Description

Technical Field

[0001] This utility model specifically relates to a silicone tube connector for a water dispenser. Background Technology

[0002] A water dispenser is a device that heats or cools bottled purified water (or mineral water) for convenient drinking. Bottled water is placed on top of the machine for use with bottled water. During operation, silicone tubing is used as a conduit to connect the various internal units of the water dispenser.

[0003] However, conventional silicone tube connectors in water dispensers simply use a single silicone tube directly fitted onto the metal nozzle. Although the silicone tube can stay firmly attached to the metal nozzle for a short time due to its own tension, it may become loose and leak after prolonged use, or even come off completely. In addition, the silicone tube, working inside the water dispenser for a long time, is susceptible to leakage due to temperature and humidity changes, and may also be exposed to chemicals emitted from the metal casing, which is detrimental to drinking water health. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a silicone tube connector for water dispensers.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A silicone hose connector for a water dispenser includes a silicone hose and silicone sleeves fitted at both ends of the silicone hose. The silicone hose consists of a silicone tube body and sleeve heads integrally formed at both ends. The silicone sleeves are fitted onto the sleeve heads and include a silicone sleeve body and several annular grooves formed on the inner wall of the silicone sleeve body. An anti-detachment ring is integrally formed on the edge of the sleeve head, and several annular protrusions are provided on its outer surface. The annular protrusions and annular grooves engage to form an anti-detachment sealing structure.

[0007] Preferably, the surface of the silicone tube is sequentially laminated with an anti-seepage protective film layer and an anti-adhesion film layer.

[0008] Furthermore, the impermeable protective membrane layer is a polytetrafluoroethylene membrane layer.

[0009] Furthermore, the anti-detachment adhesive film layer is a modified silicone pressure-sensitive adhesive film layer.

[0010] Preferably, the annular protrusion is a continuous closed-loop structure with a semi-circular cross-section that matches the curvature of the annular groove.

[0011] Preferably, the number of annular grooves is the same as the number of annular protrusions.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. The annular protrusion on the sleeve head and the annular groove on the inner wall of the silicone sleeve form a precise locking structure, which can effectively resist the axial separation force caused by water pressure, vibration or accidental pulling during the use of the silicone hose, ensuring a firm connection between the sleeve head and the water dispenser nozzle. In addition, the tight locking of the annular protrusion and the annular groove forms multiple continuous anti-detachment lines, allowing the silicone sleeve to press tightly against the sleeve head. This not only prevents the sleeve head from coming loose from the water dispenser nozzle, but also enhances the sealing between the sleeve head and the water dispenser nozzle, effectively preventing water leakage from the connection point.

[0014] 2. The anti-seepage protective membrane layer composited on the surface of the silicone tube is the key. Since silicone itself has a certain degree of air and water permeability, the anti-seepage protective membrane layer can effectively prevent water from seeping outward through the silicone tube wall or water vapor from seeping inward.

[0015] 3. The anti-detachment adhesive membrane layer located outside the anti-seepage protective membrane layer provides additional adhesion, which can firmly adhere to the components connected to it, providing strong radial gripping force to prevent the joint from rotating or axially slipping at the interface. In addition, it can also prevent the anti-seepage protective membrane layer from loosening, so that the silicone tube body maintains good anti-seepage protection performance.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0022] Example

[0023] A silicone tube connector for a water dispenser, such as Figure 1-5 As shown, it includes a silicone tube 1 and silicone sleeves 2 fitted onto both ends of the silicone tube 1.

[0024] The silicone hose 1 consists of a silicone tube body 11 and sleeve heads 12 integrally formed at both ends. The surface of the silicone tube body 11 is sequentially laminated with a waterproof protective membrane layer 111 and an anti-detachment adhesive membrane layer 112. The sleeve head 12 has an anti-detachment ring 121 integrally formed on its edge, and its outer surface is provided with several annular protrusions 122. The annular protrusions 122 engage with the annular grooves 22 to form an anti-detachment sealing structure.

[0025] The silicone sleeve 2 is mounted on the sleeve head 12. It includes a silicone sleeve body 21 and several annular grooves 22 formed on the inner wall of the silicone sleeve body 21.

[0026] In this embodiment, the number of annular grooves 22 is the same as the number of annular protrusions 122. The annular protrusions 122 are continuous closed-loop structures with a semi-circular cross-section that matches the curvature of the annular grooves 22.

