Description

Technical Field

[0001] This utility model relates to the field of water supply pipe technology, specifically to an antibacterial PE water supply pipe. Background Technology

[0002] Antibacterial PE water supply pipes use polyethylene (PE) as the base material and integrate antibacterial agents (such as silver ions and nano zinc oxide) into the pipe material through physical blending, chemical modification, or surface coating technologies. This gives the pipes the function of inhibiting the growth of bacteria, algae, and other microorganisms for a long time. These pipes are widely used in drinking water transportation, medical water supply, and other scenarios with high hygiene requirements.

[0003] In the prior art, antibacterial PE water supply pipes are usually made with an antibacterial coating on the inner wall of the pipe or by adding antibacterial particles to the manufacturing material to give the water supply pipe antibacterial properties. However, the antibacterial coating or antibacterial particles are easily detached under the scouring of water flow, which affects the antibacterial properties of the water supply pipe. In addition, some antibacterial particles are wrapped by the pipe manufacturing material and cannot come into contact with the water flow, thus failing to play an antibacterial role and affecting the antibacterial properties of the water supply pipe. Based on this, this application proposes an antibacterial PE water supply pipe. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] This utility model provides an embodiment: Please refer to Figures 1-5 An antibacterial PE water supply pipe is disclosed, comprising a water supply pipe body 1. The water supply pipe body 1 has a multi-layer structure, including an intermediate layer 6. Buffer pipes 2 are provided at both ends of the inner wall of the intermediate layer 6. Through the provision of buffer pipes 2, during use, the elastic deformation of the buffer pipes 2 can absorb the impact energy of the water flow, disperse the impact force, reduce the vibration of the water supply pipe, and reduce the impact of the water flow on the inner wall of the water supply pipe. The material of the buffer pipes 2 can be rubber, and there is no limitation herein.

[0022] An antibacterial layer 5 is disposed in the middle of the inner wall of the intermediate layer 6. The buffer pipe 2 and the antibacterial layer 5 together form the inner structure of the antibacterial PE water supply pipe. An antibacterial coating is disposed on the inner side of the antibacterial layer 5. The water supply pipe achieves antibacterial function by utilizing the antibacterial coating. The type of antibacterial coating can be selected according to requirements and is not limited here. There is a smooth transition between the buffer pipe 2 and the antibacterial layer 5. The water supply pipe can be manufactured using gradient co-extrusion technology to make the material hardness / density at the interface between the buffer pipe 2 and the antibacterial layer 5 gradually change, avoiding stress concentration at the interface.

[0023] The inner wall of the antibacterial layer 5 is uniformly provided with antibacterial lines 4. The antibacterial lines 4 have a hollow structure, and their inner cavities are filled with antibacterial particles 8. Through holes 9 are uniformly provided on the sidewalls of the antibacterial lines 4 away from the antibacterial layer 5, and these through holes 9 can intercept the antibacterial particles 8. Through the arrangement of the antibacterial lines 4, the antibacterial lines 4 can bind the antibacterial particles 8, preventing them from falling off under the scouring of water flow, thus ensuring the effectiveness of the antibacterial particles 8. Furthermore, the antibacterial particles 8 can fully contact the water in the water supply pipe, ensuring their full utilization and guaranteeing the antibacterial properties of the water supply pipe. The antibacterial lines 4 and the antibacterial layer 5 can be connected using co-extrusion molding technology. The antibacterial particles 8 can be nano-silver, zinc oxide, etc., and the specific material can be selected according to requirements; no restrictions are imposed here.

[0024] The inner wall of the antibacterial layer 5 and the side of the antibacterial line 4 away from the antibacterial layer 5 are both provided with an antibacterial coating.

[0025] An outer protective layer 7 is provided outside the intermediate layer 6 to protect the intermediate layer 6 and improve the strength of the water supply pipe. In one embodiment of this application, the outer protective layer 7 can be made of high-density polyethylene (HDPE), and the intermediate layer 6, antibacterial layer 5, and antibacterial line 4 can all be made of PE. The outer protective layer 7, intermediate layer 6, and antibacterial layer 5 can be connected by a multi-layer co-extrusion process.

[0026] The inner cavity of the water supply pipe body 1 is provided with a flow-blocking plate 3. The flow-blocking plate 3 is annular and multiple sets of flow-blocking plates 3 are arranged at intervals inside the water supply pipe body 1. The flow-blocking plate 3 is uniformly provided with mesh holes. The outer wall of the flow-blocking plate 3 is connected to the inner wall of the water supply pipe body 1. Through the setting of the flow-blocking plate 3, the flow-blocking plate 3 can reduce the impact force of water flow on the inner wall of the water supply pipe body 1 through the flow diversion effect, thereby reducing the probability of antibacterial coating peeling off. In addition, the flow-blocking plate 3 improves the strength of the water supply pipe.

[0027] In summary: When using this antibacterial PE water supply pipe, the buffer pipe 2 and the flow-blocking plate 3 work together to reduce the impact of water flow on the inner wall of the water supply pipe body 1, thereby reducing the probability of the antibacterial coating peeling off; the antibacterial coating and antibacterial particles 8 work together to sterilize the water flow in the water supply pipe, thus achieving the antibacterial function of the water supply pipe, and the antibacterial particles 8 can fully contact the water through the through hole 9, so that the antibacterial particles 8 can be fully utilized and the antibacterial properties of the water supply pipe are guaranteed.
