Description

Technical Field

[0001] This utility model relates to the field of PE water supply pipe technology, and in particular to a PE water supply pipe with antibacterial filtration function. Background Technology

[0002] PE pipe, also known as polyethylene pipe, is a type of plastic pipe characterized by its corrosion resistance, impact resistance, and long service life. It is mainly used for water supply and gas pipes.

[0003] Chinese Patent Announcement No. CN 212056295 U discloses a utility model patent entitled "A PE water supply pipe capable of filtering impurities", which includes a water supply pipe. A retaining ring is fixedly installed on the right side of the water supply pipe. A water passage hole is opened on the inner side of the retaining ring. A first connecting ring is fixedly installed on the outer side of the water pipe. A first water-blocking pad is fixedly installed on the inner side of the first connecting ring. An external threaded ring is fixedly installed on the outer side of the first connecting ring.

[0004] This PE water supply pipe, which can filter impurities, allows the original left-side water supply pipe to be connected to the added filter pipe without twisting or rotating by setting a retaining ring, a water passage hole, a first connecting ring, a first water-blocking pad, and an external threaded ring. The internal threaded ring and the second connecting ring facilitate the connection between the left-side water supply pipe and the filter pipe. The third and fourth connecting rings facilitate the connection between the filter pipe and the right-side water supply pipe, thus achieving convenient installation on the original water pipe foundation.

[0005] However, the aforementioned PE water supply pipes primarily rely on filter cartridges to filter impurities. During use, impurities in the water continuously adhere to the filter cartridge. Over time, the filter pores on the cartridge gradually become clogged, quickly leading to blockage of the entire pipe.

[0006] Therefore, this application proposes a PE water supply pipe with antibacterial filtration function, which filters impurities in the water while making the pipe less prone to clogging. Utility Model Content

[0007] In view of the shortcomings of the prior art mentioned above, the purpose of this utility model is to provide a PE water supply pipe with antibacterial filtration function to solve the problem of easy clogging of the filter screen of existing PE water supply pipes mentioned in the prior art.

[0008] To achieve the above and other related objectives, this utility model provides a PE water supply pipe with antibacterial filtration function, including a water pipe mechanism and a filtration mechanism. The filtration mechanism is obliquely inserted from the outside of the water pipe mechanism into the inside of the water pipe mechanism to filter impurities in the water.

[0009] The water pipe mechanism specifically includes a main water supply pipe, and a branch pipe is inclinedly arranged on the outer surface of the main water supply pipe. The filter mechanism is inserted into the main water supply pipe from the inside of the branch pipe, and the outer surface of the filter mechanism is inclinedly washed by the water flow in the main water supply pipe.

[0010] Preferably, a filter element fixing head is provided at the end of the diversion pipe away from the main water supply pipe, and the end of the filter mechanism cooperates with the filter element fixing head to fix the filter mechanism.

[0011] Preferably, the filtration mechanism includes a filter element, and the filter element has a cavity inside;

[0012] The filter element has an inlet on the side facing the main water supply pipe inlet, and the filter element is covered with filter holes. The inlet is inclined along the axis of the branch pipe.

[0013] Preferably, the diameter of the filter element is equal to the inner diameter of the main water supply pipe;

[0014] The bottom of the water inlet is flush with the bottom of the main water supply pipe, and the top of the water inlet is flush with the top of the main water supply pipe.

[0015] Preferably, the outer surface of the main water supply pipe is provided with a limiting bracket coaxially arranged with the branch pipe, and the limiting bracket is in communication with the interior of the main water supply pipe;

[0016] The lower end of the filter element is inserted into the interior of the limiting device and is limited.

[0017] Preferably, an impurity trapping cylinder is provided in the cavity inside the filter element, and the impurity trapping cylinder is located above the water inlet.

[0018] Preferably, the impurity trapping cylinder has an inverted trumpet-shaped structure, and a gap is left between the outer surface of the impurity trapping cylinder and the inner wall of the filter element.

[0019] Preferably, the upper end of the filter element is provided with a sealing head, the sealing head including a threaded head that is threadedly connected to the filter element fixing head, and a nut is provided at the end of the threaded head, the nut being placed outside the filter element fixing head.

[0020] Preferably, the inner wall of the main water supply pipe is provided with an antibacterial coating, and the antibacterial coating has a smooth surface.

[0021] Preferably, the antibacterial coating is a silver ion layer.

