Reverse osmosis water purifiers can provide people with healthy and safe water through terminal purification, and are becoming more and more popular in people's daily lives.

[0003] The core processing unit of the water purifier product is the reverse osmosis membrane, which is generally made into a roll-type membrane structure according to the actual needs of use. The reverse osmosis membrane is often placed in a component called a membrane shell. The bottom of the membrane shell is provided with a clean water discharge port and a concentrated water discharge port, and the top is provided with a membrane shell cover, which is provided with a tap water inlet. The raw water enters the reverse osmosis membrane shell through the tap water inlet, and after being filtered by the reverse osmosis membrane, a part of it becomes pure water and is discharged from the clean water discharge port, and a part of it becomes waste water and is discharged from the concentrated water discharge port.

[0004] In water purifier products, multiple groups of reverse osmosis membranes are usually used, that is, multiple groups of membrane shells are connected together by water pipes. The current practice is to install joints at the tap water inlet, concentrated water discharge port and clean water discharge port of the artificial membrane shell, and then connect the corresponding tap water inlet, corresponding concentrated water discharge port and corresponding clean water discharge port on the two adjacent membrane shells through water pipes. This method has high labor intensity and low installation efficiency. Utility Model Content

[0037] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0038] The principle and spirit of the present invention are explained in detail below with reference to several representative embodiments of the present invention.

[0039] Embodiment 1 of the injection-molded reverse osmosis membrane shell provided by the utility model:

[0040] like Figure 1 and Figure 2 As shown, the injection molded reverse osmosis membrane shell includes a shell 1 and a membrane cover 2 threadedly connected to the shell 1. Figure 5 As shown, the membrane cover 2 includes a cover body and a water inlet pipe 5 and a first pure water pipe 3 integrally injection-molded on the cover body. Figure 3 and Figure 4 As shown, the water inlet pipe 5 and the first pure water pipe 3 are parallel and separated from each other, and the water inlet pipe 5 and the first pure water pipe 3 are partially buried in the cover body, and the depth of the buried in the cover body is half of the pipe diameter of the water inlet pipe 5 and half of the pipe diameter of the first pure water pipe 3 respectively; the bottom end of the shell 1 is integrally injection-molded with the drain pipe 6 and the second pure water pipe 4, the drain pipe 6 and the second pure water pipe 4 are parallel and separated from each other, and the drain pipe 6 and the second pure water pipe 4 are partially buried in the shell, and the depth of the buried in the shell is half of the pipe diameter of the drain pipe 6 and half of the pipe diameter of the second pure water pipe 4 respectively, so that mass production can be achieved through injection molds. Of course, the above-mentioned buried depth is not limited to half of the corresponding pipe diameter, as long as injection molding can be achieved.

[0041] like Figure 3 and Figure 4As shown, the axes of the water inlet pipe 5, the drain pipe 6, the first pure water pipe 3 and the second pure water pipe 4 are all perpendicular to the axis of the housing 1. The first pure water pipe 3 is integrally injection molded with a first filter element interface 7 for installing a reverse osmosis membrane filter element, and the second pure water pipe 4 is integrally injection molded with a second filter element interface 8 for installing a reverse osmosis membrane filter element. The first filter element interface 7 and the second filter element interface 8 are both coaxially arranged with the housing 1. The first filter element interface 7 is connected to the first pure water pipe 3, the second filter element interface 8 is connected to the second pure water pipe 4, and the water inlet pipe 5 and the drain pipe 6 are both connected to the inner cavity of the housing 1. A plurality of reinforcing support ribs 15 uniformly arranged along the circumferential direction of the filter element interface are integrally molded between the first filter element interface 7 and the inner wall of the housing 1, and between the second filter element interface 8 and the inner wall of the housing 1. The second filter element interface 8 extends to the outside of the housing 1 in the form of a tube. For injection molding requirements, when in use, the end of the second filter element interface 8 away from the first filter element interface 7 is in a blocked state.

[0042] In this embodiment, the diameter of the water inlet pipe 5 is the same as that of the drain pipe 6, and the diameter of the first pure water pipe 3 is the same as that of the second pure water pipe 4. The diameter of the water inlet pipe 5 is larger than that of the first pure water pipe 3. The projections of the water inlet pipe 5 and the drain pipe 6 in the vertical direction overlap, and the projections of the first pure water pipe 3 and the second pure water pipe 4 in the vertical direction overlap, and the appearance is neat.

[0043] The corresponding ends of the water inlet pipe 5, the drain pipe 6, the first pure water pipe 3 and the second pure water pipe 4 are all provided with a limit stop edge 10, and the water inlet pipe 5, the drain pipe 6, the first pure water pipe 3 and the second pure water pipe 4 are all provided with a plurality of annular sealing grooves 9 on the circumference thereof, and the annular sealing grooves 9 are used to install a sealing ring 16, such as Fig.10 shown.

[0044] In actual use, both ends of the first pure water pipe 3 are blocked, and pure water flows out from the second pure water pipe 4. Of course, in actual use, the drain pipe 6 can also be set on the membrane cover 2, and the water inlet pipe 5 can be set at the bottom end of the shell 1.

