The inflow tube 12 and the outflow tube 13 are simultaneously disposed in the tube body 11, the nozzle of the inflow tube 12 and the nozzle of the outflow tube 13 are simultaneously communicated with the chamber 101, and the connection structure is disposed in the inflow tube 12 and the outflow tube 13. When the external fluid enters the tube 11 through the inlet tube 12, the fluid enters the cavity 101 and then flows out through the outlet tube 13. The connecting structure 14 includes a fixing member 141 and an engaging member 142. The fixing member 141 is disposed on one of the outlet pipes 13, the engaging member 142 is disposed on the inlet pipe 12, so that when the outlet pipe 13 is inserted into the inlet pipe 12, the fixing member 141 and the engaging member 142 are engaged, and the outlet pipe 13 is fixed in the inlet pipe 12, thereby connecting the outlet pipe 13 and the inlet pipe 12 together, and achieving the purpose of quickly connecting the outlet pipe 13 and the inlet pipe 12.

The solenoid assembly 20 is provided in the pipe body 11 so as to be able to control opening and closing of the outflow pipe 13 to which the mount 141 is not connected.

In use, for example, three of said solenoid valves can be connected in series and distributed side by side to each other under the action of said connection structure 14. Specifically, the outflow tube 13 of the former solenoid valve is inserted into the inflow tube 12 of the latter solenoid valve, and the two adjacent solenoid valves are stably connected by the connecting structure 14. Fluid flows from the inlet pipe 12 of the first solenoid valve to the outlet pipe 13 of the last solenoid valve, and the conduction state of one of the outlet pipes 13 and the chamber 101 can be controlled under the control of the solenoid coil assembly 20. Therefore, in the case where three solenoid valves are connected in series, three solenoid coil assemblies 20 can control the conduction state of at least three outflow pipes 13, and whether the three outflow pipes 13 and the chamber 101 are conducted or not is independently controlled. Through connection structure 14 can link two the solenoid valve together fast, the operation of being convenient for, and a plurality of the solenoid valve is convenient for centralized processing management and control.

It should be noted that the solenoid assembly 20 does not affect the conduction state of the outflow tube 13 to which the fixing member 141 is connected, and the solenoid assembly 20 can only control the conduction state of the outflow tube 13 to which the fixing member 141 is not connected.

The solenoid assembly 20 includes a coil 21 and a magnetic spool 22. The coil 21 is disposed on top of the valve body assembly 10. The magnetic valve core 22 is movably disposed inside the cavity 101, and the magnetic valve core 22 is located at a pipe orifice of the outflow pipe 13 which is not connected with the fixing element 141, so as to achieve the purpose of controlling the conduction state of the outflow pipe 13 which is not connected with the fixing element.

The outflow pipe 13 is implemented in two, and the outflow pipe 13 to which the fixing member 141 is connected is defined as a horizontal outflow pipe 131, and the other outflow pipe 13 is defined as a vertical outflow pipe 132. The inflow pipe 12 is parallel to the horizontal outflow pipe 131. The horizontal outflow pipe 131 functions to conduct two adjacent solenoid valves, so that liquid can flow inside the solenoid valves. The vertical outflow pipe 132 functions to discharge the liquid in the chamber 101.

The solenoid assembly 20 is used to control the conduction state of the vertical outflow tube 132 and the chamber body 101.

Therefore, when a plurality of solenoid valves are connected in series, because the inlet pipe 12 and the horizontal outlet pipe 131 are both horizontal, the plurality of solenoid valves are linearly distributed side by side, so that the vertical outlet pipe 132 of each solenoid valve can be clearly distinguished easily, an operator can conveniently distinguish the outlet pipe of each vertical outlet pipe 132, and each solenoid valve is provided with the solenoid coil assembly 20, so that each vertical outlet pipe 132 can be controlled independently.

The pressing portion 1422 is movably disposed on the sidewall of the inflow tube 12, the pressing portion 1422 abuts against the elastic member 1421, and the pressing portion 1422 is close to one end of the elliptical hole 1401. When the pressing portion 1422 is pressed by the outside, the shape of the elliptical hole 1401 can be changed. Specifically, when the elastic member 1421 is not pressed, the fixture 141 cannot pass through the elliptical hole 1401, and when the elastic member 1421 is pressed, the fixture 141 can pass through the elliptical hole 1401. Therefore, before the horizontal outflow pipe 131 is inserted into the inflow pipe 12, the pressing portion 1422 is pressed to change the shape of the elliptical hole 1401, so that the horizontal outflow pipe 131 can be inserted into the inflow pipe 12, the pressing of the pressing portion 1422 is stopped, the elastic member 1421 returns to the initial state, the horizontal outflow pipe 131 and the inflow pipe 12 are connected together, and when disassembly is required, the pressing portion 1422 is pressed again, so that the horizontal outflow pipe 131 can be taken out of the inflow pipe 12, and the horizontal outflow pipe 131 and the inflow pipe 12 can be detachably connected.
