As shown in Figure 1 and Figure 6, a sensory water temperature memory type automatic rotary water-saving faucet of the present invention includes a casing 1, a handle 2 arranged on the upper part of the casing 1, a lifting mechanism 3 arranged on the lower part of the handle 2, and a 1 Internal piston top cover 4, two-way water inlet valve 5, water outlet 6, temperature control knob 7, elastic connection mechanism 8, self-locking mechanism 9 for fixing the position of temperature control knob 7 and unlocking temperature control knob 7 Position unlocking mechanism 10; wherein, the upper end of the piston top cover 4 is provided with a hollow cover 11, and the top of the hollow cover 11 is connected to the lifting mechanism 3; the elastic connection mechanism 8 is connected to the hollow cover 11 and the temperature control knob 7; The temperature control knob 7 includes a knob adjustment plate 12, the upper part of the knob adjustment plate 12 is provided with an upper cylindrical structure 13, and the lower part is provided with a lower cylindrical structure 14, and the lower cylindrical structure 14 extends into the center of the two-way water inlet valve 5 , to form a valve flow, and the front of the housing 1 is provided with a gap, which is convenient for rotating the knob to adjust the disc 12 .

As shown in Figure 4, Figure 5, Figure 7 and Figure 8, the present invention adjusts the water temperature through the temperature control knob 7, locks the temperature control knob 7 by the self-locking mechanism 9, and controls the water volume and water temperature of the water outlet by lifting or rotating the handle 2 . When the handle 2 is lifted up and the water tap is turned on, the unlocking mechanism 10 takes effect, and the adjustment of the water temperature is not restricted at this time. The upper cylinder structure 13 of the temperature control knob 7 is engraved with a chute, the chute is formed by connecting the vertical chute 15 and the lateral chute 16, and two arc-shaped grooves 17 are symmetrically arranged on the knob adjustment plate 12, The hollow cover 11 passes through the arc-shaped groove 17, there is a slight gap between the two, and the mutual rotation is not affected.

As shown in Figure 3, the two-way water inlet valve 5 of the present invention comprises a rotary piston 18, a hot water inlet pipe 19, a cold water inlet pipe 20 and a mixed water outlet 21. The upper part of the rotary piston 18 is rigidly connected to the piston top cover 4, The lower cylinder structure 13 of the temperature control knob 7 extends into the center of the rotary piston 18 of the two-way water inlet valve 5, and there is a fan-shaped cavity between the lower cylinder structure 13 and the rotary piston 18 to form a water outlet channel. Cold and hot water flow into the two-way water inlet valve 5 oppositely. The side wall of the rotary piston 18 is provided with two water inlet holes, which are respectively a hot water inlet hole 22 and a cold water inlet hole 23. The cold and hot water flow from the water inlet pipe 19 . The central angle of the opening range of the water inlet holes 22 and 23 is consistent with the angle at which the handle 2 rotates to the left or right. When reaching the highest position, the water inlet holes 22, 23 are at the same height as the center of circle of the cold and hot water inlet pipes 19, 20. When the handle 2 is fully turned to one side, the water inlet pipe on the opposite side is completely closed, and when the handle 2 is lifted to the highest position, the total water output is the largest. The proportion of cold and hot water flowing into the two-way water inlet valve 5 and the total amount of water can be controlled by rotating and lifting the handle 2 . In the default state, lift the handle 2 to turn on the faucet. At this time, the position of the rotary piston 18 makes the amount of hot and cold water flowing into the water inlet valve equal. By rotating the temperature control knob 7, the water temperature can be adjusted to a comfortable state as the preset water temperature. After the end, the self-locking mechanism 9 takes effect. At this time, at any position, press the handle 2 to close the faucet, and the handle 2 will automatically rotate to the preset temperature position under the action of the elastic connection mechanism 8, which is convenient for subsequent use.

As shown in Figure 11, the self-locking mechanism 9 of the present invention is used to fix the position of the temperature control knob when in use, and includes a button 24, a spring 25, a locking pin 26, a fixing seat 27 and a connecting rod 28, and the fixing seat 27 consists of three parts. Parts are used to control the movement directions of the locking button 24, the connecting rod 28 and the locking pin 26 respectively. The locking button 24 is connected with the fixing seat 27 by a spring 25 . The two ends of the connecting rod 28 are respectively connected with the locking button 24 and the locking pin 26, and the middle part of the connecting rod 28 is connected with the fixing seat 27, and the connecting rod 28 can rotate around the hinge point in the middle. The locking pin 26 can move back and forth in the fixed seat 27 . In the initial state, the spring 25 is under pressure, and the locking pin 26 is in contact with the adjusting disc 12 of the temperature control knob, and the position of the adjusting disc 12 is locked. After the button 24 is pressed, the locking pin 26 is driven by the connecting rod 28 to move backward. At this time, the temperature control knob 7 can be rotated left and right to adjust the water temperature preset value. After the setting is completed, the button 24 is released, and the locking pin 26 moves forward under the action of the spring 25 and the connecting rod 28 to realize the locking of the position of the temperature control knob 7 .

