Description

Technical Field

[0002] With the development of bathroom equipment, induction faucets are becoming more and more popular. Most induction faucets use solenoid valves to control the water circuit. The pilot solenoid valve only needs to be powered on to give a signal when opening or closing, which is extremely energy-saving. Therefore, most of the solenoid valves used in faucet control valves are pilot solenoid valves. However, the pilot solenoid valve has the following inevitable defects: First, after the pilot solenoid valve is opened, if the system is powered off or out of power, the solenoid valve will remain in the open state and cannot be closed, resulting in a serious waste of resources; second, the solenoid valve needs to be powered on to achieve its control performance. If the system is powered off, the solenoid valve will not be able to be used, and the final result is Causing the faucet to be unusable; as in the invention patent with publication number CN117404516A, it discloses a pilot solenoid valve, which comprises: a valve body with a valve chamber and an insertion opening, the valve chamber is connected to an inlet opening and an outlet opening, the insertion opening is connected to the valve chamber, a pilot valve core capable of moving relative to the valve body, a main valve core capable of moving relative to a valve seat in the valve chamber or away from the valve seat, and a sleeve inserted into the insertion opening, the main valve core slides along the inner circumferential surface of the sleeve, although it improves the sealing performance of the pilot solenoid valve, it still cannot overcome the above-mentioned defects.

[0025] like Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, in one of the technical solutions, the diaphragm assembly includes: The water guide column 13 is connected to the pressure relief hole 14 and the water outlet pipe 10.

The edge of the diaphragm 12 is sealed with the inner wall of the valve seat 1 in the vertical direction. The diaphragm 12 is connected to the top of the valve seat 1 through the second spring 11, that is, the upper part of the diaphragm 12 is subjected to the force given by the second spring 11, and the lower part of the diaphragm 12 is subjected to the force given by the water. When the magnetic guide column moves upward to away from the pressure relief hole 14, the pressure relief hole 14 opens, and the water above the diaphragm 12 flows from the water inlet hole 15 of the valve seat to the pressure relief hole 14 to relieve pressure. After the water enters the water inlet pipe 2, the force given by the water to the diaphragm 12 is greater than the force given by the second spring 11 to the diaphragm 12, which pushes the diaphragm 12 to move upward, and the water flows out from the water outlet pipe 10.

[0029] like Figures 1 to 7 As shown, in one of the technical solutions, the pressing component includes: An adjusting sleeve 6, which is sealed and inserted into a slot on the bottom plate 7, and a fixing tooth 600 is provided inside the adjusting sleeve 6; A pressing rod 5, which is sealed and inserted into the adjusting sleeve 6 from the top of the adjusting sleeve 6, and the first flower teeth 51 are arranged on the outer side of the pressing rod 5; A guide sleeve 64 is inserted into the pressing rod 5 from the bottom of the adjusting sleeve 6, and a second flower tooth 640 adapted to the first flower tooth 51 is provided on the outer side of the guide sleeve 64, and the second flower tooth 640 is adapted to the fixed tooth 600, and a connecting rod 61 is provided at the bottom of the guide sleeve 64, and the bottom of the connecting rod 61 is connected to the second magnet 62; A return spring, comprising a fourth spring 65 sleeved on the extension block 71 and extending into the guide sleeve 64 and a fifth spring 63 disposed in the pressing rod 5 and connected to the guide sleeve 64; Among them, pressing the pressing rod 5 drives the connecting rod 61 to move downward, so that the first magnet 72 and the second magnet 62 are adsorbed, and continuing to press the pressing rod 5 drives the guide sleeve 64 to axially rotate and disengage from the position of the adjustment sleeve 6, and the fourth spring 65 and the fifth spring 63 drive the connecting rod 61 to move upward, so that the first magnet 72 and the second magnet 62 are separated.

