Description

Technical Field

[0001] The utility model relates to the technical field of filling and conveying tubes, in particular to an eyewash liquid filling and conveying tube. Background Art

[0002] In many industrial and medical environments, eyewash is an important safety protection product, and the efficiency and safety of its filling and delivery process are extremely important. Eyewash filling delivery tube is a device used to deliver this liquid from the storage container to the point of use or filling machine. Reasonable delivery tube design is essential to ensure the quality of eyewash, avoid contamination and reduce waste.

[0003] However, the existing eyewash liquid filling and delivery tubes have some obvious shortcomings. First, the performance of traditional delivery tube materials may deteriorate due to chemical corrosion or physical wear during long-term use, which not only affects the delivery efficiency, but also may cause leakage or contamination of the eyewash liquid. In addition, when delivering eyewash liquid, traditional pipes are usually unable to effectively prevent the backflow or dripping of liquid after the delivery stops, which not only causes waste of eyewash liquid, but may also affect the cleanliness and safety of the environment to a certain extent.

[0004] Secondly, most existing pipelines lack sufficient structural strength and are prone to deformation or rupture during high-pressure transportation, which can seriously affect the reliability and safety of the transportation system. These pipelines also often lack sufficient flexibility, making them inconvenient during installation and maintenance, especially in environments with limited space.

[0005] Therefore, in response to these problems, the design of the new eyewash filling and delivery tube adopts a multi-layer structure to improve the chemical resistance and physical durability of the material. At the same time, through the innovative anti-drip design, it effectively reduces the leakage and dripping of the eyewash liquid, and significantly improves the utilization rate and overall environmental performance of the eyewash liquid. This improved design not only solves the defects of the existing technology, but also provides higher safety and economic benefits. Utility Model Content

[0006] In order to overcome the defects of the prior art, the utility model aims to provide an eyewash solution filling and conveying tube.

[0007] To achieve the above-mentioned purpose, the technical solution of the utility model is implemented as follows: an eyewash liquid filling and delivery tube, comprising an outer protective layer distributed on the outermost side, an inner reinforcing layer is arranged on the inner side of the outer protective layer, an inner fixed layer is arranged on the inner side of the inner reinforcing layer, an anti-drip liquid conducting layer is arranged on the inner side of the inner fixed layer, and the inner wall of the anti-drip liquid conducting layer is provided with four nipple-shaped convex strips protruding toward the central axis of the pipeline, and the four nipple-shaped convex strips squeeze the space formed inside the anti-drip liquid conducting layer into a cross-shaped liquid conducting channel.

[0008] As a preferred technical solution of the present utility model, the outer protective layer is made of PVC material.

[0009] As a preferred technical solution of the present utility model, the inner reinforcement layer is made of fluororubber.

[0010] As a preferred technical solution of the utility model, a plurality of reinforcing ribs are evenly distributed inside the inner reinforcing layer along its length direction.

[0011] As a preferred technical solution of the utility model, the reinforcing ribs are all woven from steel wires.

[0012] As a preferred technical solution of the present utility model, the inner fixing layer is made of PVC material.

[0013] As a preferred technical solution of the present utility model, the drip-proof liquid-conducting layer is made entirely of silicone material.

[0014] As a preferred technical solution of the utility model, the spacing between adjacent nipple-shaped convex strips is set to 2 mm.

[0015] As a preferred technical solution of the utility model, the spacing between the relative nipple-shaped convex strips is set to 4 mm.

[0016] The beneficial effects of the utility model are embodied in:

[0017] The design of this eyewash filling delivery tube demonstrates a high degree of innovation and practicality, mainly because its structural composite layer design can effectively improve the delivery efficiency and significantly reduce the waste of eyewash solution. The PVC material of the outer protective layer provides the necessary chemical resistance and wear resistance, allowing the delivery tube to adapt to different working environments. The fluororubber and steel wire braided reinforcement of the inner reinforcement layer increase the pressure resistance and corrosion resistance, ensuring that the performance of the delivery tube is not affected in high pressure and harsh chemical environments.

[0018] The use of the inner fixing layer not only maintains the stability of the internal structure, but also ensures the overall flexibility of the delivery tube, so that the durability of the structure will not be sacrificed due to the flexibility of the tube. The most innovative anti-drip liquid guide layer cleverly uses the tension of the eyewash liquid to prevent liquid leakage through its unique silicone material and milky convex strip design, and locks the residual liquid after the delivery stops, thereby minimizing waste. This design not only improves filling efficiency, but also further improves environmental performance by reducing the waste of eyewash liquid.

[0019] In general, this eyewash filling and delivery tube is an important optimization of existing technologies. Through its multi-layer innovative structural design, it not only ensures the functionality and durability of the delivery tube, but also brings significant improvements in environmental protection and economic benefits. This design concept and technical implementation provide valuable references for other similar liquid delivery systems, demonstrating the great potential of industrial design in improving product performance and efficiency.

[0028] The utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] It should be noted that if the utility model embodiments involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0030] In addition, "multiple" means more than two. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0031] Please refer to the instruction manual Figure 1-Figure 3 The utility model provides an eyewash liquid filling and delivery tube, the structural design of which is intended to optimize the delivery efficiency of the eyewash liquid and reduce waste. The delivery tube includes an outer protective layer 1, an inner reinforcement layer 2, an inner fixing layer 3 and an anti-drip liquid guide layer 4 from the outside to the inside.

[0032] The outer protective layer 1 is made of PVC material, which has good chemical resistance and wear resistance, and protects the internal structure from the influence of the external environment. The selection of PVC material ensures that the conveying pipe can maintain stable performance in various working environments.

[0033] The inner reinforcement layer 2 is made of fluororubber, which has excellent high temperature resistance and corrosion resistance. Several reinforcing ribs 21 made of braided steel wire are evenly distributed along the length of the inner layer to enhance the overall strength and pressure resistance of the tube body. The chemical corrosion resistance of the fluororubber material ensures that the delivery tube will not react chemically when it comes into contact with the eyewash solution, while the braided steel wire reinforcing ribs provide additional structural support, ensuring the stability and durability of the delivery tube under high pressure.

[0034] The inner fixing layer 3 is also made of PVC material, and its function is to fix the inner reinforcement layer 2 and the anti-drip liquid guiding layer 4 to ensure the close connection between the layers. The PVC material of the inner fixing layer has good flexibility and tensile resistance, and can provide sufficient structural stability without affecting the overall flexibility of the conveying pipe.

[0035] The anti-drip liquid guiding layer 4 is made of silicone material as a whole, which has good elasticity and sealing. The elasticity of the silicone material enables the delivery tube to maintain good sealing performance when it is bent or twisted, preventing the eyewash solution from leaking. The inner wall of the anti-drip liquid guiding layer 4 is provided with four milky ridges 41 protruding toward the central axis of the pipeline. The design of these milky ridges 41 cleverly utilizes the self-tension of the eyewash solution. The four milky ridges squeeze the space formed inside the anti-drip liquid guiding layer 4 into a cross-shaped liquid guiding channel. The spacing between adjacent milky ridges 41 is set to 2 mm, and the spacing between the relative milky ridges 41 is set to 4 mm. This design ensures that after a single filling and infusion is stopped, the eyewash solution retained in the tube body will not fall due to gravity, thereby avoiding the waste of eyewash solution. The increase in the gap between the milky ridges 41 and the contact area with the eyewash solution enables the eyewash solution to complete the locking operation of the eyewash solution retained in the delivery tube with the help of its own tension, ensuring the effective use of the eyewash solution.
