Such as the a2 interface 309 as the second inlet 162 and the A3 interface 310 as the first inlet 161 of fig. 5-6. Accordingly, it is easy to think of making the a2 interface as the first inlet and the A3 interface as the second inlet by appropriately changing the control method of the two-position three-way solenoid valve.

When the two-position, three-way solenoid valve 300 is used as the second switching valve 170, the port a1 serves as the third inlet 171. The a2 interface 309 and the A3 interface 310 serve as the second outlet 172 and the third outlet 173, respectively. Such as the a2 interface 309 as the third outlet and the A3 interface 310 as the second outlet 172 in fig. 1-2 and 5-6. Accordingly, it is conceivable to appropriately change the control method of the two-position three-way solenoid valve to make the a2 port as the second outlet and the A3 port as the third outlet.

As shown in fig. 18, when the electromagnetic coil 304 is energized, the electromagnetic force of the electromagnetic coil forces the sliding plug 314 to move upward against the elastic force of the first spring 313, the second plug 312 closes the second valve port 307, the first plug 311 opens the first valve port 306, and the a2 port 309 is communicated with the a1 port 308 through the first valve port 306, where the dotted line marked with an arrow in the figure indicates the direction of water flow.

The two-position three-way solenoid valve in the state shown in fig. 18 corresponds to the operating state of the first switching valve in fig. 5. If the water flow direction is opposite to that shown in fig. 18, the operation state of the second switching valve in fig. 1 and 5 corresponds thereto.

As shown in fig. 19, when the electromagnetic coil 304 is de-energized, the electromagnetic force of the electromagnetic coil disappears, the sliding plug 314 moves downward under the elastic force of the first spring 313, the first plug 311 blocks the first valve port 306, the second plug 312 opens the second valve port 307, and the A3 port 310 communicates with the a1 port 308 through the first valve port 306, and the dotted line of the marked arrow in the figure indicates the direction of water flow.

The two-position three-way solenoid valve in the state shown in fig. 19 corresponds to the operation state of the second switching valve in fig. 2 and 6. If the water flow direction is opposite to that shown in fig. 19, this corresponds to the operation state of the first switching valve in fig. 6.

In order to energize the electromagnetic coil, a trigger switch can be arranged to energize the electromagnetic coil when the hand-held ironing device is placed on the support, which can be realized by arranging the magnet on the support as shown in fig. 1 and 5 and arranging a magnetic control switch in the hand-held ironing device, i.e. when the hand-held ironing device is placed on the support, the magnetic control switch induces a magnetic field to directly close a power supply circuit of the electromagnetic coil, or a controller of the hand-held ironing device is instructed to energize the electromagnetic coil. Obviously, an equivalent technical means can replace the magnet and the magnetic control switch, such as a position switch is arranged on the hand-held ironing device, and the position switch directly closes a power supply circuit of the electromagnetic coil when the hand-held ironing device is placed on the support or enables a controller of the hand-held ironing device to electrify the electromagnetic coil.

The valve body is provided with a third spring 410, the valve body 402 is urged to move upward by the elastic force of the third spring, and the valve body is urged to move downward by the magnetic force of the interaction between the first magnetic attraction body 403 and the second magnetic attraction body 404 against the elastic force of the third spring.

The valve core 402 is rod-shaped and integrally formed with a third plug 413 corresponding to the third port and a fourth plug 414 corresponding to the fourth port, and the first magnetic element is mounted at the lower end of the valve core.

The B2 interface and the B3 interface are respectively used as a first inlet and a second inlet. As shown in fig. 1-2 and 3-4, the B2 interface is used as the second inlet, and the B3 interface is used as the first inlet. Accordingly, it is easy to think that the B3 interface is used as the second inlet and the B2 interface is used as the first inlet by appropriately changing the control method of the magnetic control switching valve.

When the magnetic control switching valve is used as a second switching valve, the B1 port is used as a third inlet. The B2 interface and the B3 interface are respectively used as a second outlet and a third outlet. 3-4, the B2 port serves as the third outlet and the B3 port serves as the second outlet. Accordingly, it is easy to think of making the B2 interface as the second outlet and the B3 interface as the third outlet by appropriately changing the control method of the magnetic control switching valve.

As shown in fig. 1 and 3, when the hand-held ironing device 100 is placed in the seat 200, the first magnetic element and the second magnetic element generate attractive magnetic force as shown in fig. 12, the valve core moves downward, the fourth plug 414 blocks 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 marked with an arrow indicates the direction of water flow.

If the direction of the water flow is opposite to that shown in fig. 12, this corresponds to the operation state of the second switching valve in fig. 4.

As shown in fig. 4, when the hand-held ironing device 100 leaves the support 200, the first magnetic element and the second magnetic element do not generate attractive magnetic force as shown in fig. 13, and the valve core moves upward, so that the fourth plug 414 opens the fourth valve port 409, the third plug 413 closes the third valve port 408, the B3 port 408 communicates with the B1 port 405 through the fourth valve port 409, and the dotted line with the marked arrow indicates the direction of water flow.

If the water flow direction is opposite to that shown in fig. 13, this corresponds to the operation state of the second switching valve in fig. 4.

In order to make the first magnetic attraction body and the second magnetic attraction body generate attractive magnetic force, when the hand-held ironing machine is placed on the support, the first magnetic attraction body and the second magnetic attraction body are close to each other.

Fig. 15 to 17 show another configuration of a magnetically controlled switching valve which differs from the configuration shown in fig. 10 to 14 in the following way: the B3 interface 407 is disposed at the upper end of the valve housing 401, the third port 408 and the fourth port 409 are oriented in the same direction, a third plug 413 corresponding to the third port and a fourth plug 414 corresponding to the fourth port are disposed on the valve core, and both the third plug and the fourth plug are located between the third port and the fourth port. 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 so that the first magnetic attraction body and the second magnetic attraction body 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 drive 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.
