The valve of this embodiment is installed as follows:

as shown in fig. 15 and 16, first, the ratchet holder 32 is inserted into the housing 1 from the open end of the housing 1 and protrudes through the seventh hole 13 of the housing 1. Then, the movable ratchet 9 is hung on the key 8, and the two are mounted on the ratchet seat 32. Next, the transmission gear 6 is mounted on the inner seat 31 through the pin 7.

Subsequently, the movable ceramic piece 52 and the movable ceramic piece holder 51 of the plugging member 5 are connected to each other by rotation stopping, and then are inserted into the inner cavity of the fourth casing 315 of the inner holder 31. And the second rack portion 512 is brought into engagement with the transmission gear 6. Finally, after the static ceramic piece seat 21 and the static ceramic piece 22 of the base 2 are connected in a rotation stopping manner, the static ceramic piece 22 is attached to the movable ceramic piece 52, and then the static ceramic piece seat 21 is clamped at the opening end of the shell 1 to be installed.

The valve of this embodiment is used as follows:

by pressing and releasing the key 8, the bouncing mechanism is pressed to drive the sliding piece 4 to stop at the first position or the second position. The movement process of pressing the bouncing mechanism in this embodiment is similar to the structure of the ball-point pen button 8, and is not described in detail herein.

As shown in fig. 15 to 17, in the process that the sliding member 4 slides and stops at the first position, the driving gear 6 is driven to rotate counterclockwise, and the driving gear 6 drives the blocking member 5 to move rightward, so that the water passing groove 522 is not communicated with the water inlet.

As shown in fig. 18 to 20, in the process that the sliding member 4 slides and stops at the second position, the transmission gear 6 is driven to rotate clockwise, the transmission gear 6 drives the blocking member 5 to move leftwards, so that the water passing groove 522 is communicated with the water inlet, and at the moment, water is discharged from the water outlet.

Since the transmission gear 6 is engaged with both the first rack portion 413 of the sliding member 4 and the second rack portion 512 of the blocking member 5, the transmission gear 6 is driven to rotate to drive the blocking member 5 to slide in the process that the sliding member 4 slides to the first position or the second position, so that the water passing groove 522 is communicated or not communicated with the water inlet. The driving force of the sliding piece 4 is transmitted through the transmission gear 6 and reversed, so that the plugging piece 5 can move in the direction perpendicular to the pressing direction to break or break the communication between the water inlet and the water outlet.

Since the water inlets in this embodiment include the cold water inlet and the hot water inlet, as shown in fig. 15 to 17, when the slider 4 is parked at the first position, the water passing groove 522 is not communicated with both the cold water inlet and the hot water inlet. As shown in fig. 18 to 22, when the slider 4 is at rest in the second position, the water passing groove 522 communicates with the cold water inlet and the hot water inlet, and the flow of water out of the water outlet is warm water in which the cold water and the hot water are mixed. At this time, the blocking piece 5 is rotated by rotating the rotating seat 3, so that the water passing area between the cold water inlet and the water passing groove 522 and the water passing area between the hot water inlet and the water passing groove 522 can be adjusted, and the temperature of the water flow flowing out of the water outlet can be adjusted according to the requirement of the user. By rotating the rotatable base 3 clockwise as shown in fig. 21, the through-water tank 522 is made to communicate only with the cold water inlet, which is now full cold water outlet. Fig. 22 shows that by rotating the rotatable seat 3 counterclockwise, the through-water tank 522 is only in communication with the hot water inlet, and now full hot water is discharged.

The mixed cold water of push type that has on the market and hydrothermal valve, the majority is through setting up the guide's formula only to lead water switch and realize switching on and off water, be equipped with in this kind of case with the muddy water chamber that hot water inlet and cold water inlet all communicate, cold water and hot water flow to the delivery port again after mixing the water chamber and mixing, guide's formula only leads water switch and mixes the opening and closing of chamber and the intercommunication realization valve of delivery port through the break-make, this kind of valve is owing to no matter the valve is opened or is closed, hot water inlet and cold water inlet all communicate with muddy water chamber, scurry water easily. In the prior art, the water inlet ends of a hot water inlet and a cold water inlet are provided with one-way valves to prevent water from flowing, but when the pressure difference between hot water and cold water is too large, the one-way valves are easy to lose effectiveness. The valve of this embodiment presses the bounce mechanism through the setting, drives slider 4 through pressing button 8 and berths with primary importance and second place, as shown in fig. 17, and shutoff piece 5 shutoff hot water inlet and cold water inlet have both realized opening and close of valve through the mode of pressing when slider 4 is in the primary importance, also can prevent the problem of scurrying water simultaneously.