[0022] As described above, the PE water supply pipe with antibacterial filtration function of this utility model has the following beneficial effects:

[0023] 1. This utility model uses a diversion pipe installed at an angle on the main water supply pipe, and a filter mechanism is inserted at an angle from the diversion pipe into the main water supply pipe to filter impurities in the water. When water flows through the main water supply pipe, the water flow will obliquely wash the outer surface of the filter mechanism, making it difficult for impurities in the water to adhere to the outer surface of the filter mechanism. This achieves the effect of filtering impurities in the water while reducing the clogging of the filter mechanism by impurities.

[0024] 2. This utility model uses an inclined filter mechanism installed in the main water supply pipe. When the water flows, it impacts the filter mechanism at an angle. When the main water supply pipe is suddenly connected to or disconnected from water, the impact force generated by the water flow is dissipated by the inclined filter mechanism, avoiding direct impact on the filter mechanism. This reduces the impact of water hammer effect on the filter mechanism and valve, thereby improving its service life.

[0025] 3. This utility model sets an impurity interception cylinder in the cavity inside the filter element. When impurities inside the filter element are impacted by water flow, the impurities will float upward along the inner radial direction of the filter element and pass through the impurity interception cylinder. As the inner diameter of the impurity interception cylinder gradually decreases, the impurities are intercepted in the gap between the outer surface of the impurity interception cylinder and the inside of the filter element, thereby further preventing impurities from clogging the filter holes.

[0026] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value. Attached Figure Description

[0036] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0037] Please see Figures 1 to 6 It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and are not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0038] like Figures 1-3 As shown, this utility model provides a PE water supply pipe with antibacterial filtration function, including a water pipe structure 1 and a filter structure 2. Water flows in from one end of the water pipe structure 1, and the filter structure 2 is obliquely inserted from the outside of the water pipe structure 1 into the inside of the water pipe structure 1 to filter the water flowing inside the water pipe structure 1, thereby intercepting impurities in the water. The filter structure 2, which is obliquely inserted into the water pipe structure 1, forms a tangential angle with the direction of water flow. Therefore, when the water flows through the filter structure 2, it will obliquely wash the outer surface of the filter structure 2.

[0039] The water pipe mechanism 1 specifically includes a main water supply pipe 11, which serves as the primary channel for water flow. A branch pipe 12 is obliquely arranged on the outer surface of the main water supply pipe 11, communicating with its interior. A filter mechanism 2 is inserted into the main water supply pipe 11 from inside the branch pipe 12, creating a tangential angle between the outer surface of the filter mechanism 2 and the direction of water flow. As water flows through, the outer surface of the filter mechanism 2 is obliquely washed by the water flow in the main water supply pipe 11, allowing impurities adhering to its surface to detach under the impact of the water flow, preventing impurities from accumulating and clogging the channels in the main water supply pipe 11.

[0040] like Figure 2 and Figure 3As shown, in some embodiments, a filter element fixing head 13 is provided at the end of the diversion pipe 12 away from the main water supply pipe 11. The end of the filter mechanism 2 cooperates with the filter element fixing head 13 to fix the filter mechanism 2, thereby making the filter mechanism 2 stably placed in the diversion pipe 12 and preventing the filter mechanism 2 from falling off the diversion pipe 12 and leaking water due to the impact force of water flow or unexpected situations. At the same time, the filter mechanism 2 can be easily disassembled for cleaning when removing impurities.

[0041] like Figure 2 and Figure 4 As shown, in some embodiments, the filter mechanism 2 of this utility model includes a filter element 21, the filter element 21 having an internal cavity. An inlet 22 is provided on the side of the filter element 21 facing the main water supply pipe 11 inlet, and filter holes 23 are distributed throughout the filter element 21. When filtering water, the water flows into the interior of the filter element 21 through the inlet 22. Impurities in the water are trapped inside the filter element 21, while the water continues to flow backward through the filter holes 23. The inlet 22 is inclined along the axial direction of the diversion pipe 12 to increase the opening area of ​​the inlet 22. Simultaneously, the water flow, when passing through the inlet 22, can impact the interior of the filter element 21 at an angle, achieving the removal of adhering substances.

[0042] like Figure 2 As shown, in some embodiments, the diameter of the filter element 21 of this utility model is equal to the inner diameter of the main water supply pipe 11, so that the filter element 21 can completely cut off the inside of the main water supply pipe 11, thereby improving the efficiency of the filter element 21 in filtering impurities in the water.

