As shown in Figure 1, 2, electromagnetic mechanism includes: the coil 4 being wrapped on valve body 1, the iron core group being fixed on sealing-plug 2
Part, coil 4 are wrapped on the lateral wall at 1 upper inlet end of valve body, and core assembly includes the evenly arranged iron of multiple circular sealing-plugs 2
Core 5, attracts core assembly to move to the centre of coil 4 when coil 4 is powered, the winding position of coil 4 determines the movement of sealing-plug 2
Position can be set according to actual needs.
When electromagnetic mechanism powers off, sealing-plug 2 is pushed into get lodged in import 11 by spring 3 along its direction of extension, at this time electromagnetism
Valve is in off state, and pushes sealing-plug 2 to be detached from import along the shrinkage direction of spring 3 when electromagnetic mechanism is powered, at this time solenoid valve
It is in an open state, liquid enters in valve body 1 from import 11 flows through overcurrent region again from the outflow of outlet 12, and sealing-plug 2 is being moved through
The flow direction of the shrinkage direction of spring 3 liquid in valve body 1 in journey is not in the phenomenon that shaking by liquid knockout, close
The motion process of blocking 2 is very stable.
As shown in Figures 1 to 3, for the ease of the installation of spring 3, the center for exporting 12 is equipped with mounting base 13, the compression setting of spring 3
Between mounting base 13 and sealing-plug 2, mounting base 13 is connect by multiple ribs 14 for being fitted around the setting of seat 13 with outlet 12,
Guarantee not influencing the smooth outflow of liquid from outlet 12 while 13 connection structure of mounting base is secured.Preferably, since spring 3 is long
Time is in detergent the physical characteristic that can seriously affect spring 3, causes the movement delay of spring 3, therefore in order to protect spring
3, the service life for extending solenoid valve, is additionally provided with protective case 6 between mounting base 13 and sealing-plug 2, spring 3 is placed in protective case 6,
Spring 3 is separated with detergent by protective case 6.In a preferred embodiment, protective case 6 is made of hard material, protection
One end of set 6 is fixing end, the other end is to stop end, and fixing end is connected in mounting base 13, stops to stay between end and sealing-plug 2
There is spacing, sealing-plug 2, which can move to be against to the direction for being detached from import 11, to be stopped on end, and liquid is flowed from import 11 to outlet 12
When sealing-plug 2 cover stop end, effectively avoid detergent from stop end flow into protective case 6 in.It certainly, in actual use can also be with
Protective case is made using soft material, one end of protective case 6 is connected in mounting base 13, the other end is connected on sealing-plug 2, this
When protective case 6 there is no limit 2 limit of sports record distance of sealing-plug effect, the less reliable of solenoid valve 100.
Further, as shown in Figures 1 to 3, the center of mounting base 13 is equipped with pilot hole 15, and sealing-plug 2 is equipped with across bullet
The guide rod 21 in pilot hole 15 is protruded into 3 activity of spring, so that sealing-plug 2 is made straight line fortune by the cooperation of guide rod 21 and pilot hole 15
It is dynamic, it is additionally provided with the positioning convex platform 22 that a circle is located in protective case 6 on guide rod 21, one end of spring 3 is against on positioning convex platform 22,
The other end is against in mounting base 13, and the outer diameter of positioning convex platform 22 and the internal diameter clearance fit of protective case 6 can also play limitation sealing
Fill in 2 effects for linear motion.
Spring 3, guide rod 21 are placed in valve body 1 by the present invention, and the coil 4 of electromagnetic mechanism is wrapped on valve body 1, solenoid valve
100 volume is more small and exquisite, suitable for applying the delivery device of the cleaning equipments such as washing machine, dish-washing machine.It can lead to when design
It crosses the volume for lowering spring conductor rod structure and increases the area of piston end surface and the volume of electromagnetic core, reach piston stress
Uniform effect, while the area of import 11 can also be increased, reduce a possibility that blocking for a long time using rear solenoid valve 100.
As shown in figure 4, the invention also provides the delivery device for using above-mentioned solenoid valve, including depository dish 7 and flushing box
8, depository dish 7 has at least one fluid hole, and each fluid hole is each equipped with the above-mentioned solenoid valve for switching its on off operating mode,
The import of solenoid valve and fluid hole are tightly connected, and rinsing box 8 has inlet opening and tap 81, and inlet opening connects cleaning equipment
Main inlet valve, main inlet valve are connected with tap water pipe line, and tap 81 connects the working chamber in cleaning equipment, rinse on box 8 also
Equipped with the one-to-one inlet opening of solenoid valve 100, the corresponding inlet opening in the outlet 12 of each solenoid valve 100, which seals, to be connected
It connects, fluid hole is located at a side bottom of depository dish 7, and the inner chamber bottom surface of depository dish 7 is guide face, and the height of guide face is by far from out
One end of fluid apertures is gradually decreased to the other end close to fluid hole, and the position for rinsing box 8 is lower than depository dish, and solenoid valve 100 is opened
When depository dish 7 in detergent flowed under the effect of gravity along water conservancy diversion towards fluid hole, flowed by solenoid valve 100 and inlet opening
It rinses in box 8.
Preferably, inlet opening is set to the one end for rinsing box 8, and tap 81 is set to the other end for rinsing box 8, inlet opening arrangement
It is arranged between inlet opening and tap 81.After detergent, which flows to, rinses box 8, inlet opening starts to wash by water into flushing box 8, water
The detergent successively rinsed by inlet opening with abundant dissolution in box 8 is flowed, detergent passes through tap 81 after mixing with water dissolution
The working chamber for being sent to cleaning equipment participates in washing process.
Further, it is also equipped with electric hot plate in the inner chamber bottom surface of depository dish 7, maintains to wash in depository dish by electric hot plate
The temperature of agent is in preset temperature always, and preset temperature value can be set according to the corresponding optimum activity temperature of different detergent
It sets, depository dish 7 is preferably made of thermal insulation material, to prevent the temperature of detergent in depository dish 7 from being influenced by environment.In temperature one
In the case where fixed, detergent it is viscous set coefficient be it is the same, when keeping identical bore and tilt angle, due to detergent
It is viscous set that coefficient is relatively high, and the limited height of entire depository dish 7, thus in depository dish 7 detergent amount how much convection current
The influence of speed can be ignored, therefore the flow velocity of detergent is certain, and wash when single fluid hole opening solenoid valve 100
The injected volume of agent can be calculated simply by flow velocity multiplied by the time.
Delivery device is additionally provided with control module, and all solenoid valves 100 are connect with control module, and control module is guaranteeing often
Under the premise of the release time equal length of secondary 100 putting detergent of opens solenoid valve is consistent, judged according to the injected volume of detergent
100 quantity of solenoid valve for needing to open, for example, when injected volume is larger, open two or three solenoid valves 100 to dispensing
Time, when injected volume is smaller, only one solenoid valve 100 of unlatching to release time can meet dispensing to meet injected volume
Amount.Delivery device is applied when on washing machine, and washing machine weighs to the clothes in working chamber, according to the Gravity calculation of clothes
Injected volume, 100 quantity of solenoid valve that control module needs to open further according to injected volume judgement, improves and launches efficiency.
The invention also provides cleaning equipments, and including above-mentioned delivery device, cleaning equipment is washing machine.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
