[0007] A waterproof structure for a water purifier interface includes an installation port on the outer casing of the water purifier main unit for the interface of the water supply board to protrude, a conformal seal disposed in the installation port, and a pressure plate disposed on the conformal seal. Both the conformal seal and the pressure plate have through holes for the interface to pass through. The upper end of the conformal seal is provided with an outer edge extending away from the installation port. The pressure plate is used to press the outer edge tightly against the outer casing.
[0008] Preferably, at least two sealing rings are provided inside the through hole.
[0009] Preferably, the upper end of the conformal seal is provided with a groove, and the pressure plate is provided with a pressure groove corresponding to the groove.
[0010] Preferably, a sealing strip is provided on the inner wall of the groove.

[0013] Preferably, a support plate is provided around the interface on the water circuit board, and the support plate is provided with screw hole posts corresponding to the through holes, and the screw hole posts are connected with the bolts.
[0014] Preferably, the support plate and the water channel plate are integrally formed.
[0015] Preferably, at least two screw holes are provided, and they are arranged on both sides of the interface.
[0016] Preferably, the size of the support plate is not less than the projected area of the contour seal on the plane of the support plate.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] This utility model provides a waterproof structure for a water purifier interface, achieving a sealed waterproof seal between the interface and the outer shell, thereby preventing water from flowing into the interior of the outer shell through the gap between the interface and the outer shell.
[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0027] refer to Figures 1 to 2 A waterproof structure for a water purifier interface includes an installation port 14 on the outer casing 9 of the water purifier main unit, through which the interface 7 of the water supply circuit board 11 protrudes; a contoured sealing member 2 disposed within the installation port 14; and a pressure plate 1 disposed on the contoured sealing member 2. Both the contoured sealing member 2 and the pressure plate 1 have through holes 3 for the interface 7 to pass through. The upper end of the contoured sealing member 2 has an outer edge 13 extending away from the installation port 14. The pressure plate 1 is used to press the outer edge 13 tightly against the outer casing. 9. The present invention provides an installation opening 14 on the outer shell 9 to expose the interface 7 of the water circuit board. A contoured sealing element 2 and a pressure plate 1 are provided in the opening. The contoured sealing element 2 has through holes 3 for each interface 7 to pass through. The upper part of the contoured sealing element 2 has an outer edge. The pressure plate 1 presses the outer edge of the contoured sealing element 2 tightly onto the opening of the outer shell 9. The interface 7 is tightly wrapped by the through holes 3 of the contoured sealing element 2, thereby achieving a waterproof seal between the interface 7 and the outer shell 9 and preventing water from flowing into the interior of the outer shell 9 from the gap between the interface 7 and the outer shell 9.
[0028] refer to Figure 3 At least two sealing rings 12 are provided inside the through hole. The sealing rings 12 are set on the inner wall of the through hole 3 and are evenly arranged at intervals along the depth of the through hole 3, thereby achieving multiple seals between the interface and the conformal seal 2, ensuring the sealing effect, and preventing water from flowing into the water purifier from the gap between the conformal seal 2 and the interface.
[0029] refer to Figure 2 The contour seal 2 and the pressure plate 1 are both elliptical plate structures. The groove of the contour seal 2 is a groove 5 formed by the recess of the plate structure, and the pressure plate 1 is also a groove formed by the recess of its own plate structure. The groove matches the groove 5, and the groove can be pressed into the groove 5 and seamlessly pressed together.
[0030] Furthermore, a sealing strip is provided on the inner wall of the groove 5.
[0031] refer to Figure 1 The inner wall of the mounting port 14 is provided with a stepped mounting groove 6. The outer edge overlaps the mounting groove 6 and the upper surface of the outer edge is flush with the surface of the outer shell 9. On the one hand, the extension of the outer edge 13 is used to ensure the sealing effect between the conformal seal 2 and the outer shell 9. On the other hand, the outer edge 13 is flush with the surface of the outer shell 9 and will not protrude from the surface of the outer shell 9, thus ensuring the aesthetics of the entire water purifier interface waterproof structure.
[0032] refer to Figure 2 Both the contour seal 2 and the pressure plate 1 are provided with corresponding through holes 4, and the contour seal 2 is fixed to the water circuit plate 11 by bolts passing through the through holes 4; the purpose is that the bolts can pass through the pressure plate 1 and the contour seal 2 to lock and fix the contour seal 2 to the water circuit plate 11.
[0033] refer to Figure 2 A support plate 8 is provided around the interface 7 on the water circuit plate 11. The support plate 8 is provided with screw hole posts 10 corresponding to the through hole 4. The screw hole posts 10 are connected with the bolts. The contour seal 2 can be pressed between the support plate 8 and the pressure plate 1 to ensure the sealing effect of the contour seal 2.
[0034] refer to Figure 2 The support plate 8 and the water channel plate 11 are integrated.
[0035] refer to Figure 2 Six screw holes 10 are provided, and three are arranged on the support plates 8 on both sides of the interface 7. The purpose is to ensure the uniformity and stability of the connection between the contour seal 2, the pressure plate 1 and the support plate 8.
[0036] Furthermore, the size of the support plate 8 is not less than the projected area of the contour seal 2 on the plane where the support plate 8 is located; as the main structure on the weight side of the contour seal 2 and the pressure plate 1, the large bearing area of the support plate 8 is conducive to ensuring the stability of the contour seal 2 and the pressure plate 1 during the installation process.
[0037] It should be noted that, for those skilled in the art, it is obvious that this utility model is not limited to the details of the above exemplary embodiments, and that this utility model can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered as exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description. Therefore, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.
