Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention; based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1, 2, and 3, a three-way valve includes a valve body 1, an air channel 7 penetrating through the valve body 1 from top to bottom is disposed in the middle of the valve body 1, a first valve port 2, a second valve port 6, and a third valve port 9 communicated with the air channel 7 are disposed on the valve body 1, a control valve core 10 is disposed in the air channel 7, a magnetic block I8 and a magnetic block II11 are disposed at the top and bottom ends of the control valve core 10, a switch connecting rod 13 is disposed at the bottom of the magnetic block II11, a sealing block 12 is disposed at the bottom of the air channel 7, the switch connecting rod 13 extends out of the air channel 7 from a through hole in the middle of the sealing block 12, an installation groove 15 is disposed on the outer side of the valve body 1, a magnet I16, a magnet II17, and a magnet III18 are installed in the installation groove 15, a magnet I16 and a magnetic block 829.

As shown in fig. 4, the water discharger body a1 is communicated with a water inlet pipe a2, a water inlet valve a6 with one end hinged to the water inlet pipe a2 is arranged at the outlet of the water inlet pipe a2, the water inlet pipe a2 is connected with a first valve port 2 of a three-way valve a5 through a leather hose Ia4, a third valve port 9 of the three-way valve 5 is communicated with the inside of the water discharger body a1, and a second valve port 6 of the three-way valve a5 is connected with an atmosphere communication port a13 on the water discharger body a1 through a leather hose IIa 12; a floating ball device a8 is arranged in the water discharger body a1, a floating ball device a8 is fixed on a guide device, the top end of the guide device is connected with a switch connecting rod 13 of a three-way valve a5, a water outlet a11 is arranged at the bottom of the water discharger body a1, and a water outlet valve a10 is arranged on the water outlet.

After water is fed into the water discharger body a1, the floating ball device a8 moves upwards under the action of buoyancy and pushes the switch connecting rod 13 to jack up upwards, when the attraction force of the magnetic block I8 and the magnetic block II11 with the magnet I16 and the magnet III5.18 reaches a limit, the control valve core 5.10 is quickly lifted up under the action of the magnetic force, after the control valve core 5.10 rises to a peak, the second valve port 5.6 is communicated with the third valve port 5.9, a connecting channel between the first valve port 5.2 and the third valve port 5.9 is closed, and then the water inlet valve a6 is closed through air pressure difference.
