[0036] Overall, the installation device achieves the connection and fixation between the socket assembly 2 and the shell 1 by connecting the socket assembly 2 with the second opening 12 of the shell 1; during assembly, only need to insert the filter core assembly 3 into the cavity along the first opening 11 and reach the preset position, to achieve the sleeve connection of the tubular structure 31 with the water inlet and outlet pipeline 21, that is, the sleeve connection of the filter core assembly 3 with the socket assembly 2 is realized during the insertion of the filter core assembly 3, which simplifies the connection operation; then use the connecting structure 32 to realize the connection and fixation between the shell 1 and the filter core assembly 3; during disassembly, only need to release the connection between the connecting structure 32 and the shell 1, to take down the entire filter core assembly 3, greatly simplifying the disassembly operation, not only improving the production efficiency, but also bringing convenience for users to disassemble and replace the filter core assembly 3.

[0037] It should be noted that, since the shell 1 and the socket assembly 2 do not need to be frequently installed and disassembled, the shell 1 and the socket assembly can adopt a detachable connection mode, or a non-detachable connection such as welding. As an optional embodiment, a through hole is provided on the socket assembly 2, and a threaded hole is provided at the opening of the second opening 12 of the shell 1, and a threaded connecting piece passes through the through hole and is screwed with the threaded hole, thereby realizing the detachable connection between the shell 1 and the socket assembly 2.

[0039] To address the issue of simplifying the connection operation between the connecting structure 32 and the first opening 11, in this embodiment of the invention, the connecting structure 32 is rotatably connected to the bottom of the filter element assembly 3. The connecting structure 32 is annular, and its outer periphery has a protrusion 321. The first opening 11 is provided with a first guide structure 111 extending circumferentially, and the end of the first guide structure 111 extending circumferentially is provided with a snap-fit ​​groove 112. After the filter element assembly 3 reaches a preset position, the protrusion 321 is used to rotate along the first guide structure 111 to a preset angle so that the protrusion 321 snaps into the snap-fit ​​groove 112.

[0040] In the above structure, by rotatably connecting the connecting structure 32 to the bottom of the filter element assembly 3, the connecting structure 32 can rotate axially relative to the filter element assembly 3. Furthermore, by having a protrusion 321 on the outer periphery of the connecting structure 32 and a first guide structure 111 extending circumferentially in the first opening 11, after the filter element assembly 3 reaches a preset position, rotating the connecting structure 32 causes the protrusion 321 to rotate along the first guide structure 111. Additionally, by having a locking groove 112 at the circumferentially extending end of the first guide structure 111, the protrusion 321 can engage with the locking groove 112 after rotating to a preset angle, thus achieving the connection between the connecting structure 32 and the first opening 11. This connection operation is simple and quick; simply rotating the connecting structure 32 to a preset angle is sufficient to engage the protrusion 321 with the locking groove 112. Disassembly is also simple, requiring only a reverse rotation in the original direction of rotation, thereby simplifying the connection operation between the connecting structure 32 and the first opening 11. In one optional implementation, the bottom of the filter element assembly 3 and the top of the connecting structure 32 are provided with through holes. Screws and other threaded fasteners pass through the through holes of the connecting structure 32 and the filter element assembly 3, and nuts are used to engage with the threaded fasteners, so that the filter element assembly 3 and the connecting structure 32 are connected to each other while still retaining a certain degree of rotational freedom.

[0041] To address the problem that the connecting structure 32 is difficult to hold and rotate, in this embodiment of the invention, a holding structure 33 is provided at the bottom of the connecting structure 32, and the holding structure 33 extends in the direction away from the filter element assembly 3.

[0042] In the above structure, by providing a gripping structure 33 at the bottom of the connecting structure 32 and extending the gripping structure 33 in the direction away from the filter element assembly 3, the gripping structure 33 provides an effective force application point for the user, making it easy for the user to rotate the connecting structure 32 by twisting the gripping structure 33, so as to achieve the snap-fit ​​between the connecting structure 32 and the snap-fit ​​groove 112.

[0043] To address the problem of separating unfiltered external water from filtered water, in this embodiment of the invention, the tubular structure 31 has two independent pipe fittings 311, which are internally connected to the filter element assembly 3; the inlet and outlet water pipes 21 have two independent pipe structures, each including a first pipe section 211, a second pipe section 212, and a connecting port 213, with the first pipe section 211 connected to the second pipe section 212 via the connecting port 213; the second pipe section 212 of the two pipe structures is used to correspondingly fit around the outer periphery of the two pipe fittings 311; one pipe structure is used to supply external water to the filter element assembly 3, and the other pipe structure is used to receive filtered water from the filter element assembly 3.

