5. A method of using a mixing valve for preventing sudden water spray from a bathroom shower as claimed in any one of claims 2 to 4, comprising the steps of:
s1, in an initial state, the bottom end of a sealing column is inserted into a second water outlet, a second water diversion port is positioned in the second water outlet, the second water diversion port is blocked, and the first water diversion port is opened and communicated with a water flow channel; when the water flow device is used, the handle is lifted upwards, the handle drives the valve rod to move upwards, and then the lifting rod is driven to move upwards, so that the stop plate is driven to lift upwards, the water flow channel is opened, and water flows out through the first water diversion port and is discharged downwards through the first water outlet;
when the lifting rod moves upwards, the second rack moves upwards along with the lifting rod, the ratchet wheel is driven to rotate clockwise, the pawl and the ratchet wheel are in the forward direction when the ratchet wheel rotates, the pawl rotates around the pin shaft when the ratchet wheel rotates, and the pawl and the second gear rotate relatively, so that the second gear cannot rotate when the ratchet wheel rotates, the ratchet wheel idles, at the moment, the position of the sealing column keeps the initial state, water flow can only be discharged downwards through the first water outlet, and water flow can be prevented from being sprayed out from the second water outlet through the shower head;
s2, when the shower head is needed, firstly lifting the handle, and moving upwards through the valve rod, the lifting rod and the stop plate, so that the water flow channel is opened; then, the lifting rod is lifted up, and the friction force between the sealing column and the partition plate is larger than the elastic force of the first spring; therefore, the first spring is firstly lengthened, the sealing column is relatively kept still, the lifting rod moves upwards relative to the sealing column, and after the lifting rod moves upwards, the first rack moves rightwards under the action of the second spring and is not meshed with the first gear any more because the bottom of the lifting rod is in a conical design; along with the continuous upward movement of the lifting rod, when the convex block is contacted with the top surface of the angle plate, the lifting rod drives the angle plate to move upward, and then drives the sealing column to move upward together, at the moment, the first water diversion port and the second water diversion port move upward, and when the first water diversion port passes through the water flow channel, the second water diversion port is communicated with the water flow channel, at the moment, water can only flow to the second water outlet through the second water diversion port, water flow can enter the shower head, and the shower head normally uses water; after water is introduced, the lifting rod is loosened, and moves downwards under the action of the elastic force of the first spring, at the moment, the conical structure at the bottom end of the lifting rod also moves downwards, the first rack is pushed leftwards, and the first rack is meshed with the first gear again;
after the shower water is finished, the handle is pressed downwards, the valve rod, the lifting rod and the stop plate move downwards, the water flow channel is closed, the second rack drives the ratchet wheel to rotate anticlockwise in the process, the pawl and the ratchet wheel are reversely meshed at the moment, the ratchet wheel drives the pawl to rotate, the second gear is driven to rotate, the second gear drives the first gear to rotate, the first rack is meshed with the first gear at the moment and can be driven to move downwards, the sealing column is driven to move downwards, the sealing column returns to the initial state, the first water diversion port is communicated with the water flow channel again, the second water diversion port is blocked, and water is discharged from the first water outlet when the handle is opened next time.
