The present invention will be described in detail with reference to the following embodiments and accompanying drawings.

Example 1

As shown in fig. 1-3, 4 and 5, respectively, are schematic diagrams of a magnetic valve assembly, a water pump control circuit and a steam ironing device.

The magnetic valve assembly shown in fig. 1-3 is an example of a three-way valve as the magnetic valve 101. The magnetic valve assembly comprises a magnetic valve 101 and a position switch 102. The magnetic control valve 101 comprises a valve housing 103, a valve core 104, a first magnetic attraction body 105 and a second magnetic attraction body 106, wherein a first interface 111, a second interface 112 and a third interface 113 which are used for being connected in a water delivery path are arranged on the valve housing 103 from top to bottom, a first valve port 114 and a second valve port 115 are arranged in the valve housing 103, and the valve core 104 is movably arranged in the valve housing 103 and opens or closes the first valve port 107 and the second valve port 114 through the movement transposition of the valve core 104. The first magnetic attraction body 105 is fixedly arranged at the lower end of the valve core 104, the second magnetic attraction body 106 is arranged outside the valve casing and is separated from the valve casing, and the valve core is moved and transposed by the change of the mutual positions of the first magnetic attraction body and the second magnetic attraction body.

In fig. 1-3, the valve housing 103 is provided with an expansion link 109, the expansion link is located at one side of the valve core 104, the expansion link 109 is provided with a third magnetic attraction body 110, and the synchronous movement and the transposition of the expansion link 109 and the valve core 104 are realized by the mutual position change of the third magnetic attraction body 110 and the second magnetic attraction body 106. When the telescopic rod is implemented specifically, a fourth magnetic attraction body can be additionally arranged, and the synchronous movement and the transposition of the telescopic rod and the valve core are realized by the change of the mutual positions of the third magnetic attraction body and the fourth magnetic attraction body, which is equivalent to dividing the second magnetic attraction body into two parts.

As shown in fig. 2, when the first port 107 is closed and the second port 114 is opened by the valve element 104 under the action of the first coil spring 115, the second port 112 and the third port 113 are communicated, and the first port 111 is disconnected from the second port 112 and the third port 113. This situation is equivalent to the case that the magnetic control valve 101 is arranged in the hand-held ironing device 301, the second magnetic attraction body 106 is fixed in the base 302, and the hand-held ironing device 301 is removed 302 from the base.

As shown in fig. 2, the telescopic rod 109 is acted by the second coil spring 116 to actuate the upper position switch 102, so that the position switch is in the first working state, and a first signal is generated.

As shown in fig. 3, the valve element 104 is attracted by the first magnetic attraction body 105 and the second magnetic attraction body 106 to compress the first coil spring 115, and the valve element 104 moves downward relative to the position shown in fig. 2 to open the second valve port 114 and close the first valve port 107, at this time, the first port 111 is communicated with the second port 112, and the third port 113 is disconnected from the first port 111 and the second port 112. This situation is equivalent to the magnetic control valve 101 being disposed in the hand-held ironing device 301, the second magnetic attraction body 106 being fixed in the base 302, and the hand-held ironing device 301 being placed on the base 302.

As shown in fig. 3, the telescopic rod 109 is attracted by the third magnetic attraction 110 and the second magnetic attraction 106 to compress the second coil spring 116, and the telescopic rod 109 moves downward relative to the position shown in fig. 2, and is away from the position switch 102 above, so that the position switch is in the second working state to generate a second signal. The second signal is distinguished from the first signal to be provided to the controller, and the controller makes corresponding instructions according to the different second signal and the first signal.

In fig. 2 and 3, the telescopic rod and the valve core are synchronized in their movements. In the two operating states of fig. 2 and 3, the position switch generates a change signal, i.e. a change between the first signal and the second signal. Therefore, the position switch is preferably a microswitch.

In fig. 1-3, the first and second magnetic attraction bodies, and the third and second magnetic attraction bodies realize corresponding actions through the attraction force. In view of the nature of the magnetic attraction bodies, in specific implementation, the first magnetic attraction body and the second magnetic attraction body, and the third magnetic attraction body and the second magnetic attraction body can generate repulsive force to realize corresponding actions.

In this embodiment, the position switch 102 is assembled with the valve housing 103. In particular embodiments, the position switch may be deployed separately from the valve housing, such as by being assembled separately from the valve housing in a hand-held ironing machine.

In particular, the position switch 102 and the spool 104 are configured such that the spool opens or closes the valve port earlier than the position switch generates the change signal. Taking the application of the magnetic valve assembly with the structure shown in the figure to a steam generating device as an example, when the state shown in fig. 2 and the state shown in fig. 3 change, the valve core is moved to the position first, and then the position switch generates a corresponding change signal.

Fig. 4 is a schematic diagram of a water pump control circuit. The water pump control circuit can be applied to the steam generating device shown in fig. 5. The water pump control circuit comprises a water pump 201, a controller 202 and a magnetic control valve assembly 100, wherein the controller is used for controlling the water pump to work. The magnetic control valve 101 is located in a water delivery path of the water pump, and when the valve core opens or closes the valve port, the controller 202 controls the working state of the water pump to change according to a change signal generated by the position switch 102. Particularly, the controller controls the flow of the water pump according to a change signal generated by the position switch, so that the water pump works at a large flow rate when water is supplemented, and works at a small flow rate when steam is generated. The control circuit further includes an operation indicator lamp 204, a load 203, a protection switch 205, a power switch 206, and the like. When the water pump control circuit is applied to the steam generating device shown in fig. 5, the load is a heating boiler (steam generator), and the protection switch is a temperature controller.

