It is provided with sealing ring 54.For filtering water, it is additionally provided with strainer 141 in valve inleting water mouth 14, strainer 141 can select steel wire
Gauze.
As shown in Fig. 4 a and Fig. 5, in one embodiment, the dynamic iron core 22 has magnetism, and in the side of dynamic iron core
It is additionally provided with permanent magnet 24.Permanent magnet 24 is used to apply the magnetic force along 22 moving direction of dynamic iron core to dynamic iron core 22, and dynamic iron core exists
Along the axis of dynamic iron core 22 under the magnetic force of elastic force, the magnetic force that permanent magnet 24 provides and coil generation that first spring 23 provides
Line direction is gone, so that the movement in the valve chamber of diaphragm unit 3 be driven to make the valve body on and off.
In 22 attracting state of dynamic iron core (at this time valve body conducting also call off valve), i.e., dynamic iron core 22 close to static iron core 221 and
When far from diaphragm unit 3, the magnetic force that permanent magnet 24 provides is directed toward static iron core 221 and is greater than the spring of the first spring 23, thus
Stablize dynamic iron core 22 in attracting state.Inputting a pulse signal to coil 213 at this time makes coil 213 generate magnetic field, coil 213
The magnetic field of generation applies the magnetic force for being directed toward diaphragm unit 3 to dynamic iron core 22, which is superimposed greatly with the elastic force of the first spring 23
In the magnetic force of permanent magnet 24, to drive dynamic iron core 22 mobile to 3 direction of diaphragm unit, so that push-rod assembly be made to stopper relief hole
431, so that diaphragm 32 is moved down valve body.During dynamic iron core 22 is mobile to diaphragm unit 3, dynamic iron core 22 and permanent magnet 24
Positional relationship change, so that so that permanent magnet 24 is changed the magnetic force direction of dynamic iron core 22 (is changed to point to diaphragm group
3 direction of part), dynamic iron core 22 keeps discrete state (valve at this time under the elastic force of the first spring 23 and the magneticaction of permanent magnet 24
Body closing, which is also named, closes valve), i.e., dynamic iron core 22 separates with static iron core 221 and compresses diaphragm unit 3.In dynamic iron core 22 by discrete state
When switching to attracting state, coil 213 generates opposite magnetic force, which is greater than the magnetic force of the first spring 23 and permanent magnet 24,
To drive dynamic iron core 22 mobile to 221 direction of static iron core, it is similar that the process and above-mentioned attracting state switch to discrete state, this
In just repeat no more.
Preferably, permanent magnet 24 is located at the actuation equalization point of dynamic iron core 22, wherein be attracted equalization point be dynamic iron core 22 by
22 Impact direction switching point of dynamic balance point and dynamic iron core, when dynamic iron core 22, which is in, is attracted equalization point, the stress of dynamic iron core 22
It is zero.The middle part that dynamic iron core 22 is moved to movement routine can be located at by being attracted equalization point, when dynamic iron core 22 is moved to actuation equalization point
When permanent magnet 24 be zero to the magnetic force of dynamic iron core 22, and be more than the actuation equalization point and close to static iron core when dynamic iron 22 is mobile
When 221, permanent magnet 24 is to the direction static iron core 221 of dynamic iron core 22, and permanent magnet 24 is greater than first to the magnetic force of dynamic iron core 22
The magnetic force of spring, so that dynamic iron core be made to be maintained at close to 211 state of static iron core (compressing the first spring state)；When dynamic iron core 22
Mobile when being more than that this is located proximate to diaphragm unit 3, permanent magnet 24 is to the direction diaphragm unit 3 of dynamic iron core 22, thus by dynamic iron core
It is maintained at and compresses 3 state of diaphragm unit.
As shown in fig. 6, in one embodiment, the surface of liquid when in order to further decrease dynamic iron core 22 far from static iron core
Power is provided with opening 223 in the side of 22 dynamic iron core 22 of dynamic iron core, and opening 223 is by channel 224 and is located at 22 end face of dynamic iron core
Groove 221 be connected, wherein channel 224 can be located inside and one end and open communication, the other end and the groove of dynamic iron core 22
221 connections.When mobile to diaphragm direction under magneticaction of the dynamic iron core in coil 213, due to being located at 22 end face of dynamic iron core
Groove 221 is connected with the opening of 22 side of dynamic iron core, therefore the air-flow of 22 side of dynamic iron core can be by opening 223 and channel 224
Into groove 221, to reduce the surface tension of the liquid of 22 end face of dynamic iron core attachment, to make to drive the movement of dynamic iron core 22
Coil magnetic force can be smaller, therefore keeps the function of electromagnet lower.
In one embodiment, the stroke of the dynamic iron core is 0.3~0.5mm, is moved in relatively existing bistable electromagnetic valve
The stroke of iron core is smaller.And the stroke of dynamic iron core reduces, and the volume of solenoid valve can be made smaller, and can reduce coil 213 to dynamic
The driving force of iron core 22 keeps the energy consumption of coil 213 lower.
Due to being provided with groove 221 in the end face of dynamic iron core 22, the liquid tension pair of 22 end face of dynamic iron core attachment is reduced
The mobile resistance of dynamic iron core, and the stroke of dynamic iron core reduces, to make coil 213 that iron core can be driven using lesser magnetic force
22 is mobile, therefore, the pulse voltage of the size of the pulse voltage of coil 213 and period (i.e. duration) relatively existing solenoid valve
Smaller, to keep it more energy saving, energy consumption is lower.Specifically, in one embodiment, coil 213 described in bistable electromagnetic valve
Resistance value be the Ω of 13 Ω~17, the pulse voltage of coil 213 is 2.7V~4.1V, the pulse period (duration) be 7ms~
12ms, the magnetic flux density in the magnetic field that electromagnet coil 213 generates when being powered are 2700GTS~3300GTS, and permanent magnet 24 is resistance to
The neodymium iron boron strong magnets of 120 DEG C of high temperature (heatproof of conventional magnet is 80 DEG C).Since this solenoid valve can be used for normal-temperature water and height
Warm water, the heatproof of conventional magnet only have 80 DEG C or so, at high operating temperatures easy loss of excitation, and resistance to 120 DEG C of height are used in the present embodiment
The neodymium iron boron strong magnets of temperature, it is ensured that permanent magnet 24 is still magnetic at high operating temperatures.The pulse of existing bistable electromagnetic valve
Voltage between 4.4V~6.6V, the pulse period in 25ms or more, in the present embodiment, the pulse voltage and pulse of coil 213
Period is respectively less than pulse voltage and the pulse period of existing bistable electromagnetic valve, therefore its energy consumption is also lower.
As shown in Figure 8 and Figure 9, a kind of induction discharging device is provided in another embodiment, which can root
According to the actuated signal control water outlet detected, it is specifically as follows the discharging devices such as inductive faucet, Induction flushing device.Induction water outlet
