Description

Technical Field

[0001] This utility model belongs to the field of bottled water technology, specifically a sealing device for the filling port of a bottled water container. Background Technology

[0002] Bottled water, as an important carrier of drinking water in modern society, is widely used in homes, offices, medical settings and other scenarios. Large-capacity standard water bottles dominate the market. Water is filled through the filling pipe at the top of the bottle, and the sealing cap at the filling pipe serves as a barrier between the bottled water and the external environment. Its performance directly affects water quality safety and ease of use.

[0003] In existing technologies, the sealing caps on bottled water filling pipes are generally designed for single use, achieving anti-counterfeiting and initial sealing through irreversible structures such as easy-tear rings and snap-fit ​​buckles. However, once these sealing caps are opened for the first time, their sealing structure (such as sealing rings and connecting buckles) will be permanently damaged. This means that when users repair the water dispenser, replace the filter, or temporarily remove the water bottle, the opened bottle opening is prone to dust and foreign objects falling in due to the lack of an effective seal, or microorganisms growing due to air contact, seriously threatening drinking water safety. To address this, we propose a sealing device for the filling opening of bottled water bottles. Utility Model Content

[0004] The purpose of this utility model is to provide a sealing device for the filling port of a bottled water container, so as to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sealing device for the filling port of a water barrel, comprising a filling pipe and a convex ring, a convex ring, and a sealing mechanism disposed outside the filling pipe, wherein the sealing mechanism includes:

[0006] The device includes a collar and an internally threaded ring fixed to the top of the collar. The internally threaded ring has internal and external threaded rings inside, and a mounting plate is provided inside the internal and external threaded rings. The inner wall of the mounting plate is provided with a rubber sealing ring. Multiple sets of T-shaped rods are fixedly provided at the bottom of the mounting plate. Multiple sets of connecting plates are slidably provided on the T-shaped rods. A plug is fixedly provided on the connecting plate to block the inside of the rubber sealing ring.

[0007] Preferably, a compression spring is sleeved on the outside of the T-shaped rod, and the top of the compression spring is fixedly connected to the bottom of the mounting plate, and the bottom of the compression spring is fixedly connected to the T-shaped rod.

[0008] Preferably, the rubber sealing ring is externally fixed with an inner ring, and the inner ring is fixedly connected to the mounting plate by two sets of screws.

[0009] Preferably, two sets of one-way valves are embedded inside the mounting plate.

[0010] Preferably, a filter element is provided above the one-way valve, and the filter element includes an activated carbon filter element disposed above the one-way valve.

[0011] Preferably, the activated carbon filter element is externally fixed with an installation ring, and the installation ring is fixedly connected to the installation plate by two sets of screws.

[0012] Preferably, a film is adhered to the top of the internal threaded ring.

[0013] Preferably, the convex ring, the convex ring and the filling pipe are integrally formed.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) This utility model, through its designed sealing mechanism, allows the smart head tip to open the cap when the bottled water is installed on the water dispenser. The compression spring then compresses the cap, separating it from the rubber sealing ring and allowing water to flow through. When the water bottle is removed, the compression spring returns to its original position, pushing the cap to adhere to the rubber sealing ring and automatically blocking the water flow channel. This avoids the problem of traditional disposable sealing caps failing to reseal after opening. It is suitable for mid-way maintenance, replacement of the water dispenser's internal filter, or temporary removal of the bottle. When installing the water bottle, the smart head automatically opens the cap, making it plug-and-play. When removing the bottle, the compression spring drives the cap to close automatically. The operation is simple and adaptable to the rapid installation needs of home, office, and other scenarios.

[0016] (2) The filter element designed in this utility model can filter the water that flows back into the water barrel through the gap between the plug and the rubber sealing ring during the transportation of bottled water due to squeezing or tilting. The activated carbon filter element in the filter element can filter the water that flows back into the water barrel through the one-way valve. The filter element and the sealing mechanism work together to avoid waste and improve the water quality of the water that flows back into the bottled water. Attached Figure Description

Detailed Implementation

[0025] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Example 1

[0027] Please see Figures 1-7 This utility model provides a technical solution: a sealing device for the filling port of a water bottle, including a filling pipe 100 and a convex ring 101 and a convex ring 102 disposed outside the filling pipe 100. A sealing mechanism is provided outside the filling pipe 100, and the sealing mechanism includes:

[0028] A collar 200 is fitted around the outside of the filling pipe 100, and an internally threaded ring 202 is fixed to the top of the collar 200. The internally threaded ring 202 is internally connected to internally and externally threaded rings 203 via threads. After the water in the bucket is used up, the internally and externally threaded rings 203, along with the mounting plate 204, rubber sealing ring 207, and T-shaped rod 209, can be removed by rotating them upwards. These components can then be cleaned, disinfected, and reinstalled on the filling pipes 100 of other buckets, achieving reuse and reducing material waste. The internally threaded ring 202 and collar 200 are directly removed from the filling pipe 100 and not reused. The inner wall of the internally and externally threaded rings 203 is also connected to a screw cap 213 via threads, further enhancing sealing. To achieve a sealing effect and prevent water from flowing out of the water bucket and causing waste, an installation plate 204 is fixedly installed inside the internal and external threaded ring 203. A rubber sealing ring 207 is installed on the inner wall of the installation plate 204. The inner diameter of the rubber sealing ring 207 is slightly larger than the diameter of the smart head on the water dispenser. When the water bucket is installed on the water dispenser, the sharp end of the smart head passes through the inside of the rubber sealing ring 207. The rubber sealing ring 207 is squeezed by the smart head, which increases the sealing effect between it and the smart head. Multiple sets of T-shaped rods 209 are fixedly installed at the bottom of the installation plate 204. Multiple sets of connecting plates 212 are slidably installed on the T-shaped rods 209. A plug 205 is fixedly installed on the connecting plate 212 to block the inside of the rubber sealing ring 207.