[0045] The reverse osmosis membrane shell of the utility model is injection molded, and compared with the existing stainless steel membrane shell, the overall weight is light, and the water inlet pipe 5, the drain pipe 6, the first pure water pipe 3 and the second pure water pipe 4 are injection molded and integrated on the reverse osmosis membrane shell. In this way, during assembly, the installer can save the steps of installing the joints and the water inlet pipe 5, the drain pipe 6, the first pure water pipe 3 and the second pure water pipe 4. It is only necessary to connect the corresponding water inlet pipe 5, the drain pipe 6, the first pure water pipe 3 and the second pure water pipe 4 on the two reverse osmosis membrane shells that need to be connected, thereby saving installation time and improving installation efficiency.

[0046] Embodiment 2 of the injection-molded reverse osmosis membrane shell provided by the utility model:

[0047] The main difference between it and Example 1 is that in Example 1, the diameters of the first pure water pipe 3 and the second pure water pipe 4 are smaller than the diameters of the water inlet pipe 5 and the drain pipe 6. In this embodiment, the diameters of the first pure water pipe 3 and the second pure water pipe 4 are equal to the diameters of the water inlet pipe 5 and the drain pipe 6. Of course, in other embodiments, the diameters of the first pure water pipe 3 and the second pure water pipe 4 may also be larger than the diameters of the water inlet pipe 5 and the drain pipe 6.

[0048] Embodiment 3 of the injection-molded reverse osmosis membrane shell provided by the utility model:

[0049] The main difference between it and embodiment 1 is that in embodiment 1, the projections of the water inlet pipe 5 and the drain pipe 6 in the vertical direction overlap, and the projections of the first pure water pipe 3 and the second pure water pipe 4 in the vertical direction overlap. In this embodiment, the projections of the water inlet pipe 5 and the drain pipe 6 in the vertical direction are staggered or partially overlapped, and the projections of the first pure water pipe 3 and the second pure water pipe 4 in the vertical direction are staggered or partially overlapped.

[0050] Specific embodiment of the quick-connect reverse osmosis membrane shell group of the utility model:

[0051] like Figure 6 As shown, the quick-connect reverse osmosis membrane shell group includes a plurality of injection-molded reverse osmosis membrane shells connected in parallel. The structure of the reverse osmosis membrane shell is the same as that of the various embodiments of the injection-molded reverse osmosis membrane shells mentioned above, and will not be described in detail here.

[0052] In this embodiment, the quick-connect reverse osmosis membrane shell group includes four reverse osmosis membrane shells connected in parallel. Of course, the number of reverse osmosis membrane shells can be reasonably set according to needs and is not limited to four in this application. This embodiment focuses on describing how two adjacent reverse osmosis membrane shells are connected.

[0053] Specifically, the corresponding water inlet pipes 5, the corresponding drainage pipes 6, the corresponding first pure water pipes 3 and the corresponding second pure water pipes 4 on two adjacent reverse osmosis membrane shells are all connected by a sealing sleeve 14, and a pipe clamp 11 is provided outside the socket position for fastening.

[0054] The corresponding ends of the water inlet pipe 5, the drain pipe 6, the first pure water pipe 3 and the second pure water pipe 4 are provided with the limit stop edge 10, which cooperates with the corresponding stop of the sealing sleeve 14 to position the sealing sleeve 14. The sealing sleeve 14 is used to realize the socket connection of the corresponding two pipes. The pipe clamp 11 is arranged outside the sealing sleeve 14, and the pipe clamp 11 includes two clamp bodies, each of which is provided with a first pipe groove 12 adapted to the water inlet pipe 5 and the drain pipe 6, and a second pipe groove 13 adapted to the first pure water pipe 3 and the second pure water pipe 4. The two clamp bodies are fastened and connected by a bolt and nut assembly, thereby fastening the connection part of the two adjacent reverse osmosis membrane shells to ensure the sealing effect.

[0055] When assembling the quick-connect reverse osmosis membrane shell group of the present invention, it is only necessary to connect the two corresponding water inlet pipes 5, the two corresponding drainage pipes 6, the two corresponding first pure water pipes 3 and the two corresponding second pure water pipes 4 on the two adjacent reverse osmosis membrane shells through the sealing sleeve 14, and then tighten them with the pipe clamp 11 at the plug-in position. The installation is convenient, saving the workers' installation time and improving the installation efficiency.

[0056] According to the above description of this specification, those skilled in the art may also understand that the terms used below, such as "upper", "lower", "circumferential", etc., which indicate orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings of this specification, and are only for the purpose of facilitating the explanation of the scheme of the utility model and simplifying the description, rather than explicitly or implicitly indicating that the device or element involved must have the specific orientation, be constructed and operated in a specific orientation. Therefore, the above-mentioned orientation or positional relationship terms cannot be understood or interpreted as limitations on the scheme of the utility model.

[0057] In addition, in the description of this specification, “plurality” means at least two, for example, two, three or more, etc., unless otherwise clearly and specifically defined.
