Description

Technical Field

[0002] A shower faucet is usually connected to cold water and hot water respectively and forms mixed water through a built-in thermostatic valve. The mixed water flows to a built-in switching valve and is connected to a handheld shower, overhead shower, spray gun shower or lower water outlet of the shower faucet through the switching valve.

[0003] Some electronic shower faucets on the market use solenoid valves as water circuit switches with manual thermostatic valves. Such shower faucets produce scale over time, which can easily cause valve core failure of the manual thermostatic valve. Such manual thermostatic valves usually use manual adjustment to set the water temperature, with poor thermostatic adjustment accuracy and inaccurate temperature. The valve core of such manual thermostatic valves usually uses a paraffin temperature bag type for temperature adjustment, and its telescopic length is limited, resulting in a relatively small water flow cross-section of the manual thermostatic valve. The temperature adjustment speed of the paraffin temperature bag valve core is slow, and the temperature is inaccurate, affecting the user experience. Summary of the invention

At this time, there are two groups of left and right coils in the valve head 713 of the solenoid valve part 71, among which the left end coil module is energized to generate a magnetic field, and the magnetic force of the magnetic field is greater than the elastic force of the second spring 714, which adsorbs the magnetic guide column 715 to move to the left, and drives the fifth sealing ring 716 to move to the left and compress the second spring 714, and the magnetic guide column 715 moves to the upper end of the valve head 713, the pulse information stops, and the magnetic field of the valve head 713 disappears. The first magnet 721 adsorbs the magnetic guide column 715 to prevent it from moving right. At this time, the pressure relief hole 701 in the center of the second valve seat 712 is opened, and the water cavity pressure at the left end of the diaphragm 82 flows from the water inlet holes on both sides of the second valve seat 712 to the pressure relief hole 701 for pressure relief, pushing the diaphragm 82 to move to the left, and the water outlet inside the second valve body 711 is opened, and water flows out from the water outlet of the second valve body 711.

[0092] When the water temperature needs to be adjusted, Figure 8 and Fig.10 As shown, touch the "+" and "-" on the right side of the glass panel 52. "+" is to adjust the temperature rise, "-" is to adjust the temperature rise. Each touch adjusts the water temperature by 1°C. If you need to adjust the temperature rise, touch "+" once. See Figure 1, the control circuit board module 105 gives information to the electric thermostatic valve core 2, the motor 22 contracts the output shaft 221 to drive the valve stem 23 to move right, the water outlet section of the water outlet end of the second water inlet channel 13 (for hot water) becomes larger, the water outlet section of the valve core water outlet 213 (for cold water) becomes smaller, the hot water flow increases, the cold water flow decreases, and the temperature rises. On the contrary, the motor 22 contracts the output shaft 221 to drive the valve stem 23 to move left, the water outlet section of the water outlet end of the second water inlet channel 13 (for hot water) becomes smaller, the water outlet section of the valve core water outlet 213 (for cold water) becomes larger, the hot water flow decreases, the cold water flow increases, and the temperature rises. When the mixed water flows through the temperature sensor 3 when adjusting the temperature, the temperature sensor 3 detects the current water temperature in real time. The control circuit board module 105 compares the detected water temperature value with the set water temperature value and gives information to the motor 22 to make a telescopic action, and adjusts the water temperature and constant temperature in real time.

[0093] 2) Turn off the water outlet: touch the corresponding sensing mark on the glass panel again, and the system sends a pulse signal to the solenoid valve 7. At this time, the right-end coil module in the valve head 713 of the solenoid valve 7 is energized to generate a magnetic field. The magnetic force of the magnetic field is greater than the magnetic force of the first magnet 185. Under the action of the second spring 714, the magnetic guide column 715 drives the fifth sealing ring 716 to move to the right, closing and blocking the pressure relief hole 701 in the center of the second valve seat 712. At this time, water flows into the water cavity at the left end of the diaphragm 82 from the water inlet hole of the diaphragm 82. Since the pressure relief hole 701 is in a closed state, the water cavity at the left end of the diaphragm 82 is equipped with a fourth spring 83. Under the action of the fourth spring 83, the pressure in the water cavity at the left end of the diaphragm 82 is greater than the pressure in the water cavity at the right end. The diaphragm 82 moves to the right to close the water outlet of the second valve body 711.