[0030] In the above technical solution, the pressing assembly is arranged on the fixing seat, and the pressing assembly includes an adjusting sleeve 6, a pressing rod 5, a guide sleeve 64 and a reset spring, wherein the adjusting sleeve 6 is sealed and inserted into the slot on the bottom plate 7, and a fixing tooth 600 is arranged in the adjusting sleeve 6, and the pressing rod 5 is sealed and inserted into the adjusting sleeve 6 from the top of the adjusting sleeve 6, and the guide sleeve 64 is inserted into the pressing rod 5 from the bottom of the adjusting sleeve 6, and the outer side of the pressing rod 5 and the outer side of the guide sleeve 64 are respectively provided with an appropriate The guide sleeve 64 is provided with a first flower tooth 51 and a second flower tooth 640, that is, the guide sleeve 64 has an inner core inserted into the pressing rod 5, and the first flower tooth 51 and the second flower tooth 640 are arranged in the vertical direction to realize the downward pressing of the pressing rod 5, and the second flower tooth 640 is adapted with the fixed tooth 600 at the same time, and the guide sleeve 64 is positioned with the adjusting sleeve 6 to realize that the pressing rod 5 is fixed to the pressing state, and the pressing rod 5 continues to be pressed, and the pressing rod 5 drives the guide sleeve 64 to rotate axially to disengage the positioning of the adjusting sleeve 6. A connecting rod 61 is provided at the bottom of the guide sleeve 64, and a second magnet 62 is provided at the bottom of the connecting rod 61. When the pressing rod 5 is in a normal state, part of the connecting rod 61 is located in the first cavity, and the second magnet 62 is located in the second cavity. The pressing rod 5 is pressed, and the pressing rod 5 drives the guide sleeve 64 to move downward, thereby driving the connecting rod 61 to move downward, and finally driving the second magnet 62 to move downward, passing through the third spring 73 and adsorbing with the first magnet 72, thereby increasing the magnetic force on the magnetic guide column, and the magnetic guide column moves upward to open the pressure relief hole. At the same time, the second tooth on the guide sleeve is fixed by the fixed tooth, and the water path is connected; the pressing rod 5 is pressed again to drive the guide sleeve 64 to rotate axially to disengage from the position of the adjusting sleeve 6. Under the action of the reset spring provided in the guide sleeve 64 and the pressing rod 5, the pressing rod 5 returns to the starting position, the second magnet 62 moves away from the first magnet 72, and the magnetic guide column abuts against the pressure relief hole 14, and the water path is blocked.

[0031] like Figure 3 In one of the technical solutions, a recessed portion is provided on the top of the valve seat 1, and the pressure relief hole 14 and a pair of valve seat water inlet holes 15 are both arranged in the recessed portion. Water flows through the valve seat water inlet holes 15 into the recessed portion and flows toward the pressure relief holes 14, thereby relieving pressure. At the same time, a positioning hole 17 is provided on the top of the valve seat 1 to realize the positioning and installation of the valve head 3.

[0032] In one of the technical solutions, a bolt sleeve 8 is provided on the outside of the valve head 3, and bolt holes corresponding to the positions of the bolt sleeve 8 are provided on the bottom plate 7 and the top of the valve seat 1. The bolt holes 41 on the top of the valve seat are arranged on the four corners of the valve seat. The solenoid valve part is connected to the mechanical valve part by bolts 4, and the connection point between the mechanical valve part and the solenoid valve part is outside the control valve, thereby reducing the sealing requirements.

[0033] like Figure 2 As shown, in one of the technical solutions, a filter screen 21 is provided at the water inlet of the water inlet pipe 2 to prevent the water inlet pipe 2 from being blocked.

