[0023] In order to make the above-mentioned purposes, features and advantages of the utility model more apparent, easy to understand, the specific embodiments of the utility model are described in detail below combined with the drawings of the specification.

[0025] Secondly, the "one embodiment" or "embodiment" referred to herein can include specific features, structures or characteristics in at least one implementation of the utility model. In this specification, "in one embodiment" does not mean the same embodiment, nor is it an independent or alternative embodiment that excludes other embodiments.

[0026] EMBODIMENT

[0027] REFERENCE Figures 1 to 5 For the embodiment of the utility model, the embodiment provides a high sealing water tank waterproof pad, which comprises a sealing gasket body 100 composed of a plurality of unit sealing gaskets 101;

[0028] The unit sealing gasket 101 is provided with a sealing strip assembly 102, and the sealing strip assembly 102 is provided with a groove 102c-1. The unit sealing gasket 101 is provided with an annular groove 101a, and extends into the sealing strip assembly 102. The annular grooves 101a between at least two adjacent unit sealing gaskets 101 are sealed.

[0029] Specifically, in this embodiment, the sealing gasket body 100 is spliced by at least two unit sealing gaskets 101, and each unit sealing gasket 101 is sealed by an annular groove 101a. Specifically, each unit sealing gasket 101 is provided with an annular groove 101a, and these annular grooves 101a not only seal each other but also extend to the inside of the sealing strip assembly 102. When the sealing gasket body 100 is sleeved on the corresponding position of the water tank body 200, the sealing strip assembly 102 on each unit sealing gasket 101 contacts the water tank body 200 to form a sealed area.

[0030] In each sealed area, the groove 102c-1 on the unit sealing gasket 101 forms a separation area, which together with the annular groove 101a forms an overall hollow area that separates adjacent unit sealing gaskets 101. The main purpose is to reduce the influence of heat transfer on the entire sealing gasket body 100, so that the aging of the sealing gasket body 100 mainly manifests as the aging of each unit sealing gasket 101 from the inside to the outside, which helps to prolong the overall service life of the sealing gasket body 100.

[0031] In addition, the hollow area formed by the separation area and the annular groove 101a also significantly improves the heat insulation performance of the sealing gasket body 100. Notably, under pressure, this hollow area can make the outer surface of the sealing strip assembly 102 tightly fit the assembly surface of the water tank body 200, thereby improving the sealing performance of the sealing gasket body 100. At the same time, when the sealing gasket body 100 expands due to temperature rise, more expansion volume will expand in the direction of the annular groove 101a, which not only increases the expansion volume of the sealing gasket body 100, further improving the sealing performance, but also effectively protects the overall structure of the sealing gasket body 100, avoiding problems such as mechanical stress, micro-crack formation, material performance degradation, interface separation, and dimensional change caused by thermal expansion and cold contraction, thereby delaying the aging process of the sealing ring, preventing loss of elasticity, rupture or leakage, and ultimately improving the sealing effect and service life.

[0032] For example, as shown in FIG. 1, the sealing gasket body 100 is spliced by two unit sealing gaskets 101, and each unit sealing gasket 101 is sealed by an annular groove 101a. Specifically, each unit sealing gasket 101 is provided with an annular groove 101a, and these annular grooves 101a not only seal each other but also extend to the inside of the sealing strip assembly 102. When the sealing gasket body 100 is sleeved on the corresponding position of the water tank body 200, the sealing strip assembly 102 on each unit sealing gasket 101 contacts the water tank body 200 to form a sealed area. Figures 1-5As shown, the sealing strip assembly 102 comprises a first sealing block 102a and a second sealing block 102b connected by a convex surface 102c, which forms a structure of two sealing strips in one unit sealing gasket 101, so that multiple unit sealing gaskets 101 have double sealing effect. Specifically, the first sealing block 102a cooperates with the water tank body 200 to form a first sealing area 100a, the second sealing block 102b cooperates with the water tank body 200 to form a second sealing area 100b, and the groove 102c-1 on the convex surface 102c cooperates with the water tank body 200 to form a separation area 100c. These functions can be realized on only one unit sealing gasket 101, so that the sealing and heat insulation of the sealing gasket body 100 composed of multiple unit sealing gaskets 101 are better than those of the conventional sealing gasket;

[0033] In this embodiment, as shown in Figure 3 、 Figure 4 、 Figure 5 As shown, the unit sealing gasket 101 is provided with an annular groove 101a, which extends into the first sealing block 102a and the second sealing block 102b to form a first recess 102a-1 and a second recess 102b-1, respectively. The annular groove 101a is in communication with the first recess 102a-1 and the second recess 102b-1.

[0034] In this embodiment, as shown in Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 As shown, the outer surface of the convex surface 102c is convex to the groove 102c-1 and is located between the first sealing block 102a and the second sealing block 102b. The convex surface 102c has good support for the first sealing block 102a and the second sealing block 102b, and is not easily compressed after the multiple unit sealing gaskets 101 are combined, and can better engage with the water tank body 200.
