[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0027] This application provides an elastic sealing structure for an overflow tank sealing cap, as shown in the schematic diagram below. Figure 1-4 As shown. The elastic sealing structure of the overflow tank sealing cover includes a tank top 1, with a sealing cover 2 oppositely arranged connected to the top of the tank top 1. The tank top 1 and the sealing cover 2 are connected by a hidden hinge 3, and a sealing mechanism 4 is connected to the top of the tank top 1.

[0028] The sealing mechanism 4 includes a sealing groove 41 located at the top of the box top 1 and an air cushion 42 connected to the groove body of the sealing groove 41.

[0029] The sealing cap 2 has a locking plate 21 on its cover. The locking plate 21 has a long locking hole 22 on its plate. The long locking hole 22 fits into the air cushion 42 and is used for inserting the air cushion 42.

[0030] It should be noted that in this embodiment, the sealing cap 2 at the top of the box 1 is connected to the box 1 via a hidden hinge 3, allowing for flexible rotation for opening and closing. When the sealing cap 2 is closed, the elongated locking hole 22 of the locking plate 21 on the sealing cap 2 engages with the air cushion 42 in the sealing groove 41 at the top of the box 1, with the air cushion 42 inserted into the elongated locking hole 22. Due to the elastic properties of the air cushion 42, it expands after inflation, thus tightly filling the gap between the elongated locking hole 22 and the sealing groove 41, achieving an elastic seal between the box 1 and the sealing cap 2. The hidden hinge 3 ensures the stability of the connection between the sealing cap 2 and the box 1 without affecting the overall sealing performance and aesthetics. The cooperation between the air cushion 42 and the elongated locking hole 22 utilizes the elastic expansion of the air cushion 42 to achieve a good sealing effect, effectively preventing liquid leakage and external impurities from entering the overflow box. Compared with traditional sealing structures, the elastic sealing method is more flexible and has more reliable sealing performance.

[0031] Optionally, such as Figure 1 and Figure 2As shown, there are two long card holes 22 and two sealing grooves 41, and the cross-sections of the long card holes 22 and the sealing grooves 41 are both L-shaped.

[0032] In this embodiment, both the elongated locking holes 22 and the sealing grooves 41 are provided in twos, and both have an L-shaped cross-section. When the sealing cap 2 is closed, the two L-shaped elongated locking holes 22 respectively cooperate with the air cushions 42 in the corresponding L-shaped sealing grooves 41. The L-shaped structure allows the air cushions 42 to form contact sealing surfaces in both the horizontal and vertical directions after being inserted into the elongated locking holes 22, thereby increasing the sealing contact area.

[0033] Optionally, such as Figure 2 and Figure 3 As shown, the cross-sections of the long card hole 22 and the sealing groove 41 are both U-shaped.

[0034] In this embodiment, both the elongated locking hole 22 and the sealing groove 41 have U-shaped cross-sections, and the U-shaped structure has good containment and elastic space. When the air cushion 42 is inserted into the U-shaped elongated locking hole 22 and inflated, the inner wall of the U-shape can contact the air cushion 42 in all directions. After the air cushion 42 expands, it can fully fill the U-shaped space, forming a tight seal. The U-shaped elongated locking hole 22 and sealing groove 41 make the sealing contact more uniform, better adapt to the expansion changes of the air cushion 42, improve the flexibility and sealing performance, and at the same time, the U-shaped structure is relatively easy to process and install, which helps to reduce production and manufacturing costs.

[0035] Optionally, such as Figure 1 and Figure 2 As shown, an air pump 11 is connected to the outside of the top of the box 1, and the output end of the air pump 11 is connected to the input end of the air cushion 42 through a hose.

[0036] In this embodiment, an air pump 11 located outside the top of the enclosure 1 is connected to an air cushion 42 via a flexible hose. The air pump 11 can inflate the air cushion 42. By controlling the working time and inflation volume of the air pump 11, the expansion degree of the air cushion 42 can be adjusted, thereby adjusting the sealing force. The air pump 11 enables controllable adjustment of the sealing force, allowing for flexible changes in the tightness of the seal according to actual needs, meeting the sealing performance requirements in different scenarios, and improving the applicability and practicality of this sealing structure.

[0037] Optionally, such as Figure 1 and Figure 2 As shown, a one-way valve 13 is connected to the body of the hose.

[0038] In this embodiment, the one-way valve 13 on the hose body only allows gas to flow from the air pump 11 to the air cushion 42, preventing gas in the air cushion 42 from flowing back to the air pump 11. After the air pump 11 stops working, the one-way valve 13 can maintain the amount of gas in the air cushion 42, maintaining the expansion state and sealing effect of the air cushion 42.

[0039] Optionally, such as Figure 2 and Figure 3 As shown, a vent valve 12 is provided on the outside of the top of the box 1, and the vent valve 12 is connected to the outer surface of the top of the box 1.

[0040] In this embodiment, the vent valve 12 on the outside of the box top 1 is connected to the air cushion 42. When it is necessary to open the sealing cover 2, the vent valve 12 is opened, and the gas in the air cushion 42 can be discharged through the vent valve 12, causing the air cushion 42 to contract and release the sealing state.

[0041] Optionally, such as Figure 2 and Figure 3 As shown, a rubber pad 23 is connected to one end of the sealing cap 2.

[0042] In this embodiment, the rubber pad 23 at one end of the sealing cap 2 has a certain elasticity and sealing performance. When the sealing cap 2 is closed, the rubber pad 23 is in close contact with the surface of the box top 1, filling any possible small gaps between the sealing cap 2 and the box top 1.

[0043] The specific operation method of this utility model is as follows:

[0044] First, rotate the sealing cover 2. Since the sealing cover 2 is connected to the top of the box 1 via a hidden hinge 3, it can be rotated flexibly to the closed position. During this process, ensure that the long locking hole 22 of the locking plate 21 on the sealing cover 2 is aligned with the air cushion 42 in the sealing groove 41 at the top of the box 1, so that the air cushion 42 can be smoothly inserted into the long locking hole 22.

[0045] Next, the air pump 11 on the outside of the top of the container 1 is started, and the air pump 11 inflates the air cushion 42 through the hose. At this time, the one-way valve 13 on the hose functions, allowing gas to flow only from the air pump 11 to the air cushion 42 and preventing gas backflow. As the inflation volume increases, the air cushion 42 gradually expands, tightly filling the gap between the elongated locking hole 22 and the sealing groove 41. If the elongated locking hole 22 and the sealing groove 41 are L-shaped or U-shaped, the expanded air cushion 42 will make full contact with their inner walls, further enhancing the sealing effect. At the same time, the rubber gasket 23 at one end of the sealing cap 2 makes tight contact with the surface of the top of the container 1, forming a double seal and completing the sealing process.

[0046] When it is necessary to open the sealing cover 2, first open the vent valve 12 on the outside of the box top 1. The gas in the air cushion 42 is discharged through the vent valve 12. The air cushion 42 gradually contracts, and the tight contact between it and the long card hole 22 and the sealing groove 41 is released.

[0047] After the air cushion 42 has contracted to the appropriate degree, rotate the sealing cover 2 in the opposite direction. Since the sealing state has been released at this time, the sealing cover 2 can be easily opened to allow for inspection, maintenance and other operations inside the overflow box.

[0048] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