As shown in Figures 9-10, the elastic connection mechanism 8 of the present invention includes a steel ball 29, 30 with a diameter of 3 mm at each end and a spring 31 connecting the steel balls 29, 30, and one end of the steel balls 29, 30 at both ends is fixed to the hollow cover 11 In the inner wall, it does not move relative to the hollow cover 11, and the other end is embedded in the chute 15, 16 of the upper cylinder 13 of the temperature control knob 7, the steel ball 29, 30 can slide in the chute 15, 16, and the spring 31 There are two sets of assemblies with steel balls 29 and 30, which are symmetrically arranged on both sides of the upper column structure 13 of the temperature control knob 7. When the faucet is closed, since the position of the temperature control knob 7 has been locked by the self-locking mechanism 9, and its upper column structure 13 is fixed, the steel ball 29 in the chute 15 is restricted in the vertical chute 15. At this time, Due to the pulling force of the springs 31 on both sides, the rotation of the hollow cover 11 at the other end of the spring 31 is restricted, thereby also restricting the rotation of the handle 2 . And when lifting the handle 2, the lifting mechanism 3 drives the steel ball 29 in the cover body 11 and its inner wall to rise. The inner steel ball 30 can slide horizontally, the rotation of the hollow cover 11 at the other end of the spring 31 is no longer restricted, the rotation restriction of the elastic connection mechanism 8 to the hollow cover 11 is removed, and the water temperature can be freely adjusted by the rotating handle 2. When the handle 2 is pressed down at any position to the closed state, the steel ball 29 in the hollow cover 11 drops to the initial position, and the steel ball in the chute 16 slides down to the vertical chute 15 again under the tension of the spring 31 and its own gravity. At this time, the steel ball 29 Horizontal sliding is limited, so the springs 31 on both sides will make the hollow cover 11 automatically rotate, thereby driving the rotary piston 18 and the handle 2 to rotate to the preset temperature position.

The assembly sequence of the temperature control knob 7, the hollow cover 11 and the two-way water inlet valve 5 is shown in Fig. In the inside of the rotary piston 18, the top of the spool 14 passes through the circular hole at the top of the rotary piston 18, and the piston top cover 4 is fixed on the top of the rotary piston 18. Thereafter, the upper cylindrical structure 13 of the temperature control knob 7 is connected to the hollow cover 11 with the elastic connection mechanism 8, wherein the steel ball 30 that needs to be embedded in the chute 15, 16 is loaded from the bottom of the vertical chute 15. Then fix the upper cylinder structure 13 on the temperature control knob adjustment plate 12, and pass the lower part of the hollow cover 11 through the arc-shaped groove 17 reserved on the adjustment plate 12 at the same time. Then, the bottom of the hollow cover 11 is fixed on the piston top cover 4 . Finally, fix the lower cylinder structure (spool) 14 of the temperature control knob and the adjustment plate 12 of the temperature control knob. See Figure 13 for the assembly diagram.

As shown in Figure 2, the working principle of the present invention is as follows: cold and hot water flow into the rotary piston 18 through the cold and hot water inlet holes 22,23 respectively. When the handle 2 is lifted up to turn on the water tap, the unlocking mechanism 10 takes effect, and the steel ball 30 in the vertical chute 15 of the upper cylinder 13 of the temperature control knob is pulled into the lateral chute 16 . At this time, the movement of the steel ball 30 is not restricted by the spring 31 in the elastic connection mechanism 8 , and can roll freely in the lateral sliding groove 16 . Therefore, in this state, the embodiment of the present invention is consistent with the usage method of common hot and cold faucets. After the faucet is turned on, the lock button 24 can be pressed to release the locking of the temperature control knob 7 by the self-locking structure. At this time, the handle 2 adjusts the water temperature of the water outlet 6 of the faucet to a comfortable level, and rotates the temperature control knob adjustment plate 12. Turn the front pointer 32 of the adjustment dial to the mark position 33 and release the locking button 24, and the position of the adjustment dial is fixed. Thereafter, press the handle 2 at any position to close the faucet, the steel ball 30 in the lateral chute 16 will fall back into the vertical chute 15, the unlocking mechanism will fail, and the relative movement between the hollow cover 11 and the temperature control knob 7 will be elastically controlled. Constraints of the connecting mechanism 8. Since the temperature control knob adjustment plate 12 has been locked by the self-locking mechanism 9, the hollow cover 11 will rotate under the joint pulling action of the springs 31 at both ends, as shown in Figure 9(b). And the handle 2 is rigidly connected with the hollow cover 11 by the lifting mechanism 3, so the hollow cover 11 will drive the handle 2 to rotate together until the corresponding position of the set water temperature. When the water tap is turned on again later, the handle 2 is directly lifted up at the current position to obtain water flow at a suitable temperature. The embodiment of the present invention thus realizes the memory function to the water temperature.
