Specifically, as shown in fig. 9 and 10, in the present embodiment, the scale inhibition module 1 also employs the metal rod 2. The metal rod 2 includes a metal body 21 and a core rod 22, the metal body 21 is a tubular structure made of magnesium metal, and the metal body 21 is used for losing electrons. A through hole is formed in the metal body 21 along the axis direction, the through hole is a blind hole with one closed end, the core rod 22 is arranged in the through hole in a penetrating manner, and the first end of the core rod 22 protrudes out of the through hole. And, the first end of the core rod 22 can pass through the scale inhibition module 1 to be connected with the blow-off valve 3.

As shown in fig. 9 and 10, in the present embodiment, the scale inhibition module 1 includes a scale inhibition bottle, an inner tube 116 and a scale inhibition body 14, the scale inhibition bottle includes a bottle body 11 and a bottle cap 12, the bottle body 11 is in a barrel-shaped structure, and optionally, the bottle body 11 is in a cylindrical shape. Specifically, the bottle body 11 specifically includes an injection-molded part 111 in a barrel shape and a filter mesh sheet 112. The injection molding piece 111 is a main supporting part of the filter flask, is made of plastic and is integrally formed by adopting an injection molding process, so that the cost is low and the manufacturing is convenient. The injection molding 111 specifically comprises a top annular plate and a bottom cover plate which are arranged up and down, a plurality of reinforcing ribs are arranged between the top annular plate and the bottom cover plate, and mounting holes for mounting the filter mesh 112 are formed between adjacent reinforcing ribs. The filter mesh 112 is made of stainless steel material, and is covered at the mounting hole and is fixedly connected inside the injection molding piece 111. The filter mesh 112 is used for realizing the communication between the inside and the outside of the scale inhibition bottle and preventing foreign matters from entering the inside of the scale inhibition bottle. The mesh holes on the filter mesh 112 are the overflow holes 13 for water to flow into and out of the scale inhibition bottle. The bottle cap 12 is covered on the bottle body 11, and the connection mode is not limited, and can be welded, screwed or connected by a connecting piece.

The inner tube 116 is located inside the bottle body 11, a first preformed hole communicated with the tube hole of the inner tube 116 is formed in a bottom cover plate of the bottle body 11, a second preformed hole communicated with the tube hole of the inner tube 116 is formed in the bottle cap 12, and the first preformed hole, the inner tube 116 and the second preformed hole are sequentially communicated to form an avoiding channel allowing the core rod 22 to pass through. The scale inhibitor 14 is filled between the outer wall of the inner tube 116 and the inner wall of the body 11. At least part on the inner wall of the second preformed hole is provided with internal threads, so that a third threaded hole 122 is formed in the second preformed hole, correspondingly, a fourth stud 211 is arranged at one end, close to the scale inhibition module 1, of the metal body 21, and the fourth stud 211 is in threaded connection with the third threaded hole 122, so that threaded connection between the metal rod 2 and the scale inhibition module 1 is achieved.

The first end of the mandrel 22 can pass through the second preformed hole, the inner tube 116 and the first preformed hole into the first threaded hole 32 and connect with the waste valve 3. Optionally, a third stud 222 is provided on the first end of the mandrel 22, and the threaded connection of the third stud 222 to the first threaded hole 32 enables the removable connection of the mandrel 22 and the waste valve 3. At this time, since the scale inhibition bottle is sleeved on the core rod 22, the scale inhibition module 1 can be fixed after the core rod 22 is screwed with the blowoff valve 3.

Further, in order to improve the connection strength between the scale inhibition bottle and the drain valve 3, connecting holes are formed in the bottom cover plate of the scale inhibition bottle and the drain valve 3, and the connecting holes are arranged by penetrating through the connecting holes, so that the connection strength between the scale inhibition bottle and the drain valve 3 is improved. Specifically, as shown in fig. 10, a fourth threaded hole 117 is provided on the bottom cover plate opposite to the blowoff valve 3 on the dirt-removing bottle, a fifth threaded hole 37 is provided on one end of the blowoff valve 3 opposite to the dirt-removing bottle, and a screw passes through the fifth threaded hole 37 and the fourth threaded hole 117 to screw-connect the dirt-removing bottle with the blowoff valve 3.

Of course, the corrosion prevention module, the scale inhibition module 1 and the blow-off valve 3 are also applicable to other detachable connections besides threaded connection, and are not listed here.

It is obvious that the above embodiments of the present invention are only examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments.
