[0041] The connection unit includes a C-shaped connection seat 201, an upper threaded connection head 202, a lower threaded connection head 203, a telescopic slot 204, a docking slot 205, a lifting cylinder 206, a sleeve cylinder 207, and a through hole 208;

[0042] The upper threaded connector 202 and the lower threaded connector 203 are symmetrically fixed at the upper and lower ends of the C-shaped connector 201, and the C-shaped connector 201 is spirally connected to the external pipe through the upper threaded connector 202 and the lower threaded connector 203;

[0043] The lower threaded connector 203 and the telescopic slot 204 are respectively disposed at the upper and lower ends of the inner wall of the C-shaped connector 201 and are respectively connected to the upper threaded connector 202 and the lower threaded connector 203;

[0044] The lifting cylinder 206 is vertically slidably connected to the interior of the lower threaded connector 203, the sleeve 207 is fixed to the bottom of the lifting cylinder 206, and the through hole 208 is opened at the top of the lifting cylinder 206;

[0045] The sleeve 207 is sleeved on the top outer side of the scale inhibitor outer tube 1, and the bottom of the scale inhibitor outer tube 1 is inserted into the inner side of the telescopic groove 204;

[0046] The plugging unit includes a plug 209;

A plurality of through holes 208 are provided in a ring shape with the sealing plug 209 as the center.

[0048] When the lifting cylinder 206 moves downward, the sealing plug 209 is separated from the inner cavity of the upper threaded connector 202, so that the upper threaded connector 202 and the inner cavity of the lifting cylinder 206 are connected;

[0049] When the lifting cylinder 206 moves upward, the sealing plug 209 is inserted into the inner cavity of the upper threaded connector 202, and the passage between the upper threaded connector 202 and the lifting cylinder 206 is cut off;

[0050] The disassembly and assembly unit includes a 7-shaped tooth arm 301, a transmission gear 302, a connecting shaft 303, a rotating arm 304, and a connecting crossbar 305;

[0051] The 7-shaped tooth arm 301 is fixed to one side of the outer wall of the sleeve 207 and is located between the inner side of the C-shaped connecting seat 201 and the outer cylinder 1 of the scale inhibitor;

[0052] The connecting shaft 303 is symmetrically fixed at both ends of the transmission gear 302. The transmission gear 302 is rotatably connected to the inside of the C-shaped connection seat 201 through the connecting shaft 303. The connecting shaft 303 penetrates to both ends of the outside of the C-shaped connection seat 201 and is fixedly connected to the rotating arms 304. The connecting cross bar 305 is fixed between the two rotating arms 304 and away from the connecting shaft 303.

[0053] The transmission gear 302 is meshed with the 7-shaped tooth arm 301. By pulling the connecting cross bar 305, the transmission gear 302 is driven to rotate to realize the up and down movement of the 7-shaped tooth arm 301, thereby realizing the sleeve connection and separation of the sleeve tube 207 and the scale inhibitor outer tube 1.

[0054] In this embodiment: it is necessary to supplementally explain that: when the C-type connection seat 201 is connected to the pipeline, the upper threaded connector 202 is connected to the water inlet pipeline, and a stainless steel adapter is provided at the end of the pipeline. The stainless steel adapter is threadedly connected with the upper threaded connector 202 and the lower threaded connector 203 to realize the connection between the C-type connection seat 201 and the pipeline;

[0055] During daily use, water in the water inlet pipe enters the outer cylinder 1 of the scale inhibitor through the upper threaded connector 202, the inner cavity of the telescopic slot 204, the through hole 208, and the inner cavity of the lifting cylinder 206, is filtered by the filter element inside the outer cylinder 1 of the scale inhibitor, and then is transported to the water use end through the lower threaded connector 202;

[0056] When it is necessary to replace the filter element inside the outer cylinder 1 of the scale inhibitor, the operation steps are as follows:

