Description

Technical Field

[0001] The present invention relates to the field of faucet control valves. More specifically, the present invention relates to an electromechanical integrated faucet control valve and a faucet. Background Art

[0002] With the development of sanitary equipment, induction faucets are becoming more and more popular. Most induction faucets use solenoid valves to control the water path. The pilot-operated solenoid valve only needs to be energized to give a signal during opening or closing operations, which is extremely power-saving. Therefore, most of the solenoid valves used in faucet control valves are pilot-operated solenoid valves. However, the pilot-operated solenoid valve has the following inevitable defects: First, if the system power fails or the power is cut off after the pilot-operated solenoid valve is opened, the solenoid valve will always remain in the open state and cannot be closed, resulting in serious waste of resources; Second, the solenoid valve needs to be powered to achieve its control performance. If the power is cut off in the system, the solenoid valve will not be able to be used, and ultimately the faucet will not be able to be used. For example, in the invention patent with publication number CN117404516A, it discloses a pilot-operated solenoid valve, and the pilot-operated solenoid valve has: a valve body having a valve chamber and an insertion opening, the valve chamber communicating with an inlet opening and an outlet opening, the insertion opening being connected to the valve chamber, a pilot spool capable of relatively moving with respect to the valve body, a main spool capable of moving relative to a valve seat in the valve chamber or away from it, and a bushing inserted into the insertion opening. The main spool slides along the inner peripheral surface of the bushing. Although it improves the sealing performance of the pilot-operated solenoid valve, it still cannot overcome the above defects.

[0003] Based on the above inevitable defects, a mechanical spool needs to be installed in parallel on the water path of the induction faucet for emergency use, which can avoid the above defects to a certain extent. However, setting an emergency mechanical spool makes the water path structure more complex, with high costs, a large valve body volume, an increase in sealing points, and more stringent sealing requirements. Even if an emergency mechanical spool is set, its operation is not convenient. Therefore, there is an urgent need for an electromechanical integrated faucet control valve that can achieve both electric control and manual control of the faucet and avoid the above defects without changing the water path structure. Summary of the Invention

[0041] The following further describes the present invention in detail with reference to the drawings, so that those skilled in the art can implement it according to the description in the specification.

[0042] It should be understood that the terms such as "having", "comprising" and "including" used herein do not exclude the presence or addition of one or more other elements or their combinations.

[0043] As Figures 1-7 shown, the present invention provides an electro-mechanical integrated faucet control valve, including:

[0044] An electromagnetic valve part, which includes a valve body, a valve seat 1 and a valve head 3 that are hermetically arranged in sequence from bottom to top. The valve body includes a water inlet pipeline 2 and a water outlet pipeline 10 that are separately arranged; the valve seat 1 is hermetically connected to the water inlet pipeline 2 and the water outlet pipeline 10. A diaphragm assembly for switching the valve seat 1 is arranged in the valve seat 1, and a pressure relief hole 14 communicating with the water outlet pipeline 10 is arranged at the top of the valve seat 1; a magnetic guide column that can move in the vertical direction is arranged in the valve head 3 through a first spring 32. First magnetic induction coils and second magnetic induction coils are respectively arranged at the top and bottom of the valve head 3. Both the first magnetic induction coil and the second magnetic induction coil are connected to a power supply. When the first magnetic induction coil is energized, the magnetic guide column moves away from the pressure relief hole 14. When the second magnetic induction coil is energized, the magnetic guide column abuts against the pressure relief hole 14;

[0045] A mechanical valve part, which includes a pressing component and a fixed seat that communicate up and down. The fixed seat is hermetically arranged on the top of the electromagnetic valve assembly. A first magnet 72 is arranged at the bottom of the fixed seat, and the first magnet 72 is located above the magnetic guide column. A second magnet 62 is arranged at the bottom of the pressing component. When the pressing component is pressed or lifted, the first magnet 72 and the second magnet 62 are attracted or separated, so that the magnetic guide column moves away from or abuts against the pressure relief hole 14;

[0046] Wherein, when the magnetic guide column moves away from or abuts against the pressure relief hole 14, the diaphragm 12 assembly opens or closes the valve seat 1.

[0047] In the above technical solution, the mechatronic faucet control valve includes an electromagnetic valve part and the mechanical valve part. The electromagnetic valve part is used to electrically control the valve seat 1 to open and close the water passage, and the mechanical valve part is used to manually control the valve seat 1 to open and close the water passage. The electric control operation and manual operation are realized simultaneously on the integrated control valve, which improves the functionality of the faucet control valve and solves the problem that the faucet cannot be opened or closed after the solenoid valve is powered off.

