(3) the swing rod 6, the push rod 5, the spring 54 and the like are sequentially placed into the bearing barrel 4, the locking ring 7 is sleeved at the bottom of the bearing ring 12 of the valve seat 1, and the bearing barrel 4 is locked at the bottom of the valve seat 1;

(4) finally, the locking ring 7 is locked on the water outlet pipe Q1, and the assembly is completed.

The dynamic structure and use of the first embodiment of the present invention are as follows:

referring to fig. 7, when the embodiment of the present invention is not operated, the swing rod 6 is kept in a vertical state, the push rod 5 moves down under the action of the spring 54 to abut against the swing rod 6, and the valve post 3 moves down under the action of gravity, water pressure and the spring 39, so that the water seal 331 presses against the valve 14 of the valve seat 1 to form an open-close state; at this time, the pawl pin 361 of the locking pawl 36 is located at the bottom of the self-closing section 241 of the P-shaped multi-section positioning slot 24 (as shown in fig. 4).

Referring to fig. 8, when the swing rod 6 is triggered to make a micro swing, one side of the driving disk 62 can abut against the bearing surface 41 of the bearing cylinder 4 to form a fulcrum, and the other side of the driving disk lifts along with the swing rod 6 in a micro arc, so as to lift the push rod 5 and push the valve post 3 to rise, so that the throttling part 32 and the water seal 331 of the valve post 3 slide away from the valve 14 in a micro amount, and therefore, water can flow out from the water outlet 42 of the bearing cylinder 4 through the valve 14 in a micro amount for use; at this time, the claw pin 361 of the spool 3 is located above the self-closing section 241 of the multi-stage positioning slot 24 and does not slide out of the self-closing section 241, so that when the swing rod 6 is released, the spool 3 can be pushed back to the position by gravity, water pressure and the elastic force of the spring 39, the valve 14 is rapidly closed "automatically", and the state shown in fig. 7 is recovered.

Referring to fig. 9 and 10, when the swing rod 6 is triggered to swing slightly, the driving disc 62 can also jack up the push rod 5 and push the valve stem 3 to rise, so that the throttle portion 32 and the water seal 331 slide away from the valve 14 slightly, and the water outlet 42 can generate a small amount of water (slightly larger than the above-mentioned trace amount) for supplying water; at this time, the claw pin 361 located in the multi-stage positioning slot 24 has slid out of the self-closing stage 241, as shown in fig. 4, i.e. slid over the non-return tooth a, and enters the small opening stage 242, so that when the swing lever 6 is released (as shown in fig. 10), the claw pin 361 will be positioned on the non-return tooth a at the bottom of the small opening stage 242, and cannot be moved back down, so that the valve column 3 will be positioned by being pulled by the latching claw 36, and will be kept in the small water supply state of "small opening".

Referring to fig. 11, when the touch swing rod 6 swings in a middle arc, the push rod 5 and the valve post 3 may be lifted up to make the water outlet 42 generate a middle water amount for supplying water; at this time, the claw pin 361 located in the multi-stage positioning groove 24 slides into and is positioned in the middle opening stage 243, and cannot move down to return, so that the spool 3 is pulled and positioned by the catch claw 36, and is kept in the middle water supply state of "on".

Referring to fig. 12, when the swing rod 6 is triggered at the maximum radian, the push rod 5 and the valve post 3 are also jacked up, so that the water outlet 42 generates the maximum amount of water for supplying water; at this time, the claw pin 361 located in the positioning groove 24 is slid into and positioned in the large opening section 244, and thus the spool 3 is pulled by the catching claw 36 to be maintained in the "large opening" medium water supply state.

Referring to fig. 10 and 13, when the swing rod 6 is triggered to position the valve post 3 at the small opening section 242, the middle opening section 243 or the full opening section 244, and the push rod 5 and the swing rod 6 are retracted (as shown in fig. 10), if the valve 14 is to be closed, the swing rod 6 is triggered again in a proper amount, the drive disk 62 may eccentrically jack up the push rod 5, so that the top 51 of the push rod 5 slightly eccentrically bites the support tube 31 to push the valve post 3 to move upward, and the claw pin 361 in the multi-stage positioning slot 24 slides upward into the releasing section 245, so that when the swing rod 6 is released, the claw pin 361 slides back to the self-closing section 241 from the releasing section 245, so that the valve post 3 can automatically return to rapidly close the valve 14 by gravity, water pressure and the elastic force of the spring 39, and the state shown in fig. 7 is restored.

From the above description, when the swing rod 6 is touched slightly, the instant on-off action of small water amount can be generated, and the swing rod 6 is touched with proper amount, so that the faucet can be opened and supplied with proper amount of water, when the faucet is touched with full amount, the maximum amount of water is generated, and when the faucet is to be closed, the faucet can be closed quickly as long as the swing rod 6 is touched with middle amount twice, so that the use is simpler and more convenient; furthermore, the swing rod 6 is arranged on the water outlet, so that when water is taken, the swing rod 6 can be directly touched by a teacup or a water ladle without being held by hands, and the swing rod is washed by clear water at any time and cannot be polluted, so that the water-saving and health-care water-saving device meets the requirements of overall sanitation and has industrial utilization value.

Referring to fig. 14, 15 and 16, a swing control type multi-stage faucet switch according to a second embodiment of the present invention is shown, which is configured such that a ratchet assembly 8 for one-way stopping is axially disposed on a valve stem 3, and a positioning tooth portion 24A is longitudinally formed on an inner wall of a guide seat 2 on an axial side of the valve stem, so as to cooperate with the ratchet assembly 8 to perform positioning operation at a predetermined vertical height position. As shown in fig. 14, the ratchet assembly 8 is formed by a pair of left and right shaft brackets 81, 82 which are coupled to each other by a shaft 81A, a spring 83 and a ratchet 84 are inserted into the shaft 81A, as shown in fig. 15 and 16, the spring 83 is fixed to the shaft brackets 81, 82 at both ends thereof, so that the ratchet 84 is prevented from being reversed in a direction toward the plurality of positioning teeth 24A by a reaction force of torsion in a radial direction toward a ventral side of the spring 83, and thus the same stepwise positioning effect as the first embodiment can be achieved. Other installation operation procedures are the same as those of the first embodiment, and therefore are not described herein.
