Second embodiment

The application also provides a scale inhibition and scale removal module 102, which comprises a shell 6, wherein the shell 6 defines a first water channel 61 and a second water channel 62 which are arranged independently, the shell 6 is provided with a cavity 621 for containing scale inhibition and scale removal agents, and the cavity 621 forms a part of a path of the second water channel 62; the housing 6 has a water outlet 63; wherein the first waterway 61 is configured to limit the second waterway 62 to communicate with the water outlet 63 under the action of the water flow pressure in the first waterway 61; the second waterway 62 is configured to allow an external water flow into the receptacle 621 when the water pressure in the first waterway 61 is released, so that the second waterway 62 communicates with the water outlet 63.

The scale inhibition and removal module 102 has two water paths which are arranged independently; when the first water path 61 is opened, that is, when external inlet water flows through the first water path 61 and is discharged to an external equipment pipeline from the water outlet 63 of the shell 6, the second water path 62 is in a closed state, no flowing water is introduced into the second water path 62 at this time, and the scale inhibitor and scale remover in the cavity 621 is not soaked; when the first water path 61 stops flowing water, that is, the first water path 61 is closed, the second water path 62 is in a conducting state, that is, external water flows into the cavity 621 through the second water path 62 to soak the scale inhibiting and removing agent, and the soaked scale inhibiting and removing solution is released from the water outlet 63 of the shell 6 and permeates into an external equipment pipeline.

The scale inhibition and scale removal module 102 is characterized in that after the second water path 62 is conducted, namely the whole process that the second water path 62 discharges scale removal and scale removal solution, the scale inhibition and scale removal agent in the cavity 621 is soaked, dissolved and changed into the state of the scale inhibition and scale removal solution, so that the scale inhibition and scale removal agent can be effectively utilized, the discharge time of the scale inhibition and scale removal solution is longer, effective scale inhibition and scale removal operation is performed on external equipment pipelines to be fully descaled, and the scale inhibition and scale removal effect is good.

In addition, because the first water channel 61 and the second water channel 62 are independent of each other, in the whole process of the operation of the first water channel 61, namely in the state of normal water communication, the scale inhibition and removal solution cannot permeate, and normal water use can be ensured; when the external equipment pipeline to be descaled is subjected to scale inhibition and descaling treatment, the first water channel 61 is in a closed state, so that normal water cannot be introduced into the external equipment pipeline to be descaled to influence the concentration of the scale inhibition and descaling solution, and the scale inhibition and descaling effects of the scale inhibition and descaling solution are effectively guaranteed.

In the present application, the scale and scale inhibiting and removing module 102 further includes a power mechanism 7 located in the housing 6, wherein the power mechanism 7 is configured to seal the cavity 621 under the water flow pressure in the first water path 61.

After the water supply in the first water path 61 is stopped, the pressure of water flow does not exist in the first water path 61 any more, the closed state of the cavity 621 is released, the second water path 62 is in a conducting state, external water flow enters the second water path 62, and the scale inhibition and scale removal agent is dissolved in water and then is diffused into an external equipment pipeline through the water outlet 63. The scale inhibition and scale removal module 102 is always in a closed state when water is normally used, and the scale inhibition and scale removal solution cannot leak to affect the normal water use; after the first water channel 61 stops supplying water, the external water flow enters the cavity 621 to continuously soak and dissolve the scale inhibition and removal agent, so that the scale inhibition and removal effects are better.

In the scale inhibition and scale removal module, the scale inhibition and scale removal agent in the cavity 321 is only soaked in the water temporarily stored in the cavity, so that the water soaking amount is small, and the service life of the scale inhibition and scale removal agent is prolonged.

When the water inlet 33 is closed, the pressure of the water flow in the first water path 32 is no longer present, the power mechanism 4 moves in the housing 3 in the opposite axial direction (for example, moves in the axial direction of the housing 3 toward the first end 391 of the housing 3), and when the power mechanism 4 compresses the cavity 321 to open the second water path 12, the scale inhibiting and removing solution temporarily stored in the cavity 321 is released to the outside of the housing 3 through the second water path 32 and permeates into the external equipment pipeline to be descaled.