[0034] In one of the technical solutions, the operation process of the mechatronic faucet control valve is as follows: 1. Opening process of the solenoid valve: the faucet sensing part 102 gives a pulse signal to energize the first magnetic induction coil to generate a magnetic field (taking the infrared sensing sensor as an example, when the hand is within the recognition range of the infrared sensing sensor, the faucet sensing part gives a pulse signal). The magnetic force of the generated magnetic field on the magnetic guide column is greater than the pulling force of the first spring 32 on the magnetic guide column. The magnetic guide column moves upward and compresses the first spring 32. When the magnetic guide column moves to the upper part of the valve head 3, the pulse signal stops, and the magnetic field generated by the first magnetic induction coil disappears, but the first magnet 72 adsorbs the magnetic guide column to prevent the magnetic guide column from moving downward. At this time, the pressure relief hole 14 on the top of the valve seat 1 is opened, and water enters the upper part of the diaphragm 12 from the diaphragm water inlet hole. The water above the diaphragm 12 flows from the valve seat water inlet hole 15 to the pressure relief hole 14 for pressure relief. The water flows through the filter screen 21 and enters the water inlet pipe 2, pushing the diaphragm 12 to move upward. The valve seat 1 is opened, and the water flows out from the water outlet pipe 10. The water flow is always in an open state. 2. Closing process of the electromagnetic valve: the faucet sensing part 102 feeds back a pulse signal so that the second magnetic induction coil is energized to generate a magnetic field (taking the infrared sensing sensor as an example, after the hand leaves the recognition range of the infrared sensing sensor, the faucet sensing part feeds back a different pulse signal). The magnetic force of the generated magnetic field on the magnetic guide column is greater than the magnetic force of the first magnet 72 on the magnetic guide column. The magnetic guide column moves downward under the action of the first spring 32 to block the pressure relief hole 14. At this time, water flows into the top of the diaphragm 12 from the water inlet hole of the diaphragm 12. Since the pressure relief hole 14 is in a closed state, a second spring 11 is provided above the diaphragm 12. The total force of the second spring 11 and the water pressure above the diaphragm 12 is greater than the force of the water pressure below the diaphragm 12. The diaphragm 12 moves downward to close the valve seat 1, and the water flow is closed; 3. Manual opening process of mechanical valve: Figure 6As shown, pressing the pressing rod 5 drives the guide sleeve 64 to move downward, compressing the fourth spring 65 and the fifth spring 63, and the connecting rod 61 at the bottom of the guide sleeve 64 drives the second magnet 62 to pass downward through the fourth spring 65 and adsorb and approach the first magnet 72, thereby increasing the overall magnetic force and adsorbing the magnetic guide column to move upward. The second flower teeth 640 on the guide sleeve 64 cooperate with the fixed teeth 600 on the adjusting sleeve 6 to play a blocking role, so that the magnetic guide column is maintained at the upper part of the valve head 3. At this time, the pressure relief hole 14 on the top of the valve seat 1 is opened, and water enters the upper part of the diaphragm 12 from the water inlet hole of the diaphragm 12, and the water above the diaphragm 12 flows into the pressure relief hole 14 from the water inlet hole 15 of the valve seat to relieve pressure. The water flows into the water inlet pipe 2 after passing through the filter screen 21, pushing the diaphragm 12 to move upward, the valve seat 1 is opened, and the water flows out from the water outlet pipe 10, and the water flow is always in an open state; 4. Manual closing process of mechanical valve: Figure 7 As shown, the pressing rod 5 is pressed again, and the first tooth 51 on the pressing rod 5 drives the guide sleeve 64 to rotate a certain angle, so that the guide sleeve 64 is separated from the blocking position of the adjusting sleeve 6. The guide sleeve 64 moves upward under the action of the fourth spring 65 and the fifth spring 63, driving the second magnet 62 at the bottom of the connecting rod 61 to move upward. When the second magnet 62 is away from the first magnet 72, the overall magnetic force decreases, and the magnetic guide column is reset to abut against the pressure relief hole 14 under the action of the first spring 32, blocking the pressure relief hole 14. At this time, water flows into the upper part of the diaphragm 12 from the water inlet hole of the diaphragm 12. Since the pressure relief hole 14 is in a closed state, a second spring 11 is provided above the diaphragm 12. The total force of the second spring 11 and the water pressure above the diaphragm 12 is greater than the force of the water pressure below the diaphragm 12. The diaphragm 12 moves downward to close the valve seat 1, and the water flow is closed. 5. Emergency operation process: When the solenoid valve is used to open the faucet and the power is suddenly cut off, the magnetic guide column is adsorbed by the first magnet 72 and cannot move downward to close the valve seat 1. At this time, the pressing rod 5 is pressed to drive the guide sleeve 64 downward, compressing the fourth spring 65 and the fifth spring 63. The connecting rod 61 at the bottom of the guide sleeve 64 drives the second magnet 62 to move downward and adsorb close to the first magnet 72, adsorbing the magnetic guide column to move upward, and the second flower teeth 640 on the guide sleeve 64 cooperate with the fixed teeth 600 on the adjustment sleeve 6 to play a role in positioning, so that the magnetic guide column remains At the upper part of the valve head 3, the pressing rod 5 is pressed again, and the first tooth 51 on the pressing rod 5 drives the guide sleeve 64 to rotate a certain angle, so that the guide sleeve 64 is disengaged from the blocking position of the adjusting sleeve 6, and the guide sleeve 64 moves upward under the action of the fourth spring 65 and the fifth spring 63, driving the second magnet 62 at the bottom of the connecting rod 61 to move upward. When the second magnet 62 moves away from the first magnet 72, the overall magnetic force decreases, and the magnetic guide column is reset to abut against the pressure relief hole 14 under the action of the first spring 32, thereby blocking the pressure relief hole 14 and closing the water flow.
