In the process of softening the resin in the resin tank 6, two steps of water injection and salt absorption are required.

Water injection step: as shown in Figures 1 and 4, water is first injected into the salt tank 7, at which time the ionization generator 1 is not working, the electric air valve 1-3 is in a closed state, the pneumatic tube b10 is not connected, and the water flow is first introduced into the control valve 5 , through the salt suction port 5-1 through the three-way quick-connect pipe 3 into the installation valve 8, the density of the float ball 8-1 is less than water, it will float upward, the water passes through the cavity 8-5, the valve body 8-4 side The wall enters the salt tank 7 and melts the salt to form brine.

Salt absorption step: As shown in Figures 1 and 5, the control valve 5 generates suction, and the brine in the salt tank 7 is sequentially sucked into the salt absorption port 5-1 through the mounting valve 8 and the three-way quick connection pipe 3, and then passed through the resin tank center pipe. 6-1 enters the resin tank 6, and the salt resin reacts chemically, so that the resin has the soft water function again. After the salt water is sucked, the float ball 8-1 of the safety valve 8 falls, and the sealing ring 8-2 is sealed, and the water pipe b) closure. At this time, the ionization generator 1 does not work, and the pneumatic tube b10 still does not pass.

After the salt absorption step is completed, the elimination operation is performed: as shown in FIGS. 1 and 6, the control circuit 4 on the control valve 5 sends the electric gas valve 1-3 of the ionization generator 1 and the ionization device 1-4 to open the signal, and the electric gas Valves 1-3 open the air outlet 1-2. At this time, the control valve 5 still maintains suction, and air passes through the drying tube 2 to obtain dry air, and the dried air enters the ionization generator 1, and the ionization device 1-4 ionizes oxygen in the dry air to generate ozone. The generated ozone enters the resin tank 6 through the three-way quick-connect pipe 3, the salt suction port 5-1, and the center pipe 6-1, and sterilizes the resin in the resin tank 6. After the set time has elapsed, the control circuit 4 sends a signal to the electric air valve 1-3 and the ionizing device 1-4 to turn off, the ionizing device 1-4 stops working, and the electric air valve 1-3 closes the air outlet 1-2.

The above description is only a preferred embodiment of the present invention, and it should be noted that those skilled in the art can also make several improvements and retouchings without departing from the principles of the present invention. It should be considered as the scope of protection of the present invention.