[0044] In the above structure, by having the tubular structure 31 have two independent pipe fittings 311 and the inlet and outlet water pipes 21 have two independent pipe structures, the second pipe sections 212 of the two pipe structures are correspondingly sleeved with the outer peripheries of the two pipe fittings 311; in this way, one pipe structure can be used to introduce an external water source into the filter element assembly 3, and the other pipe structure can be used to receive the filtered water from the filter element assembly 3, thereby achieving the separation of different water bodies and avoiding the external water source from polluting the filtered water.

[0045] To address the issue that the connector assembly 2 cannot automatically stop water flow when the filter element assembly 3 is not properly assembled or disassembled, in this embodiment of the invention, a water-stop valve 214 and an elastic element 215 are provided within the pipeline structure. The elastic element 215 and the water-stop valve 214 are located within the first pipe section 211. One side of the elastic element 215 is connected to the side wall of the first pipe section 211, and the other side of the elastic element 215 abuts against the water-stop valve 214. The elastic element 215 is used to apply force to the water-stop valve 214 so that the water-stop valve 214 abuts against the connecting port 213 and forms a sealing fit. After the filter element assembly 3 reaches the preset position, the tubular structure 31 extends into the second pipe section 212 and presses against the water-stop valve 214 so that the water-stop valve 214 separates from the connecting port 213.

[0046] In the above structure, a water-stop valve 214 and an elastic element 215 are provided within the pipeline structure. The elastic element 215 applies force to the water-stop valve 214, automatically causing the water-stop valve 214 to abut against the connection port 213 and form a sealing fit when the filter element assembly 3 is not assembled or disassembled, preventing water from flowing out of the inlet and outlet pipes 21 and wasting water resources. After the filter element assembly 3 reaches the preset position, the tubular structure 31 extends into the second pipe section 212 and presses against the water-stop valve 214, thereby separating the water-stop valve 214 from the connection port 213, and restoring the connection between the first pipe section 211 and the second pipe section 212. This achieves the effect of automatically connecting the pipeline after the filter element assembly 3 is assembled. This water-stopping method utilizes the elastic force of the elastic element 215 to achieve automatic water stoppage when the filter element assembly 3 is not assembled or disassembled, and automatic pipeline connection after the filter element assembly 3 is assembled. It eliminates the need for users to manually turn on or off the external water source, reducing the need for manual operation.

[0047] Further, in an embodiment of this utility model, the first pipe segment 211 extends laterally, and the second pipe segment 212 extends vertically; the stop valve 214 includes a first rod 2141, an annular protrusion 2142, and a second rod 2143 connected in sequence. The first rod 2141 and the annular protrusion 2142 are disposed inside the first pipe segment 211, and the second rod 2143 passes through the connecting port 213 and extends into the second pipe segment 212; the outer diameter of the annular protrusion 2142 is larger than the outer diameter of the first rod 2141; the elastic member 215 is tubular and is sleeved on the outer periphery of the first rod 2141, with the first pipe segment 211 facing away from the second pipe segment. One end of 212 is connected to one side of the elastic member 215, and the other side of the elastic member 215 abuts against the annular protrusion 2142; the elastic member 215 is used to apply force to the annular protrusion 2142 so that the annular protrusion 2142 abuts against the connecting port 213 and forms a sealing fit; the top of the pipe 311 is provided with an inclined structure 312, which is inclined downward towards the direction of the second rod 2143; the inclined structure 312 is used to move vertically and press against the second rod 2143 so that the second rod 2143 moves laterally and drives the annular protrusion 2142, thereby separating the annular protrusion 2142 from the connecting port 213.

[0048] In the above structure, by placing the first rod 2141 and the annular protrusion 2142 inside the first pipe section 211, the annular protrusion 2142 abuts against the connecting port 213 under the pressure of the elastic member 215 and forms a sealing fit; while the second rod 2143 passes through the connecting port 213 and extends into the second pipe section 212, and the top of the pipe 311 is provided with an inclined structure 312, so that the inclined structure 312 extending into the second pipe section 212 can press against the second rod 2143, so that the second rod 2143 drives the annular protrusion 2142, thereby achieving the effect of separating the annular protrusion 2142 from the connecting port 213. Furthermore, by extending the first pipe segment 211 laterally and the second pipe segment 212 vertically, and by setting the inclined structure 312 downwards toward the second rod 2143, the inclined structure 312, which moves vertically, can apply an oblique force to the second rod 2143 when pressing against it. The oblique force has a first component in the vertical direction and a second component in the horizontal direction, so that the second rod 2143 has both horizontal and vertical motion components. Since the diameter of the connecting port 213 is limited, the second rod 2143 mainly moves laterally, thereby converting the vertical movement of the inclined structure 312 into the horizontal movement of the second rod 2143, so that the annular protrusion 2142 separates from the connecting port 213.

