Described water box 4 has water inlet A 401, water inlet B 402, water inlet C403, water inlet D404, intake chamber 405, water-supplying chamber 406 and delivery port 407, water inlet A 401 links to each other with described intake chamber 405, water inlet B 402 links to each other with delivery port 407, and water inlet C403, water inlet D404 are connected with water-supplying chamber 406;
The outlet A102 of described electromagnetic water inlet valve 1 and outlet B103 link through the water inlet A 401 and the water inlet B 402 of seal and described water box 4, the inflow entrance B30122 of described Perfected electromagnetic metering valve 3 and the delivery port of water box 4 407 link through seal 7, the water inlet C403 of described water box is connected through seal 9 with the floss hole of described Perfected electromagnetic metering valve 30112, described water box water inlet D404 is connected through water pipe 8 with the delivery port 407 of described Perfected electromagnetic metering valve, and the outlet 201 of described liquid detergent groove 2 links to each other through piping 10 with the inflow entrance A30111 of described Perfected electromagnetic metering valve.Described seal can be the O shape rubber ring of general standard, also can be special rubber seal.
The outlet 201 of liquid detergent groove 2 in height is in the position that is higher than Perfected electromagnetic metering valve 3 inflow entrance A30111, can flow into the measuring room 3013 of Perfected electromagnetic metering valve to guarantee the liquid in the liquid detergent groove under the deadweight effect.
The position of the flow export 30123 of Perfected electromagnetic metering valve 3 keeps the water inlet D404 a little more than water box 4.
The following describes the input action of liquid detergent:
Under the A-stage, solenoid 306 outages of Perfected electromagnetic metering valve 3, the rebound effect that movable core 302 is subjected to spring 305 with piston cap 303 wedges on valve seat A30113, cleaning solution in the liquid detergent groove 2 can not enter measuring room 3013 by pipeline 10, be in closed condition, the valve seat B30124 of Perfected electromagnetic metering valve is in open mode makes the water in the measuring room 3013 be discharged into the water-supplying chamber 406 of water box 4 by flow export 30123, and the effect that ball sealer 308 is conducted oneself with dignity breaks away from the valve seat C30114 of Perfected electromagnetic metering valve.
When needing to throw in washing agent, give solenoid 306 energisings of Perfected electromagnetic metering valve, movable core 302 is moved to secured core 304 by electromagnetic attraction, piston cap 303 is lifted off a seat A30113 and is located on the valve seat B30124, the cleaning solution pipeline is communicated with measuring room 3013 and outlet pipeline (delivery port) and measuring room 3013 are closed, liquid detergent flows into the measuring room 3013 of Perfected electromagnetic metering valve under the deadweight effect, the spool 3071 of check valve 307 contacts with check valve body 3073 under the effect of spring 3072, make measuring room 3013 on inflow entrance B30122 direction, be in sealing state, liquid levels in the measuring room raises and forces ball sealer 308 to move up under buoyancy, when liquid level was elevated to a certain degree, ball sealer 308 made measuring room 3013 and floss hole 30112 be in isolation.Even movable core 302 kept the state of being attracted and can not continue to flow into this moment.
The space of supposing measuring room 3013 is 10cc, the mobile difference of different liquid detergents is bigger, cleaning solution such as good fluidity is full of measuring room needs 3 seconds, and the cleaning solution of mobile difference may need 6 seconds, for the poorest cleaning solution that flows also can accurately be measured, may be made as the conduction time of solenoid 306 8 wonderfully,, thereby guarantee the precision of metering even the cleaning solution of good fluidity also can only flow into 10cc like this.
After metering is finished, solenoid 306 outage, movable core 302 resets, and valve seat A30113 is in and closes and valve seat B30124 is in open mode.Electromagnetic water inlet valve 1 energising, running water enters water box 4 by electromagnetic water inlet valve, and process water box delivery port 407 enters the inflow entrance B30122 of Perfected electromagnetic metering valve 3, the counter-force that the check valve 307 spools 3071 suffered hydraulic pressure of Perfected electromagnetic metering valve overcome spring 3072 makes check valve open to measuring room 3013 directions from inflow entrance B30122, running water enters measuring room and flows to flow export 30123 through valve seat B30124, and enters the water-supplying chamber 406 of water box through the water inlet D404 of piping and water box.Lasting energising a period of time of electromagnetic water inlet valve can fully be punched into water box the inside to the cleaning solution in the Perfected electromagnetic metering valve measuring room.
Electromagnetic water inlet valve outage after flushing is finished, electromagnetic water inlet valve 1, check valve 307 resets, C403 applies atmospheric pressure to ball sealer 308 by water box water inlet, and the water of measuring room interior 3013 flows to water box water-supplying chamber 406 through valve seat C30114 and is lower than valve seat C30114 up to the liquid level of measuring room under the effect of water-head.
So such circulation can be thrown in the liquid detergent of a measuring room volume (such as 10cc) to water box water-supplying chamber, in the time of need throwing in more volume, repeatedly repeats the input that above-mentioned circulation can realize measuring room volume integer multiple.