[0027] It should be further explained that the annular protrusion 122 on the fitting head 12 and the annular groove 22 on the inner wall of the silicone sleeve 2 form a precise locking structure, which can effectively resist the axial separation force generated by water pressure, vibration or accidental pulling during the use of the silicone hose, ensuring that the fitting head 12 is firmly connected to the water dispenser nozzle. In addition, the tight locking of the annular protrusion 122 and the annular groove 22 forms multiple continuous anti-detachment lines, which allows the silicone sleeve 2 to press tightly against the fitting head 12. This not only prevents the fitting head 12 from loosening from the water dispenser nozzle, but also enhances the sealing between the fitting head 12 and the water dispenser nozzle, effectively preventing water leakage from the connection point.

[0028] In this embodiment, the impermeable protective membrane layer 111 is a polytetrafluoroethylene membrane layer.

[0029] It should be further explained that the anti-seepage protective membrane layer composited on the surface of the silicone tube is the key. Since silicone itself has a certain degree of air and water permeability, the use of polytetrafluoroethylene membrane layer for anti-seepage protective membrane layer can effectively prevent water from seeping outward through the silicone tube wall or water vapor from seeping inward.

[0030] In this embodiment, the anti-detachment adhesive film layer 112 is a modified silicone pressure-sensitive adhesive film layer.

[0031] It should be further explained that the modified silicone pressure-sensitive adhesive film layer located outside the anti-seepage protective membrane layer provides additional adhesion, which can firmly adhere to the components connected to it, providing strong radial gripping force to prevent the joint from rotating or axially slipping at the interface. In addition, it can also prevent the anti-seepage protective membrane layer from loosening, so that the silicone tube body maintains good anti-seepage protection performance.

[0032] In summary, this utility model systematically solves the problems of leakage prevention, axial loosening prevention, and radial slippage or rotation prevention of silicone tube joints in water dispensers through a three-layer composite structure consisting of a silicone tube body 11, an anti-leakage protective membrane layer 111, and an anti-detachment adhesive membrane layer 112, and a mechanical interlocking structure consisting of an anti-detachment ring 121, annular protrusion 122, and annular groove 22. Figure 1-5 The above structural features are clearly shown, especially the engagement details of the fitting head 12 and the silicone sleeve 2, as well as the composite layer structure of the tube wall.

[0033] Taking the connection of a water dispenser nozzle as an example, the installation steps for the silicone hose connector include the following:

[0034] S1. Confirm that the fitting heads 12 at both ends of the silicone hose 1 are free from deformation and damage, the annular protrusions 122 are intact, and the annular grooves 22 on the inner wall of the silicone sleeve 2 are clean and free of foreign objects. Since the anti-detachment ring 121 is usually located at the outermost end and plays a limiting role, it is also necessary to confirm that the fitting heads 12 of the silicone hose 1 are inserted into the silicone sleeve 2 in the correct direction.

[0035] S2. Align the fitting head 12 with the water dispenser nozzle, ensuring the axis is aligned. Push the fitting head 12 smoothly and continuously along the axis of the water dispenser nozzle until it reaches the bottom or the designed stop point of the water dispenser nozzle.

[0036] S3. After connecting the fitting head 12 to the water dispenser nozzle, align the open end of the silicone sleeve 2 with the fitting head 12. Pinch the body of the silicone sleeve 2 with your thumb and forefinger and push it in evenly and slowly along the axis of the fitting head 12. When the silicone sleeve 2 is fitted, you will feel obvious resistance at different stages. This is because the annular protrusion 122 needs to be squeezed and deformed to pass through the inner wall of the silicone sleeve 2 and enter the annular groove 22. When you hear a slight "click" or feel a stutter, it usually means that the first protrusion has been successfully inserted into the groove. Continue to push in evenly until the bottom of the silicone sleeve 2 completely abuts against the anti-detachment ring 121. At this time, all the annular protrusions 122 should be inserted into the corresponding annular grooves 22 to form a tight and continuous anti-detachment sealing line.

[0037] S4. Gently try to pull the silicone sleeve 2 and silicone hose 1 axially. The connection should feel firm with no obvious displacement. Visually check whether the silicone sleeve 2 is fully inserted without any misalignment. The docking assembly is now complete.

[0038] The above embodiments of this utility model are not intended to limit the scope of protection of this utility model. The implementation of this utility model is not limited thereto. All other modifications, substitutions or alterations made to the above structure of this utility model based on the above content of this utility model and in accordance with the common technical knowledge and conventional means in the field, without departing from the basic technical idea of ​​this utility model, shall fall within the scope of protection of this utility model.
