In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0027] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0028] For scale inhibitor core assembly, please refer to [link / reference]. Figure 1-3 As shown, it includes: filter cartridge housing 100, scale inhibition unit 200 and suction cup 300.

[0029] The filter housing 100 has an internal mounting cavity 101. The filter housing 100 is provided with a fluid exchange port 102 that connects the mounting cavity 101 to the outside. The scale inhibition unit 200 is installed in the mounting cavity 101.

[0030] The term "external" refers to the space where the scale inhibitor core assembly is installed. For example, if the scale inhibitor core assembly is installed in a water tank, then "external" refers to the space inside the water tank. Water in the water tank flows into the installation cavity 101 through the fluid exchange port 102, and water in the installation cavity 101 flows out to the water tank through the fluid exchange port 102. The scale inhibitor unit 200 can reduce scale and prevent scale from depositing in the water tank.

[0031] The scale inhibitor unit 200 uses commercially available scale inhibitors, and the specific composition and structure are not specified here.

[0032] The suction cup 300 is installed on the filter element housing 100, and the filter element housing 100 is installed on the mounting surface 00 by the suction cup 300. The installation method is simple and quick. Here, the mounting surface 00 refers to the installation position. For example, if it is installed in a water tank, the mounting surface 00 refers to the inner wall surface of the water tank. The suction cup 300 makes the entire scale inhibitor core assembly stably installed in the water tank.

[0033] The suction cup 300 includes a disc portion 310, a neck portion 320, and a top portion 330; the neck portion 320 is located above the disc portion 310, and the top portion 330 is located above the neck portion 320; the filter cartridge housing 100 is provided with a mounting hole 103 for assembling the suction cup 300; the outer diameter of the top portion 330 is larger than the diameter of the mounting hole 103; when the suction cup 300 is assembled into the filter cartridge housing 100, the disc portion 310 is located outside the filter cartridge housing 100, the neck portion 320 passes through the mounting hole 103, and the top portion 330 is located inside the filter cartridge housing 100.

[0034] The disc 310, neck 320, and top 330 can be integrally molded from silicone material and are deformable. During installation, the top 330 is squeezed and deformed to pass through the mounting hole 103 and enter the filter element housing 100. The suction cup 300 is installed in the filter element housing 100 by limiting the top 330. Similarly, during removal, the suction cup 300 is pulled in the opposite direction, and the top 330 is squeezed and deformed to pass through the mounting hole 103 and be pulled out. The entire installation and disassembly process is simple, convenient, and efficient.

[0035] The entire scale inhibitor core assembly is installed on the surface 00 using a suction cup 300. The entire installation and disassembly process is simple, convenient, efficient, and has low replacement costs.

[0036] In one embodiment, the top 330 is provided with an inclined guide surface 331 to guide the top 330 through the mounting hole 103 into the interior of the filter housing 100; as Figure 3 As shown, the guide surface 331 is inclined from bottom to top towards the axis of the suction cup 300, effectively guiding the top 330 upward through the mounting hole 103 into the filter cartridge housing 100; at the same time, the neck 320 is located inside the mounting hole 103; the outer diameter of the neck 320 can be equal to, slightly less than, or slightly larger than the diameter of the mounting hole 103.

[0037] In one embodiment, the disc portion 310 is bowl-shaped, and the disc portion 310, neck 320, and top 330 are coaxially arranged. After the suction cup 300 is installed in the filter element housing 100, the scale inhibitor core assembly is installed as follows: Figure 4 As shown, press down on the scale inhibitor core assembly to expel the air from the bottom of the suction cup 300. The lower wall of the suction cup 300 will then adhere to the installation surface 00, completing the installation. To remove the scale inhibitor core assembly, simply lift the edge of the disc 310 from any position.

[0038] In one embodiment, the top end of the disk portion 310 is provided with a plane 311, and the neck portion 320 is disposed on the plane 311;

[0039] like Figure 3 As shown, the bottom surface of the filter housing 100 is a plane, the top of the disc portion 310 is provided with a plane 311, and the neck 320 is located at the center of the plane 311. When the filter housing 100 is pressed down, the bottom surface of the filter housing 100 contacts the plane 311 better, and the disc portion 310 is pressed down more effectively, so that the suction cup 300 is adsorbed on the mounting surface 00.

[0040] In one embodiment, the filter housing 100 includes an upper housing 110 and a lower housing 120 combined together, wherein the upper housing 110 and / or the lower housing 120 are provided with a fluid exchange port 102.

