[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] Obviously, many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Please see Figure 1-3 This utility model provides a plasticized purified water supply pipe, including a main pipe 1 and an adjusting pipe 5 threadedly connected to the main pipe 1. Both the main pipe 1 and the adjusting pipe 5 have hollow layers on their inner walls, and the hollow layers are filled with antibacterial filler 13. One end of the main pipe 1 is fixedly connected to a threaded sleeve 3, and the other end of the main pipe 1 is fixedly connected to a first flange 2. One end of the adjusting pipe 5 is fixedly connected to a threaded post 4. A purification filter plate 14 is placed inside the threaded sleeve 3, and the threaded post 4 is threadedly inserted into the inside of the threaded sleeve 3. One end of the regulating pipe 5 is fixedly connected to a sealing ring 10. One end of the regulating pipe 5 is slidably connected to a secondary pipe 11, and an adjusting slot 15 is provided on one side of the secondary pipe 11. One end of the sealing ring 10 is slidably inserted into the adjusting slot 15, and one end of the secondary pipe 11 is fixedly connected to a second flange 12. A first fixing ring 6 and a second fixing ring 8 are respectively fixedly sleeved on the outer surfaces of the regulating pipe 5 and the secondary pipe 11. A screw 7 is threaded between the first fixing ring 6 and the second fixing ring 8, and a knob 9 is fixedly connected to one end of the screw 7. The second flange 12 and the first flange 2 can connect the entire device. At this time, the purification filter plate 14, which is attached to one end of the threaded insert 4 inside the threaded sleeve 3, can perform water purification and filtration. It should be noted that, in order to cooperate with the purification work, the purification filter plate 14 can also be set as a purification filter element. After the entire device is installed, the sealing insert 10 is fixed in the position of being inserted into the adjusting slot 15 by the threaded connection between the screw 7 and the first fixing ring 6. This increases the overall sealing performance of the sealing insert 10 and provides an adjustable seal. When the purification filter plate 14 has been working on water purification for a long time, if the purification efficiency decreases, the water supply can be stopped first. By rotating the knob 9, the screw 7 is suspended, and by rotating the adjusting tube 5, the threaded insert 4 is rotated away from the inside of the threaded sleeve 3, so that the threaded insert 4 can be taken out. The sliding insertion of the sealing ring 10 inside the adjusting slot 15 provides space for the removal of the purification filter plate 14. Thus, after the device is installed, the purification filter plate 14 used for purification can be replaced in time, and the operation is simple and efficient.

[0021] In order to more effectively inhibit bacterial growth and improve the overall service life of the device, the antibacterial filler 13 is made of silver ion masterbatch, and the main pipe 1 and the regulating pipe 5 are both made of HDPE, and the inner walls of the main pipe 1 and the regulating pipe 5 are both heat-fused with PPR.

[0022] In order to better place the purification filter plate 14 and use the purification filter plate 14 to purify and filter the water source, the diameter of the threaded sleeve 3 is larger than the diameter of the main pipe 1, and the purification filter plate 14 is slidably disposed inside the threaded sleeve 3, and the two sides of the purification filter plate 14 are respectively attached to one side of the main pipe 1 and the threaded insert 4.

[0023] Furthermore, in order to better provide space for the rotation of the threaded plug 4 after the device is installed, the length of the sealing ring 10 is greater than the length of the threaded plug 4, and the outer surface of the sealing ring 10 is in contact with the inner wall of the adjusting slot 15.

[0024] Furthermore, in order to increase the sealing performance while providing room for rotation, the diameter of the sealing ring 10 is larger than the diameter of the regulating tube 5, and the sealing ring 10 is fixed to the outside of one end opening of the regulating tube 5.

[0025] In order to better control the position of the sealing ring 10 inserted into the adjustment slot 15, one end of the screw 7 is threaded into the inside of the first fixing ring 6, the other end of the screw 7 is threaded into the inside of the second fixing ring 8, and the knob 9 is fixed to one end of the screw 7 outside the second fixing ring 8.

[0026] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0027] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0028] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
