hole 11 are arranged in the circumferential direction of the limiting ring 3. During installation, the connecting bolt 4 passes through the inner through hole 11, then passes through the side wall of the water tank, and then passes through the through connecting holes 31 and is connected with the nut 41, so that the inner ring 1 and the limiting ring 3 are installed on the water tank, so that the inner ring 1 and the limiting ring 3 are respectively located on the inner wall and the outer wall of the water tank, and the output cylinder 2 is penetrated through the side wall of the water tank, so that the liquid in the water tank flows out from the output cylinder 2.

[0035] The difference between the present embodiment and the prior art is that the output cylinder 2 and the inner ring 1 in the present embodiment are integrally formed, which makes it not only more convenient to install, but also simpler in structural parts. Secondly, water can flow out directly from the output cylinder 2, without having to pass through the left flange, the special-shaped rubber gasket, the water tank template block, the special-shaped rubber gasket and the right flange in sequence as described in the above background technology, so the present application reduces the possibility of leakage. Therefore, the present application has the characteristics of easy installation and good sealing effect.

[0036] Example 2: Reference Figures 4 to 6 As shown, a water tank flange assembly includes: an inner flange and a limiting ring 3. The inner flange includes an inner ring 1 and an output cylinder 2, the output cylinder 2 is fixedly arranged on the end surface of the inner ring 1, and the limiting ring 3 is sleeved and matched with the output cylinder 2; the inner ring 1 is used to abut against the inner wall of the water tank during installation, the limiting ring 3 is installed on the outer wall of the water tank flange, the output cylinder 2 passes through the installation hole of the water tank, and the limiting ring 3 is sleeved on the output cylinder 2.

[0037] In this embodiment, the inner ring 1 and the output cylinder 2 are integrally formed, so that the overall structure can be more solid.

[0038] The difference between the structures of this embodiment and the embodiment 1 is that a plurality of connecting bolts 4 are evenly distributed along the circumferential direction on the end surface of the inner ring 1 close to the output cylinder 2. In this embodiment, six connecting bolts 4 are provided, and a plurality of through connecting holes 31 cooperating with the connecting bolts 4 are provided in the circumferential direction of the limiting ring 3. One end of the connecting bolt 4 in the present application is fixedly arranged inside the inner ring 1.

[0039] During installation, the connecting bolt 4 passes through the side wall of the water tank, and then passes through the through connecting hole 31 to connect with the nut 41, so that the inner ring 1 and the limiting ring 3 are installed on the water tank, so that the inner ring 1 and the limiting ring 3 are respectively located on the inner wall of the water tank and the outer wall of the water tank, and the output cylinder 2 passes through the side wall of the water tank, so that the liquid in the water tank flows out from the output cylinder 2.

[0040] In this embodiment, since the end of the connecting bolt 4 is arranged inside the inner ring 1, the connecting bolt 4 will not be exposed to the water in the water tank, which can prevent the connecting bolt 4 from contacting the liquid in the water tank, thereby preventing the liquid in the water tank from being polluted by the rust of the connecting bolt 4, thereby preventing the water quality from being polluted and making it healthier to use. In addition, the connecting bolt 4 in the prior art is prone to rust when in contact with the liquid, which makes the thread of the connecting bolt 4 easily damaged, making it difficult to remove the connecting bolt 4 when the flange needs to be replaced. At the same time, since the connecting bolt 4 does not contact the liquid in the water tank, the problem of rusting of the connecting bolt 4 can be effectively prevented, and the problem of difficulty in replacing the water tank flange assembly due to rust of the connecting bolt 4 is also avoided.

[0041] In addition, the output cylinder 2 and the inner ring 1 in this embodiment are integrally formed, which makes it not only more convenient to install, but also simpler in structural parts. Secondly, water can flow out directly from the output cylinder 2, without having to pass through the left flange, the special-shaped rubber gasket, the water tank template block, the special-shaped rubber gasket and the right flange in sequence as described in the above background technology, so that the present application reduces the possibility of leakage. Therefore, the present application has the characteristics of easy installation and good sealing effect.

[0042] Example 3: Reference Figures 4 to 6 As shown, a water tank flange assembly includes: an inner flange and a limiting ring 3. The inner flange includes an inner ring 1 and an output cylinder 2, the output cylinder 2 is fixedly arranged on the end surface of the inner ring 1, and the limiting ring 3 is sleeved and matched with the output cylinder 2; the inner ring 1 is used to abut against the inner wall of the water tank during installation, the limiting ring 3 is installed on the outer wall of the water tank flange, the output cylinder 2 passes through the installation hole of the water tank, and the limiting ring 3 is sleeved on the output cylinder 2.

[0043] In this embodiment, the inner ring 1 and the output cylinder 2 are integrally formed, so that the overall structure can be more solid.

