[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0030] Please refer to Figure 1-7 ;

[0031] The new composite membrane shell has most of the parts integrally injection-molded on the end cover and the outer jacket, which greatly reduces the parts that need to be installed and facilitates the disassembly, assembly and maintenance of the water treatment components.

[0032] Specifically, it includes a shell 1 and a filter element 2. The outer shapes of the shell 1 and the filter element 2 of the utility model are both circular. The outer wall of the shell 1 is made of glass fiber. Since the glass fiber has the characteristics of corrosion resistance, high strength, light weight and easy molding, it can reliably protect the internal water treatment equipment for a long time. The filter element 2 is arranged inside the shell 1. The shell 1 is used to prevent dust from invading, which causes the water treatment effect of the filter element 2 to deteriorate, thereby improving the service life of the filter element 2. Mounting parts 3 are provided at both ends of the filter element 2. The center of the mounting part 3 is provided with a through hole 21 corresponding to the through hole 1. The through hole 21 and the through hole 2 The apertures of the through holes 31 are the same, and an output pipe 32 is installed on the through hole 21. The water filtered by the filter element 2 will gather in the through hole 1 21, and then flow from the through hole 1 21 to the output pipe 32. The two ends of the shell 1 are threadedly connected with the outer sleeve 4. The outer wall of the shell 1 is provided with an external thread, and the inner wall of the outer sleeve 4 is provided with an internal thread. The external thread of the shell 1 is threadedly connected with the internal thread of the outer sleeve 4. The inner part of the outer sleeve 4 is rotatably connected with an end cap 5 through a clamping part. The shell and the end cap are made of plastic material. A first annular groove 6 is provided between the end cap 5 and the outer sleeve 4. The bottom of the first annular groove 6 abuts against the end of the shell 1 to form The sealing structure prevents water from leaking from the connection. The end cover 5 is provided with a water outlet 53 connected to the output pipe 32. The output pipe 32 is partially installed inside the water outlet 53. After the water is introduced, the water level inside the shell 1 will rise. When it rises to the position of the output pipe 32, the water will flow out from the output pipe 32. A water inlet 52 is provided on one side of the water outlet 53 for introducing the water to be filtered. The end cover 5 is provided with an inclined surface. When the outer shell 4 and the end cover 5 are installed in the outer shell 1, the inclined surface abuts against the outer shell 1 to form a sealing structure 7 to further prevent water from leaking. The clamping part includes a plurality of clamping parts 41 arranged on the inner side of the outer shell 4. And a clamping piece 55 is arranged on the outside of the end cover 5 and is rotatably clamped with a plurality of clamping pieces 41. The clamping piece 41 and the clamping piece 55 are staggered and clamped. The outer shapes of the clamping piece 41 and the clamping piece 55 of the utility model are both triangular. When the existing membrane shell is installed, the winding layer is first thickened, and the length is fixed each time, and the two ends are subsequently processed. However, this production is too troublesome, inefficient, and costly. The membrane shell of the utility model is characterized by the use of plastic parts with internal threads at both ends. The plastic parts are threadedly connected to the membrane shell through threads, and the plastic parts can be molded by one injection molding, which has higher production efficiency and lower cost.

[0033] Specifically, a gap is left between the two clip parts 41, and a gap is also left between the two clip parts 55. The clip part 41 is inserted into the gap between the clip parts 55, and the clip part 55 is inserted into the gap between the clip parts 41, so that the side of the clip part 41 abuts against the side of the clip part 2 55, completing the fixed connection between the end cover 5 and the outer sleeve 4. This special tooth design makes disassembly and assembly more convenient. The filter element 2 is installed into the inside of the outer shell 1, and the mounting parts 3 are assembled on both sides of one end of the through hole on the filter element 2, and the output pipe 32 is inserted into the through hole 31 of the mounting part 3. Finally, the outer sleeve 4 is tightly connected to the outer shell 1 by threading, and the output pipe 32 is accurately connected to the water outlet 53 to ensure the stability of water supply. The fixed installation of the water treatment membrane shell can be completed. By integrally injection molding most of the parts on the end cover and the outer sleeve, the parts that need to be installed are greatly reduced, which facilitates the disassembly, assembly and maintenance of the water treatment components.

[0034] In this embodiment, there are 16 clips 41, each group of 4, each group of clips 41 are arranged vertically and arranged in a 90° circular array, and a sliding portion 42 is provided between every two groups of clips 41, and the sliding portion 42 can be used for the insertion of the clip 2 55.

[0035] Furthermore, there are also 16 clips 55, each 4 forming a group, and each group of clips 41 are arranged vertically and in a 90° circular array, and a sliding portion 56 is provided between every two groups of clips 55, and the sliding portion 56 can be used for the clips 41 to be inserted, wherein two groups of symmetrically arranged clips 55 are provided with a baffle 57 on one side, and the baffle 57 is used to limit the rotation angle of the end cover 5.

[0036] In the above embodiment, when the second clip 55 is aligned with the sliding part 42, the second clip 41 will also be aligned with the sliding part 56. By aligning the second clip 55 with the sliding part 42 for insertion, the second clip 55 will also be inserted along the sliding part 42. After the insertion is completed, the end cover 5 is rotated so that the second clip 41 and the second clip 55 are staggered and engaged, and the installation of the end cover 5 and the sleeve 4 is completed.

[0037] In this embodiment, the end cap 5 is provided with a protruding ring 54 that abuts against the bottom of the outer sleeve 4, which is used to limit the insertion depth of the end cap 5. When inserting, the end cap 5 is directly inserted until the protruding ring 54 abuts against the bottom of the outer sleeve 4, and then the end cap 5 can be rotated to fix the end cap 5 and the outer sleeve 4.

[0038] In this embodiment, the outer wall of the end cover 5 is provided with a second annular groove 51 for installing a seal. The seal abuts against the inner wall of the housing 1 to form a seal to prevent water from flowing out of the gap and improve the sealing effect. The seal can be a rubber ring.

[0039] In this embodiment, the filter element 2 includes an external filter layer, an activated carbon layer is provided inside the external filter layer, and the through hole 1 21 is located at the center of the activated carbon layer.

[0040] Specifically, the external filter layer serves to block large particles of impurities and suspended matter, effectively protecting the subsequent filter layer from clogging and extending the overall service life of the filter element 2, while the activated carbon filter layer is mainly filled with granular activated carbon. The activated carbon has beneficial effects such as adsorbing residual chlorine and other organic pollutants, removing heavy metal ions, and improving water quality. The water to be filtered is filtered through the activated carbon, and the water flows out from the through hole 1 21 after filtration is completed.

[0041] In this embodiment, the water inlet 52 and the water outlet 53 are both provided with internal threads.

[0042] Specifically, the setting of the internal thread allows the connected pipes and water outlet equipment to be disassembled and installed by simple rotation, and the connection is tight enough to avoid water leakage and waste, thereby ensuring the stability of the connection.
