[0025] ​​​​To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0028] Example

[0029] Reference Figures 1 to 6 This is an embodiment of the present invention, which provides an siphon pad for improving sealing performance, including a siphon pad 100;

[0030] The outer surface 101 of the siphon pad 100 is recessed into its inner cavity, the upper lip 103 is located at the top of the outer surface 101, and the lower lip 104 is located at the bottom of the outer surface 101.

[0031] The inner surface 102 of the siphon pad 100 has at least two recesses 102a, the bottom of which extends close to the lower lip 104.

[0032] like Figure 1 , Figure 6 Specifically, the installation method of the siphon pad 100 is similar to that of a traditional siphon pad, that is, the siphon pad 100 is installed inside the housing 300, the upper lip 103 is sealed to the inner wall of the housing 300, and the lower lip 104 is fitted onto the outer surface of the inner shell 200 inserted into the housing 300. The through hole 300b on the outer surface of the housing 300 is completely blocked after the siphon pad 100 expands.

[0033] Unlike traditional siphon pads, the outer surface 101 of the siphon pad 100 is recessed into the inner shell 200, and at least two recesses 102a are provided on its inner surface 102. These recesses 102a reduce the thickness of the siphon pad 100 in this area, and when pressure is generated after liquid flows in, these recesses 102a will bulge, thereby realizing the opening and closing function of the siphon pad 100. Therefore, the siphon pad 100 no longer relies on overall expansion to open the lower lip 104, but achieves opening and closing through the bulging of the recesses 102a.

[0034] This makes the overall thickness of the siphon pad 100 can be increased, thereby improving its structural strength, liquid from the recess 102a located at the lower lip 104, not only increases the thickness of the lower lip 104, but also improves its structural strength, reduces the risk of cracking the lower lip 104, while the thicker siphon pad 100 and the inner concave outer surface 101 can increase the extrusion pressure between the lower lip 104 and the inner shell 200, to ensure better sealing, thereby improving the negative pressure effect of the first chamber 200a;

[0035] In addition, at least two recesses 102a are provided on the inner wall of the siphon pad 100, which reduces the wall thickness of the area. Compared with the overall expansion of the conventional siphon pad, the local expansion of the recess 102a can block the through hole 300b of the outer shell 300 more quickly, effectively preventing liquid from flowing out of the through hole, thereby reducing the loss of siphon effect, and thus the siphon pad has a longer service life and better siphon stability than the conventional siphon pad;

[0036] In this embodiment, as shown in Figure 3 , the outer surface 101 is uniformly concave to the inner cavity of the siphon pad 100. Uniformly concave is also conducive to the uniform outward expansion of the outer surface of the siphon pad, which can ensure that the overall structure is not easily damaged;

[0037] In this embodiment, as shown in Figure 4 , the cross section of the lower lip 104 is a uniform and continuous surface. This setting can improve the structural integrity of the lower lip during the stretching process;

[0038] As shown in Figure 4 , the lower lip 104 is hollow or solid. The hollow and solid structure of the lower lip 104 is determined by the stretchability of the lower lip. For example, if the siphon pad is not expanded enough to expand the lower lip to a large outlet, a lower lip with a suitable hollow structure can be selected. If the siphon pad is expanded to make the lower lip expand to an excessively large outlet, a solid lower lip is used to reduce the size of the outlet, thereby improving the controllability of the opening and closing;

[0039] As shown in Figure 1 , the size of the upper lip 103 is greater than the size of the lower lip 104. This can cooperate with the uniform concave of the outer surface 101 to its inner cavity, and also make the entire siphon pad 100 have a frustum shape, which can accelerate the rate at which liquid leaves the opening and closing;

[0040] As shown in Figure 1 , Figure 3 , the width of the recess 102a located on the upper lip is greater than the width of the recess 102a located on the lower lip. After the recess 102a expands, the pressure of the liquid increases and the hole through which the liquid is discharged from the lower lip becomes smaller. This is conducive to the liquid being discharged from the lower lip, further improving the rate at which liquid leaves the opening and closing;

[0041] As shown in Figure 3 ,Figure 4 As shown, the recesses 102a are distributed in an annular array on the inner surface 102, and the recesses 102a are recessed inwardly from the inner surface 102. The uniform distribution of the recesses 102a facilitates uniform outward expansion of each surface of the entire siphon pad 100, ensuring the structural integrity of the overall siphon pad 100.