[0044] The difference between the structures of this embodiment and the embodiment 1 is that a plurality of connecting bolts 4 are evenly distributed along the circumferential direction on the end surface of the inner ring 1 close to the output cylinder 2. In this embodiment, six connecting bolts 4 are provided, and a plurality of through connecting holes 31 cooperating with the connecting bolts 4 are provided in the circumferential direction of the limiting ring 3. One end of the connecting bolt 4 in the present application is fixedly arranged inside the inner ring 1.

[0045] In order to improve the sealing effect, the present embodiment also includes a sealing ring 5, which is sleeved on the output cylinder 2; when in use, the sealing ring 5 abuts between the inner side wall of the water tank and the inner ring 1, thereby effectively playing an effective sealing effect between the inner ring 1 and the inner side wall of the water tank, further improving the sealing performance. For the convenience of installation, a number of sealing perforations 54 for passing the connecting bolts 4 are provided on the sealing ring 5. Unlike the prior art, the present embodiment does not require the sealing ring 5 to be provided on both the inner side wall and the outer side wall of the box body, but only requires the sealing ring 5 to be provided on one side of the inner side wall of the water tank, and a good sealing effect can be achieved. This is because, since the inner ring 1 and the output cylinder 2 in the present application are integrally formed, as long as the liquid in the water tank does not leak out from the outer side wall of the output cylinder 2, there is no possibility of leakage. Therefore, the present application only requires the sealing ring 5 to be provided on the inner side wall of the water tank to achieve a good sealing effect.

[0046] During installation, the connecting bolt 4 passes through the side wall of the water tank, passes through the sealing ring 5 from the sealing through hole 54, and then passes through the through connecting hole 31 to connect with the nut 41, so that the inner ring 1 and the limiting ring 3 are installed on the water tank, so that the inner ring 1 and the limiting ring 3 are respectively located on the inner wall of the water tank and the outer wall of the water tank, and the output cylinder 2 is penetrated through the side wall of the water tank, so that the liquid in the water tank flows out from the output cylinder 2.

[0047] In this embodiment, since the end of the connecting bolt 4 is arranged inside the inner ring 1, the connecting bolt 4 will not be exposed to the water in the water tank, which can prevent the connecting bolt 4 from contacting the liquid in the water tank, thereby preventing the liquid in the water tank from being polluted by the rust of the connecting bolt 4, thereby preventing the water quality from being polluted and making it healthier to use. In addition, the connecting bolt 4 in the prior art is prone to rust when in contact with the liquid, which makes the thread of the connecting bolt 4 easily damaged, making it difficult to remove the connecting bolt 4 when the flange needs to be replaced. At the same time, since the connecting bolt 4 does not contact the liquid in the water tank, the problem of rusting of the connecting bolt 4 can be effectively prevented, and the problem of difficulty in replacing the water tank flange assembly due to rust of the connecting bolt 4 is also avoided.

[0048] In addition, the output cylinder 2 and the inner ring 1 in this embodiment are integrally formed, which makes it not only more convenient to install, but also simpler in structural parts. Secondly, water can flow out directly from the output cylinder 2, without having to pass through the left flange, the special-shaped rubber gasket, the water tank template block, the special-shaped rubber gasket and the right flange in sequence as described in the above background technology, so that the present application reduces the possibility of leakage. Therefore, the present application has the characteristics of easy installation and good sealing effect.

[0049] Embodiment 4: This embodiment is similar in structure to Embodiment 3, except that, in order to further improve the sealing effect, a plurality of sealing convex rings 51 are provided on both side end faces of the sealing ring 5. The plurality of sealing convex rings 51 on each side end face of the sealing ring 5 are concentrically arranged, thereby further improving the sealing effect.

[0050] In addition, the plurality of sealing protrusions 51 on the end surface of each sealing ring 5 divide the plurality of sealing protrusions 51 into an inner sealing ring group 52 and an outer sealing ring group 53; the inner sealing ring group 52 is arranged in the inner radial direction of the sealing ring 5, and the outer sealing ring group 53 is arranged in the outer radial direction of the sealing ring 5. The inner sealing ring group 52 and the outer sealing ring group 53 each include at least three sealing protrusions 51.

[0051] The inner sealing ring group 52 and the outer sealing ring group 53 can form a good sealing structure near the inner edge of the sealing ring 5 and the outer edge of the sealing ring 5 respectively, thereby effectively improving the sealing effect of the sealing ring 5 and more effectively preventing the water in the water tank from leaking out.

[0052] Embodiment 5: This embodiment is similar in structure to Embodiment 1, Embodiment 2, Embodiment 3, and Embodiment 4, except that in this embodiment, a rounded corner is provided at one end of the through-connection hole 31 close to the inner disc, so that the diameter of the through-connection hole 31 gradually increases toward the inner disc. The above structure gradually increases the opening of the through-connection hole 31, so that the connecting bolt 4 can be installed more conveniently, thereby improving the assembly efficiency of the present application.