The steam generating device 300 shown in fig. 5, like the moisturizing ironing device described in the background art, includes a handheld ironing device 301 and a base 302, the control circuit shown in fig. 4 is applied to the steam generating device shown in fig. 5, and the magnetron valve assemblies shown in fig. 1-3 are used as the first switching valve and the second switching valve in the moisturizing ironing device, so that the function of the moisturizing ironing device can be realized, and the change of the working state of the water pump can be accurately controlled to be in pace with the working requirement of the household appliance.

The first magnetic attraction body 105a is fixed at the lower end of the valve core 104a, the second magnetic attraction body 106a is disposed outside the valve housing 103a and separated from the valve housing, and the valve core is moved and repositioned by changing the mutual positions of the first magnetic attraction body and the second magnetic attraction body.

In fig. 6-7, the valve housing 103a is provided with a telescopic rod 109a, the telescopic rod is located at one side of the valve core, the telescopic rod is provided with a third magnetic attraction body 110a, and the synchronous movement and the transposition of the telescopic rod and the valve core are realized by the change of the mutual position of the third magnetic attraction body and the second magnetic attraction body. When the telescopic rod is implemented specifically, a fourth magnetic attraction body can be additionally arranged, and the synchronous movement and the transposition of the telescopic rod and the valve core are realized by means of the change of the mutual positions of the third magnetic attraction body and the fourth magnetic attraction body. This is equivalent to dividing the second magnetic attraction body into two parts.

As shown in fig. 6, when the third coil spring 115a acts on the valve body 104a to close the third port 107a, the fourth port 111a is disconnected from the fifth port 112a, and the magnetic control valve is in the off state.

As shown in fig. 6, the telescopic rod 109a is acted by the fourth coil spring 116a to actuate the upper position switch 102a, so that the position switch is in the first working state, and generates a first signal.

As shown in fig. 7, the valve element 104a is attracted by the first magnetic attraction 105a and the second magnetic attraction 106a, and compresses the third coil spring 115a, so that the valve element 104a moves downward relative to the position shown in fig. 6, and opens the third valve port 107a, and at this time, the fourth port 111a and the fifth port 112a are disconnected, and the magnetic valve is in a conducting state.

As shown in fig. 7, the telescopic rod 109a is attracted by the third magnetic attraction 110a and the second magnetic attraction 106a, and compresses the fourth coil spring 116a, so that the telescopic rod 109a moves downward relative to the position shown in fig. 6, and is away from the position switch 102a above, so that the position switch is in the second working state, and generates a second signal. The second signal is distinguished from the first signal to be provided to the controller, and the controller makes corresponding instructions according to the different second signal and the first signal.

In fig. 6 and 7, the telescopic rod and the valve core are synchronized in their movements. In the two operating states of fig. 6 and 7, the position switch generates a change signal, i.e. a change between the first signal and the second signal.

Example 3

As shown in fig. 8-9, is another structural schematic diagram of the magnetic control valve assembly. The magnetic valve assembly is an example of a two-way stop valve as a magnetic valve.

The magnetic valve assembly 100b includes a magnetic valve 101b and a position switch 102 b. The magnetic control valve 101b includes a valve housing 103b provided with a fourth port 111b and a fifth port 112b, a valve body 104b provided with a third port 107b, a first magnetic element 105b, and a second magnetic element 106b, and is movably disposed in the valve housing and configured to open or close the third port by a movement thereof. The first magnetic attraction body is fixedly arranged at the lower end of the valve core, the second magnetic attraction body is arranged outside the valve shell and is separated from the valve shell, and the valve core is moved and transposed by means of the change of the mutual positions of the first magnetic attraction body and the second magnetic attraction body.

The valve rod touches the position switch above the valve rod, so that the position switch is in a first working state and generates a first signal.

As shown in fig. 9, the valve element 104b is attracted by the first magnetic attraction body 105b and the second magnetic attraction body 106b, and compresses the third coil spring 115b, so that the valve element 104b moves downward relative to the position shown in fig. 6, and opens the third port 107b, and at this time, the fourth port 111b and the fifth port 112b are disconnected, and the magnetic valve is in a conducting state. The valve stem 108 is moved downward relative to the position shown in fig. 6, away from the upper position switch 102b, to place the position switch in a second operating state, generating a second signal.

In the two operating states of fig. 8 and 9, the position switch generates a change signal, i.e. a change between the first signal and the second signal.

The magnetic valve assembly described in the above embodiments 2 and 3 can be used in a coffee machine to close or open the water supply path at a proper time.

Taking a steam ironing device as an example, the ironing device relies on water delivery and water vaporization to steam to realize the ironing function. Coffee machines rely on the delivery of water, heating the water to hot water, or vaporization to brew coffee.

As shown in the figures, the volume of the magnetron valve assemblies of embodiments 1 and 2 is large because the magnetron valve assemblies are provided with the telescopic rods. But the work of telescopic link need not sealed, and the structure is easily set up, and the action of telescopic link only bears second coil spring, magnetic force effect when moving, and these two kinds of power are stable moreover, therefore the action of telescopic link is easily controlled. The magnetic control valve component of the embodiment 3 is not provided with a telescopic rod, so that the size of the magnetic control valve is smaller. However, since the seal ring 116b needs to be disposed in the valve stem, the risk of water leakage increases, and the elastic force and the magnetic force of the third coil spring need to be increased to ensure the valve body operation.