[0094] Manual operation:

[0095] 1) Manual opening: Figure 8 As shown, the corresponding knob 731 is rotated clockwise, the screw 732 moves rightward, the screw 732 drives the second magnet 722 to move rightward, the second magnet 722 moves rightward until it contacts the first magnet 721, and then the magnetic guide column 715 moves leftward and drives the fifth sealing ring 716 to move leftward. Under the magnetic force of the first magnet 721 and the second magnet 722, the magnetic guide column 715 and the fifth sealing ring 716 are kept at the leftmost end of the valve head 713 of the electromagnetic valve part 71. At this time, the pressure relief hole 701 in the center of the second valve seat 712 is opened, and the water cavity pressure at the left end of the diaphragm 82 flows from the water inlet holes on both sides of the second valve seat 712 to the pressure relief hole 701 for pressure relief. The water flow drives the diaphragm 82 to move leftward, the water outlet inside the second valve body 711 is opened, and the water flows out from the water outlet of the second valve body 711. The water flow is always in the open state.

[0096] 2) Manual shutdown: Figure 8The corresponding knob 731 is rotated counterclockwise, and the screw 732 moves leftward, and the screw 732 drives the second magnet 722 and the first magnet 721 to move leftward. When the second magnet 722 moves up to a certain distance, due to the weakening of the magnetic field, the magnetic guide column 715 and the fifth sealing ring 716 move rightward to close the pressure relief hole 701 under the action of the second spring 714. At this time, the water flows from the water inlet of the diaphragm 82 into the water cavity at the left end of the diaphragm 82. Since the pressure relief hole 701 is in a closed state, the water cavity at the left end of the diaphragm 82 is equipped with a fourth spring 83. Under the action of the fourth spring 83, the pressure in the water cavity at the left end of the diaphragm 82 is greater than the pressure in the water cavity at the right end, and the diaphragm 82 moves down to close the water outlet of the valve body. At the same time, the first magnet 721 stops moving when it moves to the left position in the fixed seat 724, and the second magnet 722 continues to move to the leftmost end. Since the magnetic force between the first magnet 721 and the second magnet 722 is reduced after the first magnet 721 is separated from the second magnet 722, the first magnet 721 is reset to the original right state under the action of the third spring 734. At this point, the water outlet is shut off.

[0097] When the cold water in the mixed water outlet channel 14 needs to be drained before taking a shower, the corresponding switch on the glass panel 52 is touched, and the control circuit board module 105 sends information to the electric thermostatic valve core 2. The motor 22 contracts the output shaft 221 to drive the valve stem 23 to move right. At this time, the water outlet end of the second water inlet channel 13 (for hot water) is opened, and the valve core outlet 213 (for cold water) is closed. The water flows through the temperature sensor 3 and the hydroelectric generator core 9 to the solenoid valve 7. At the same time, the control circuit board module 105 sends a pulse signal to the solenoid valve 7. At this time, the coil module in the valve head 713 of the solenoid valve part 71 is energized to generate a magnetic field, and the magnetic force of the magnetic field is greater than that of the second spring 71. 4 elastic force, adsorbs the magnetic guide post 715 to move upward, and drives the fifth sealing ring 716 to move upward and compress the second spring 714, the guide post moves to the upper end of the valve head 713, the pulse information stops, the magnetic field of the valve head 713 disappears, and the magnetic guide post 715 is adsorbed by the first magnet 721 to prevent it from moving downward. At this time, the pressure relief hole 701 in the center of the second valve seat 712 opens, and the water cavity pressure on the upper part of the diaphragm 82 flows from the water inlet holes on both sides of the second valve seat 712 to the pressure relief hole 701 in the middle of the second valve seat 712 to relieve pressure. The water flow pushes the diaphragm 82 to move upward, the water outlet inside the second valve body 711 opens, and the water flows out from the water outlet of the second valve body 711. When the temperature sensor 3 senses that the water temperature changes and rises, the cold water in the mixed water outlet channel 14 has been drained, and the control circuit board module 105 automatically sends a pulse signal to close the solenoid valve 7 to complete the pre-drain cold water operation.