[0049] To address the issue of the annular protrusion 2142 deviating from its moving direction, thus preventing it from fully contacting and sealing with the connecting port 213, in this embodiment of the invention, a sealing structure 216 is provided at the end of the first pipe segment 211 facing away from the second pipe segment 212. A second guide structure 217 is provided on the sealing structure 216. The second guide structure 217 is tubular and extends laterally, and is sleeved on the outer periphery of the first rod 2141. An elastic member 215 is sleeved on the outer periphery of the second guide structure 217 and the first rod 2141, and the end of the elastic member 215 facing the sealing structure 216 is connected to the second guide structure 217. A third opening 2111 is provided on the outer periphery of the first pipe segment 211.

[0050] In the above structure, a sealing structure 216 is provided at the end of the first pipe section 211 facing away from the second pipe section 212. A second guide structure 217 is provided on the sealing structure 216, and the second guide structure 217 is fitted around the outer periphery of the first rod 2141. This restricts the degree of freedom of movement of the first rod 2141, ensuring that the first rod 2141, the connected annular protrusion 2142, and the second rod 2143 can only move laterally. This ensures that the movement direction of the annular protrusion 2142 will not deviate, and that the annular protrusion 2142 can fully abut and seal with the connecting port 213. In addition, after the sealing structure 216 is provided at the end of the first pipe section 211 facing away from the second pipe section 212, a third opening 2111 is provided on the outer periphery of the first pipe section 211, thereby allowing water to enter and exit the first pipe section 211 normally and preventing the sealing structure 216 from completely sealing the first pipe section 211.

[0051] To solve the problem of how the annular protrusion 2142 can form a sealed fit with the connecting port 213, in the embodiment of this utility model, an annular groove 2144 is provided on the outer periphery of the annular protrusion 2142, and a sealing ring 2145 is provided in the annular groove 2144. The annular protrusion 2142 is sealed with the connecting port 213 through the sealing ring 2145.

[0052] In the above structure, an annular groove 2144 is provided on the outer periphery of the annular protrusion 2142, and a sealing ring 2145 is provided in the annular groove 2144. This fixes the sealing ring 2145 in the annular groove 2144, preventing the sealing ring 2145 from being pushed out of its original position and falling off the annular protrusion 2142 during long-term contact with the connecting port 213. The annular protrusion 2142 is sealed with the connecting port 213 through the sealing ring 2145, thereby ensuring the sealing between the annular protrusion 2142 and the connecting port 213. This prevents water from flowing through the gap between the annular protrusion 2142 and the connecting port 213 after the annular protrusion 2142 and the connecting port 213 come into contact. In one preferred embodiment, the ratio of the height of the portion of the sealing ring 2145 protruding from the bottom of the annular groove 2144 to the diameter of the sealing ring 2145 is between 20% and 40%. Within this ratio range, the main body of the sealing ring 2145 is located below the top of the annular groove 2144, effectively preventing the sealing ring 2145 from coming out of the annular groove 2144. At the same time, 20% to 40% of the sealing ring 2145 still protrudes from the top of the annular groove 2144, and this part can fully contact the connecting port 213 to ensure a good sealing effect.

[0053] After the filter element assembly 3 extends into the cavity, it is difficult to align the two second pipe segments 212 with the two pipe fittings 311 because the filter element assembly 3 obstructs the view of the second pipe segments 212. To solve this problem, in this embodiment of the invention, the outer shell 1 is tubular, and the cavity wall is provided with a guide groove 13 extending axially; the outer periphery of the filter element assembly 3 is provided with a guide protrusion 34 extending axially; the guide protrusion 34 guides and cooperates with the guide groove 13; the guide protrusion 34 is used to move along the guide groove 13 to a preset position so that the two pipe fittings 311 are correspondingly fitted with the two second pipe segments 212.

[0054] In the above structure, a guide groove 13 is provided on the cavity wall of the cavity, the guide groove 13 extends axially, and a guide protrusion 34 is provided on the outer periphery of the filter element assembly 3, the guide protrusion 34 extends axially, so that the guide protrusion 34 and the guide groove 13 guide each other. In this way, the guide groove 13 guides the guide protrusion 34 during the process of the filter element assembly 3 extending into the cavity, so that the relative angle between the filter element assembly 3 and the receiving assembly 2 is fixed each time the filter element assembly 3 extends into the cavity. This ensures that when the filter element assembly 3 extends into the preset position, the outer periphery of the two second pipe sections 212 and the two pipe fittings 311 are automatically aligned and correspondingly connected, reducing the difficulty of alignment.
