A detailed description of the first integrated module (i.e., the integrated solenoid valve structure) will be provided with reference to fig. 4 to 6. The electromagnetic valve integrating the pressure switch into a whole comprises a first water inlet channel 41, a shell 40 and a first water outlet channel 42, wherein the shell 40 comprises a middle area 40a, and an electromagnetic valve area 40b and a pressure switch area 40c which are respectively arranged at two sides of the middle area 40a, the middle area 40a comprises a first cavity 43a and a second cavity 43b, and the second cavity 43b can be blocked or communicated with the first cavity 43a under the condition that the electromagnetic valve is powered off or powered on; a first diaphragm 44 is disposed between the middle area 40a and the pressure switch area 40c, a third cavity 43c is formed between the first diaphragm 44 and the middle area 40a, and the third cavity 43c is communicated with the first cavity 43 a; a push rod 45, a first spring member 46 and a micro-switch 47 are further disposed in the pressure switch area 40c, the push rod 45 and the third chamber 43c are disposed on two sides of the first diaphragm 44, the first spring member 46 is disposed between the push rod 45 and the micro-switch 47, and the micro-switch 47 further includes a connection line 47a extending from the pressure switch area 40 c. The solenoid valve area 40b is disposed on the other side of the intermediate area 40a relative to the pressure switch area 40c, a second diaphragm 48 is disposed between the solenoid valve area 40b and the intermediate area 40a, and a magnet 49, a second spring member 50 and a solenoid valve magnet 51 are disposed in the solenoid valve area 40b, wherein the magnet 49 is disposed between the second diaphragm 48 and the second spring member 50, and the solenoid valve magnet 51 is disposed around the outer periphery of the second spring member 50 and the magnet 49.

Thus, if the micro switch 47 is normally open, during operation, water flows into the first cavity 43a and the third cavity 43c from the first water inlet channel 41, the first diaphragm 44 is jacked up under the action of water pressure to cause deformation of the diaphragm, so that the push rod 45 can overcome the resistance of the first spring member 46 and the micro switch 47 to move the same, when the water pressure reaches a set value for closing the pressure switch, the micro switch 47 is closed, the circuit is conducted, and the electromagnetic valve is powered on; at this time, the solenoid magnet 51 in the solenoid valve area 40b generates a magnetic force to attract the magnet 49, and the magnet 49 compresses the second spring member 50 to lose the pressure on the second diaphragm 48, so that the water flows into the second chamber 43b from the first chamber 43a and finally is discharged from the first water outlet passage 42. Similarly, if the microswitch 47 is of a normally closed type, the water flows from the first water inlet channel 41 into the first cavity 43a, the second cavity 43b and the third cavity 43c, and flows from the second cavity 43b to the first water outlet channel 42; when the water pressure of the third cavity 43c reaches a certain value, the first diaphragm 44 is jacked up under the action of the water pressure to cause the deformation of the diaphragm, so that the push rod 45 can overcome the resistance of the first spring piece 46 and the microswitch 47, when the water pressure continues to increase to reach a set value of the disconnection of the pressure switch, the microswitch 47 is disconnected, the circuit is disconnected, and the electromagnetic valve is in a power-off state; at this time, the solenoid valve magnet 51 in the solenoid valve area 40b loses magnetic attraction to the magnet 49, the magnet 49 is pushed open by the second spring member 50 and abuts against the second diaphragm 48 to press the diaphragm, at this time, the water flow cannot enter the second cavity 43b from the first cavity 43a to block the water flow, and the first water outlet channel 42 stops water outlet. It is readily appreciated that the pressure switch may be either a high pressure switch or a low pressure switch. Like this, this collect pressure switch in solenoid valve structure of an organic whole carries out highly integrated modular design with pressure switch and solenoid valve, and the equipment is simple, simplifies the required reservation mouth of water route board die sinking, can very effectively reduce complete machine equipment manual work, man-hour and cost, has very high economic benefits, has satisfied customer's demand.
