The rest of the structure is the same as the structure shown in fig. 10-14, and is not repeated.

When the first magnetic element and the second magnetic element generate attractive magnetic force as shown in fig. 16, and the valve core moves downward, the fourth plug 414 opens the fourth valve port 409, the third plug 413 closes the third valve port 408, the B3 port 407 communicates with the B1 port 405 through the fourth valve port 409, and the dotted line of the labeled arrow in the figure indicates the direction of water flow.

When the first and second magnetic elements do not generate attractive magnetic force as shown in fig. 17, and the valve core moves upward, the fourth plug 414 closes the fourth valve port 409, the third plug 413 opens the third valve port 408, the B2 port 406 communicates with the B1 port 405 through the third valve port 408, and the dotted line of the labeled arrow indicates the direction of water flow.

Thus, the magnetically controlled switching valves shown in fig. 15-17 may be substituted for the magnetically controlled switching valves of the configurations shown in fig. 10-14.

Considering that the inlet water pressure of the water pump is negative pressure, the outlet water pressure of the water pump is positive pressure. Therefore, when the hand-held ironing machine is placed on the support to enable the first magnetic attraction body and the second magnetic attraction body to generate attraction magnetic force, the magnetic control conversion valve with the structure shown in fig. 10-14 is preferably used as the first conversion valve, and the negative pressure generated by the water pump can assist the electromagnetic force to enable the valve core to overcome the elastic force of the third spring. When the hand-held ironing device is separated from the support so that the first magnetic attraction body and the second magnetic attraction body do not generate attraction magnetic force, the magnetic control switching valve with the structure shown in fig. 15-17 is preferably used as the second switching valve, and positive pressure generated by the water pump can assist the elastic force of the third spring to enable the magnetic control switching valve to be in the state shown in fig. 17.