[0029] A compression spring 211 is sleeved on the outside of the T-shaped rod 209, and the top of the compression spring 211 is fixedly connected to the bottom of the mounting plate 204, and the bottom of the compression spring 211 is fixedly connected to the T-shaped rod 209.

[0030] An inner ring 206 is fixedly provided on the outside of the rubber sealing ring 207, and the inner ring 206 is fixedly connected to the mounting plate 204 by two sets of screws. The inner ring 206 can be replaced by screws, and thus the rubber sealing ring 207 can be replaced, preventing the rubber sealing ring 207 from being damaged after long-term use.

[0031] Two sets of one-way valves 210 are embedded inside the mounting plate 204. The one-way valves 210 can allow water located between the mounting plate 204 and the cap 213 to flow into the water tank, while the water inside the water tank will not flow out.

[0032] A film 201 is attached to the top of the internal threaded ring 202. The film 201 can prevent contamination of the inside of the sealing device during transportation.

[0033] Example 2

[0034] Please refer to Example 1. Figures 1-7A filter element is provided above the one-way valve 210. The filter element includes an activated carbon filter element 300 located above the one-way valve 210. The upper surface of the activated carbon filter element 300 is in contact with the bottom of the rubber sealing ring 207.

[0035] An installation ring 301 is fixedly installed on the outside of the activated carbon filter element 300. The installation ring 301 is fixedly connected to the installation plate 204 by two sets of screws. The installation ring 301 can be replaced by screws, and thus the activated carbon filter element 300 can be replaced, to avoid the activated carbon filter element 300 from having poor filtration effect after long-term use.

[0036] In this embodiment, the convex ring 101, the convex ring 102 and the filling pipe 100 are integrally formed.

[0037] Working principle and usage process of this utility model:

[0038] In use, the water bucket is installed on the water dispenser. First, the collar 200 is inserted into the filling tube 100 from above. At this point, the PP material collar 200 temporarily bends and deforms due to the influence of the convex rings 101 and 102. After passing the convex rings 101 and 102, the external force is removed, and the collar 200 elastically rebounds and locks the convex rings 101 and 102. At this point, the collar 200 is installed on the outside of the filling tube 100. Next, the film 201 is peeled off from the top of the internal threaded ring 202, and then the cap 213 is unscrewed and removed. Then, the water bucket is inverted and inserted into the smart head with a pointed top on the water dispenser. The sharp point of the smart head... The end of the device is inserted into the inner ring 206. During insertion, the end of the device pushes against the cap 205, pushing the cap 205 towards the filling pipe 100 (that is, away from the rubber sealing ring 207). This causes the connecting plate 212 to move away from the mounting plate 204. At this time, the connecting plate 212 slides on the T-shaped rod 209. The compression spring 211 is compressed by the connecting plate 212. When the cap 205 moves, a gap is created between the cap 205 and the rubber sealing ring 207. The water in the water bucket can then flow out of the water dispenser through the gap from the rubber sealing ring 207. The water bucket can then be installed on the water dispenser, and the water dispenser can be used normally.

[0039] When the water dispenser is repaired, the filter is replaced, or the water bottle is temporarily removed, the water bottle is removed from the water dispenser. During the removal process, the smart head end on the water dispenser begins to detach from the inside of the rubber sealing ring 207 and no longer pushes out the plug 205. Then, the compression spring 211 begins to reset, pushing the connecting plate 212 to move closer to the mounting plate 204. The connecting plate 212 drives the plug 205 to move closer to the rubber sealing ring 207. Subsequently, the top of the plug 205 contacts the bottom of the rubber sealing ring 207, and through the compression of the compression spring 211, the plug 205 and the rubber sealing ring 207 are fitted together, eliminating the gap between the plug 205 and the rubber sealing ring 207. At this time, the water in the water bottle will not flow out from the rubber sealing ring 207.

[0040] Furthermore, if the water bottle is squeezed during transportation (before it is installed on the water dispenser), and some water flows from the gap between the plug 205 and the rubber sealing ring 207 to the area between the plug 205 and the screw cap 213, the screw cap 213 can block the leaking water and prevent it from flowing outside the sealing device. At the same time, the water flowing out between the plug 205 and the screw cap 213 will flow back into the water bottle through the one-way valve 210, thus avoiding water waste.

[0041] Meanwhile, the water flowing back into the water tank from the one-way valve 210 will be filtered by the activated carbon filter element 300 before flowing back into the water tank. The activated carbon filter element 300 filters the water so that the water flowing back into the water tank will not pollute the water in the water tank.

[0042] The above embodiments are only used to illustrate the technical methods of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of this utility model without departing from the spirit and scope of the technical methods of this utility model.