[0041] Here, the filter housing 100 adopts a combination of upper housing 110 and lower housing 120, which makes it easier to install the scale inhibition unit 200;

[0042] In practice, only the upper housing 110 may have a fluid exchange port 102, while the lower housing 120 may not have a fluid exchange port 102.

[0043] Alternatively, the fluid exchange port 102 may be provided only in the lower housing 120, while the upper housing 110 may not have a fluid exchange port 102.

[0044] Alternatively, fluid exchange ports 102 can be provided in both the upper housing 110 and the lower housing 120;

[0045] All three methods described above can achieve fluid exchange between the inside and outside of the mounting cavity 101.

[0046] Furthermore, a sleeve 122 extending from the inner wall of the lower housing 120 toward the upper housing 110 is provided at the center of the lower housing 120, and the sleeve 122 is integrally formed on the lower housing 120.

[0047] The sleeve 122 divides the mounting cavity 101 into an inner chamber 1011 and an outer chamber 1012, and the scale inhibition unit 200 is installed in the outer chamber 1012; the mounting hole 103 is provided on the bottom surface of the lower housing 120 and communicates with the inner chamber 1011.

[0048] The inner chamber 1011 and the outer chamber 1012 can be connected or disconnected; the scale inhibition unit 200 is installed in the outer chamber 1012, and the top 330 of the suction cup 300 enters the inner chamber 1011 without affecting the installation of the scale inhibition unit 200.

[0049] Optionally, if a scale inhibition unit is also placed inside the inner chamber 1011, then a fluid exchange port needs to be provided in the sleeve 122 to further realize the communication between the inner chamber 1011 and the outside.

[0050] The scale inhibition units placed in the inner chamber 1011 and the outer chamber 1012 can be the same or different.

[0051] In one embodiment, the filter cartridge 100 is cylindrical, and the top surface of the upper housing 110 is provided with a fluid exchange port 102; the side and bottom surfaces of the lower housing 120 are also provided with fluid exchange ports 102.

[0052] like Figure 2 As shown, the top surface of the upper housing 110 is provided with a plurality of fluid exchange ports 102, which are roughly distributed on the top of the outer chamber 1012; the sides and bottom surfaces of the lower housing 120 are also provided with a plurality of fluid exchange ports 102, which can effectively promote fluid exchange between the mounting cavity 101 and the outside.

[0053] Furthermore, the upper housing 110 and the lower housing 120 are connected by a combination of threaded connection, snap-fit ​​connection, and rotary connection;

[0054] If a threaded connection is used, an internal thread can be provided on the upper housing 110 and an external thread can be provided on the upper part of the lower housing 120 to achieve a threaded combination;

[0055] If connected by snap-fit, such as Figure 2 As shown, a buckle groove 111 can be provided in the upper housing 110 and a buckle part 121 can be provided in the lower housing 120 to realize a buckle assembly; in this embodiment, the upper housing 110 and the lower housing 120 adopt a buckle combination method.

[0056] Alternatively, if a screw fastening method is used, a screw fastening groove can be provided in the upper housing 110 and a screw fastening part can be provided in the lower housing 120 to realize a screw fastening assembly.

[0057] In all three of the above combinations, the upper housing 110 and the lower housing 120 can be disassembled and assembled in a simple and quick manner. The upper housing 110, the lower housing 120 and the suction cup 300 can all be disassembled, enabling quick assembly and disassembly. Each component is easy to clean after disassembly, and easy to replace if a component is damaged. The entire scale inhibitor core assembly is small in size after assembly.

[0058] An ice maker, such as Figure 4 As shown, the device has a body with a water tank 400, in which the aforementioned scale inhibitor core assembly is installed. The scale inhibitor core assembly is easy to install and remove; it can be attached to the inner bottom wall of the water tank 400 by suction cup 300, i.e., the inner bottom wall of the water tank 400 forms the aforementioned mounting surface 00. After a period of use, the scale inhibitor core assembly can be easily removed for cleaning or replacement.

[0059] Figure 4 The scale inhibitor core assembly is simply placed in the water tank 400. It is necessary to apply force to press down on the scale inhibitor core assembly so that the suction cup 300 is pressed down and deformed and attracted to the mounting surface 00, so that the scale inhibitor core assembly is fixed.

[0060] In addition to ice makers, the aforementioned scale inhibitor core components can also be used in other devices with water tanks or reservoirs.