[0057] The connecting cross bar 305 is manually pulled to rotate upward, and the connecting cross bar 305 drives the transmission gear 302 to rotate through the two rotating arms 304 and the connecting shaft 303, and the transmission gear 302 pushes the 7-shaped tooth arm 301 to move upward, and the 7-shaped tooth arm 301 pushes the sleeve tube 207, the lifting tube 206 and the sealing plug 209 to move upward synchronously, and the sealing plug 209 moves upward and is inserted into the inner cavity of the upper threaded connector 202 to achieve the blocking of the upper threaded connector 202, and at the same time, the sleeve tube 207 moves upward and separates from the top of the scale inhibitor outer tube 1 (it should be supplemented that: at this time, the scale inhibitor outer tube 1 can be supported by another hand to keep the scale inhibitor outer tube 1 immovable), and then the scale inhibitor outer tube 1 is pulled upward to separate it from the docking groove 205, so that the scale inhibitor outer tube 1 is disassembled;

[0058] After that, the filter element inside the outer cylinder 1 of the scale inhibitor can be replaced, and then the outer cylinder 1 of the scale inhibitor is inserted into the docking groove 205, and then the connecting cross bar 205 is pulled downward, so that the 7-shaped tooth arm 301 moves downward and drives the sleeve tube 207 to be sleeved on the top of the outer cylinder 1 of the scale inhibitor, and at the same time, the sealing plug 209 releases the sealing of the upper threaded connector 202, and the replacement of the filter element is completed at this time;

[0059] The cooperation of the above multiple parts can realize the convenient replacement of the filter element inside the outer tube 1 of the scale inhibitor. Different from the traditional method of disassembling the scale inhibitor by a wrench, the operation is simpler and more convenient, and non-professionals can also operate it conveniently.

[0060] Please refer to Figures 1 to 4 , the limiting unit includes an elastic block 306, a limiting guide rod 307, and a limiting guide groove 308;

[0061] The elastic clamping blocks 306 are symmetrically fixed to the upper and lower ends of the outer side of the C-shaped connecting seat 201, and the connecting crossbars 305 at the highest and lowest positions are clamped with the side surfaces of the elastic clamping blocks 306 to limit the position of the connecting crossbars 305;

[0062] The limiting guide groove 308 is opened at the top of the C-shaped connecting seat 201 and extends to the inner side of the C-shaped connecting seat 201. The limiting guide rod 307 is fixed to the top of the 7-shaped tooth arm 301. The limiting guide rod 307 is slidably connected to the limiting guide groove 308 for limiting the up and down movement of the 7-shaped tooth arm 301.

[0063] In this embodiment, it should be supplemented that the elastic block 306 itself has a certain elasticity, and the end of the elastic block 306 is formed with an arc operation that matches the trajectory of the outer wall of the connecting cross bar 305. When the connecting cross bar 305 rotates to contact the elastic block 306, the elastic block 306 will be squeezed to deform it. When the connecting cross bar 305 completely passes through the elastic block 206 to the uppermost or lowermost end, the elastic block 306 will reset under the action of its own elastic force and fit with the outer wall of the connecting cross bar 305 to limit the connecting cross bar 305.

[0064] In addition, through the limiting sliding structure of the limiting guide rod 307 and the limiting guide groove 308, the 7-shaped tooth arm 301 can only move up and down but cannot rotate, thereby ensuring the stable meshing state of the 7-shaped tooth arm 301 and the transmission gear 302.

[0065] Please refer to Figure 4 The bottom of the descending tube 206 and the bottom of the scale inhibitor outer tube 1 are fixedly connected with a hollow net 4, and the inner cavities of the telescopic groove 204, the docking groove 205 and the sleeve tube 207 are all installed with sealing rings.

[0066] In this embodiment: the filter element inside the outer cylinder 1 of the scale inhibitor can be supported and limited by the hollow mesh 4 to ensure stable installation of the filter element;

[0067] The sealing ring can ensure good sealing between the telescopic groove 204 and the lifting cylinder 206, as well as the sleeve connection 207, the docking groove 205 and the outer cylinder 1 of the scale inhibitor.

[0068] Please refer to Figures 1 to 4 After the sleeve 207 moves upward, the distance between it and the top of the scale inhibitor outer tube 1 is greater than the depth of the docking groove 205.

[0069] In this embodiment: through this structure, after the scale inhibitor outer tube 1 is separated from the docking groove 205, the top of the scale inhibitor outer tube 1 does not contact the sleeve tube 207, thus ensuring the smooth disassembly and assembly operation of the scale inhibitor outer tube 1.

[0070] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
