Referring to fig. 1, the present embodiment provides a filter element assembly 1, which includes a housing 100 and a filter element 200 accommodated in the housing 100. It will be understood by those skilled in the art that the housing 100 has a structure conventional in the art for a cartridge assembly housing for connecting the cartridge assembly 1 to a conventional filter assembly or other cartridge assembly. For example, the housing 100 is provided with a water inlet 101, a water outlet 102 and a concentrated water outlet 103 for guiding raw water without being filtered into the filter element assembly 1 for filtering, and discharging concentrated water and filtered purified water generated by filtering. In addition, the housing 100 may also have other structures known in the art, such as, but not limited to: the housing 100 may also include an end cap 110 for sealing the housing 100 and placing the filter cartridge 200.

In this embodiment, the filter cartridge 200 is disposed in the cavity 100a of the housing 100, and may be a reverse osmosis membrane filter cartridge (RO cartridge) having a conventional structure, including a central water collecting pipe 201 and a filter membrane 202 disposed around the central water collecting pipe 201, as shown in fig. 2. The central collection pipe 201 and the filter membrane 202 are of conventional construction of reverse osmosis membrane cartridges known in the art.

In addition, the filter element assembly 1 of the present embodiment has other conventional structures that are known to be included in the filter element assembly, for example, but not limited to, as shown in fig. 1 and fig. 2, the filter element assembly 1 may further include: a connecting end cap 210 for connecting the filter cartridge 200 to the housing 100, and a fixing ring 220 for fixing the filter membrane 202. As shown in fig. 2, the connection end cap 210 is hermetically connected to the water inlet 101, the water outlet 102 and the concentrated water outlet 103 of the housing 100. The fixing ring 220 may be a conventional fixing ring structure, and only has a fixing function, and is not related to the technical effect to be achieved by the present application, so that the present application does not intend to limit the structure of the fixing ring 220 as long as the conventional fixing ring structure can perform the fixing function.

As shown in fig. 1 and 2, in the filter cartridge module 1 of the present application, at least one fixing member 230 is provided on an outer circumferential surface of the filter cartridge 200, particularly, on an outer circumferential surface of the filter membrane 202 of the filter cartridge 200, for placing the scale inhibitor 300 as shown in fig. 3.

In addition, the fixing member 230 may have a ring shape as shown in fig. 1 to cover an annular portion of the outer circumferential surface of the filter cartridge 200; it will be appreciated by those skilled in the art that the securing assembly 230 may also be part-annular, i.e., the securing assembly 230 may be a part-annular structure to cover a portion of the annular portion of the outer peripheral surface of the cartridge 200.

Furthermore, as shown in fig. 1 and 2, a fixing assembly 230 is disposed on the outer peripheral surface of the filter element 200, especially on the outer peripheral surface of the filter membrane 202 of the filter element 200, and a plurality of fixing assemblies can be disposed according to actual needs by those skilled in the art, and these different technical solutions also fall within the scope of the present application.

As shown in fig. 3, the fixing assembly 230 has a receiving space 230a for placing the scale inhibitor 300. The shape and structure of the accommodating space 230a are not limited to the structure shown in fig. 3. In the present embodiment, the fixing member 230 includes a first sidewall 231 and a second sidewall 232. As shown in fig. 3, an edge of the first sidewall 231 is hermetically connected with an edge of the second sidewall 232 to form the accommodating space 230 a. The sidewall that is in contact with the outer circumferential surface of the filter cartridge 200 is defined as the first sidewall 231.

In order to allow the scale inhibitor 300 disposed in the accommodating space 230a to be slowly released through the fixing member 230, at least one of the first sidewall 231 and the second sidewall 232 has a porous structure. Specifically, the first sidewall 231 for contacting the outer circumferential surface of the filter cartridge 200 may have no porous structure or a porous structure; and the second sidewall 232 may have a porous structure.

In addition, it can be understood by those skilled in the art that all of the first side wall 231 and the second side wall 232 may not be porous, but only have a porous structure at a portion forming the accommodating space 230a, so that the scale inhibitor 300 placed in the accommodating space can be slowly released through the fixing member 230. For example, as shown in fig. 3, the second sidewall 232 is divided into: a connection portion 232a hermetically connected to the first sidewall 231, and a contact portion 232b forming the receiving space 230 a. As an embodiment, the connection portion 232a and the contact portion 232b of the second sidewall 232 have a porous structure, so that the scale inhibitor 300 placed in the accommodating space 230a can be slowly released through the fixing member 230. As another embodiment, only the contact portion 232b of the second sidewall 232 has a porous structure, so that the scale inhibitor 300 placed in the accommodating space 230a can be slowly released through the fixing member 230. Of course, as another embodiment, only a part of the contact portion 232b of the second sidewall 232 has a porous structure, that is, the contact portion 232b does not necessarily have to be a porous structure in its entirety, but only a part of the area is required to be a porous structure.

In addition, in order to allow the scale inhibitor 300 to be soaked with sufficient moisture to increase the usage rate of the scale inhibitor, as shown in fig. 2 and 3, a gap is provided between the fixing member 230 (particularly, the second sidewall 232 of the fixing member 230) and the inner circumferential surface of the housing 100. Thus, the scale inhibitor 300 can be soaked with sufficient moisture to achieve sustained release through the gaps and the porous structure.

In addition, it will be understood by those skilled in the art that the material of the first sidewall 231 and the second sidewall 232 is not particularly required, and any rigid material suitable for water filter assembly, such as polypropylene, etc., may be any flexible material suitable for water filter assembly, such as rubber, fabric, etc. Also, the material of the first sidewall 231 and the second sidewall 232 need not be the same, for example, the material of the first sidewall 231 is a rigid material and the material of the second sidewall 232 is a flexible material, or vice versa. In one embodiment, the first side wall 231 and the second side wall 232 are both made of fabric, especially cloth suitable for water filtering components, so that the fixing component 230 is a mesh bag or a cloth bag.

In addition, it will be understood by those skilled in the art that the antisludging agent 300 may be any known antisludging agent for water filter assemblies known in the art, and is used to control the inorganic salt from scaling on the outer surface of the filter element 200 (especially, the filter membrane 202) so as to solve the problem of the reduction of the service life of the filter element 200 due to scaling. It will be understood by those skilled in the art that different formulations or compositions of the scale inhibitor 300 may be used for different filter elements 200, such as but not limited to hypophosphite, FOF scale inhibitor, etc. The application is not intended to limit the type and composition of the scale inhibitor as long as its function is achieved.

From this, filter element group spare 1 in, through fixed subassembly 230's setting, with antisludging agent 300 rationally attached in the filter membrane 202 surface, both solved the space problem that antisludging agent 300 placed, make simultaneously again antisludging agent 300 has sufficient moisture to soak, has promoted antisludging agent 300's rate of utilization by a wide margin.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