[0043] The bottom of the inlet 22 is flush with the inner bottom of the main water supply pipe 11, and the top of the inlet 22 is flush with the inner top of the main water supply pipe 11. This ensures that the connection between the inlet 22 and the main water supply pipe 11 is flush, preventing impurities in the water from being trapped on the outside of the filter element 21 when the water flows through.

[0044] like Figure 2 and Figure 3 As shown, in some embodiments, the outer surface of the main water supply pipe 11 of this invention is provided with a limiting support 14 coaxially arranged with the branch pipe 12, and the limiting support 14 is in communication with the interior of the main water supply pipe 11. The lower end of the filter element 21 is inserted into the interior of the limiting support 14 and is limited. This provides support to the bottom of the filter element 21, thereby improving the impact resistance of the filter element 21.

[0045] like Figure 5As shown, in some embodiments, an impurity trapping cylinder 25 is provided inside the cavity of the filter element 21 of this invention, and the impurity trapping cylinder 25 is positioned above the water inlet 22. After water enters the filter element 21 through the water inlet 22, part of the water flows backward through the filter holes 23, while part of the water is blocked and flows upward along the axial direction of the filter element 21. The upward-flowing water washes down the impurities attached to the inside of the filter element 21 and carries them upward. The impurities flowing upward with the water are trapped by the impurity trapping cylinder 25, while the water continues to flow backward through the holes on the impurity trapping cylinder 25.

[0046] like Figure 5 and Figure 6 As shown, in some embodiments, the impurity trapping cylinder 25 of this invention has an inverted trumpet-shaped structure, with a larger diameter at the bottom and a smaller diameter at the top. This allows impurities to easily enter from the bottom of the impurity trapping cylinder 25 but makes it difficult for them to flow back from the top. A gap is left between the outer surface of the impurity trapping cylinder 25 and the inner wall of the filter element 21, and the trapped impurities are temporarily stored in the gap between the impurity trapping cylinder 25 and the filter element 21. At this time, water will flow back to the main water supply pipe 11 through the filter holes 23 and the holes on the impurity trapping cylinder 25.

[0047] In some embodiments, the upper end of the filter element 21 of this invention is provided with a sealing head 24. The sealing head 24 includes a threaded head that is threadedly connected to the filter element fixing head 13. A nut is provided at the end of the threaded head, and the nut is placed outside the filter element fixing head 13. The filter element 21 is fixed by a threaded connection, thereby allowing the filter element 21 to be easily disassembled and cleaned.

[0048] like Figure 3 As shown, in some embodiments, the inner wall of the main water supply pipe 11 of this invention is provided with an antibacterial coating 15 to inhibit microorganisms in the water. The antibacterial coating 15 can be a silver ion layer. The antibacterial coating 15 has a smooth surface to prevent scale from adhering inside the main water supply pipe 11 and clogging it.

[0049] In summary, the PE water supply pipe with antibacterial filtration function of this utility model filters impurities in the water by setting a branch pipe 12 at an angle on the main water supply pipe 11 and inserting the filter mechanism 2 at an angle from the branch pipe 12 into the main water supply pipe 11. When water flows through the main water supply pipe 11, the water flow will obliquely wash the outer surface of the filter mechanism 2, making it difficult for impurities in the water to adhere to the outer surface of the filter mechanism 2. This achieves the effect of filtering impurities in the water while reducing the clogging of the filter mechanism 2 by impurities.

[0050] This utility model uses a filter mechanism 2 that is inclined in the main water supply pipe 11. When the water flows, it will impact the filter mechanism 2 in an oblique manner. When the main water supply pipe 11 is suddenly connected to or disconnected from water, the impact force generated by the water flow will be dissipated by the inclined filter mechanism 2, avoiding direct impact on the filter mechanism 2. This reduces the impact force of water hammer effect on the filter mechanism 2 and valve, thereby improving the service life.

[0051] This invention provides an impurity trapping cylinder 25 inside the cavity of the filter element 21. When impurities inside the filter element 21 are impacted by water flow, they float upward along the inner radial direction of the filter element 21 and pass through the impurity trapping cylinder 25. As the inner diameter of the impurity trapping cylinder 25 gradually decreases, the impurities are trapped in the gap between the outer surface of the impurity trapping cylinder 25 and the inside of the filter element 21, thereby further preventing impurities from clogging the filter holes 23.

[0052] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0053] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