[0048] In the above technical solution, the electromagnetic valve part in the mechatronic faucet control valve includes a valve body, a valve seat 1 and a valve head 3. The valve body includes an inlet water pipe 2 and an outlet water pipe 10 arranged at intervals. The inlet water pipe 2 has at least one water inlet, and the outlet water pipe 10 has at least one water outlet. The water inlet is connected to the water inlet pipe of the faucet to connect to the water source, and the water outlet is communicated with the water outlet of the faucet to realize the water outlet of the faucet. The inlet water pipe 2 and the outlet water pipe 10 are connected through the valve seat 1, and the valve seat 1 controls whether the inlet water pipe 2 and the outlet water pipe 10 are communicated. The valve seat cavity has a water passage. When the valve seat 1 is opened (that is, the water passage in the valve seat cavity is opened), the inlet water pipe 2 and the outlet water pipe 10 form a water passage. When the valve seat 1 is closed (that is, the water passage in the valve seat cavity is closed), the water passage between the inlet water pipe 2 and the outlet water pipe 10 is blocked. The valve seat 1 controls the opening and closing of the valve seat 1 through a diaphragm assembly arranged in the valve seat 1. The diaphragm assembly controls the opening and closing of the valve seat 1 through the movement of a magnetic guide post. The magnetic guide post is arranged above the pressure relief hole 14 of the valve seat 1. The magnetic guide post is arranged in the valve seat 1 through a first spring 32. When the magnetic guide post moves upward away from the pressure relief hole 14, the diaphragm assembly opens the valve seat 1, and a water passage is formed between the inlet water pipe 2 and the outlet water pipe 10. When the magnetic guide post moves downward to abut against the pressure relief hole 14, the diaphragm assembly closes the valve seat 1, and the water passage between the inlet water pipe 2 and the outlet water pipe is blocked. Preferably, in order to increase the sealing performance between the magnetic guide post and the pressure relief hole 14, a sealing ring for sealing the pressure relief hole 14 is provided at the bottom of the magnetic guide post. The structure for controlling the movement of the magnetic guide post in the electromagnetic valve part is the magnetic force generated by a first magnetic induction coil and a second magnetic induction coil arranged at the top and bottom of the valve head 3. When the first magnetic induction coil is energized, the magnetic guide post moves upward. When the second magnetic induction coil is energized, the magnetic guide post moves downward. The first magnetic induction coil and the second magnetic induction coil are connected to the power supply through a signal wire 9. A signal indicating that the first magnetic induction coil and the second magnetic induction coil are connected to the power supply is an induction signal, such as a temperature induction signal, such as Figure 8As shown, in a faucet structure, a temperature sensor is provided on the faucet body 100. The temperature sensor is connected to a micro control board inside the faucet body 100. The signal line 9 connected to the first magnetic induction coil and the second magnetic induction coil is also connected to the micro control board. The micro control board is connected to a power supply through a plug 103. After the temperature sensor feeds back a pulse signal for the first time, the first magnetic induction coil is energized. After the temperature sensor feeds back a pulse signal for the second time, the second magnetic induction coil is energized.

[0049] In the above technical solution, in the mechatronic faucet control valve, the mechanical valve part includes a pressing component and a fixed seat. A second magnet 62 and a first magnet 72 are respectively arranged on the pressing component and the fixed seat. The movement of the magnetic guide post is manually controlled through the magnetic attraction of the first magnet 72 and the second magnet 62, so as to control the diaphragm component to open and close the valve seat 1, and further control whether the water inlet pipe 2 is communicated with the water outlet pipe 10, fundamentally solving the problem that the solenoid valve cannot open and close the faucet in the case of system power failure or power outage.

[0050] In the above technical solution, the mechanical valve part is arranged above the solenoid valve part and is hermetically connected to the solenoid valve part. In the solenoid valve part, the diaphragm component opens and closes the valve seat 1 through the vertical movement of the magnetic guide post. The mechanical valve part controls the vertical movement of the magnetic guide post through the pressing component, and further makes the diaphragm component open and close the valve seat 1. The solenoid valve part and the mechanical valve part share the same water path, and the existing solenoid valve can be replaced without changing the original water path, with a wide range of application scenarios. Both the solenoid valve part and the mechanical valve part realize the opening and closing of the water path by controlling the vertical movement of the magnetic guide post, and they share the same switch sealing element, with a simple structure and reliable sealing.

[0051] As Figure 2 、 Figure 3 、 Figure 6 and Figure 7 shown, in one of the technical solutions, the diaphragm component includes:

[0052] A water guide column 13, which communicates the pressure relief hole 14 and the water outlet pipe 10,

[0053] A diaphragm 12, which is sleeved on the water guide column 13, and the edge of the diaphragm 12 is hermetically connected to the inner wall of the valve seat 1. A diaphragm water inlet hole is provided on the diaphragm 12, and the diaphragm water inlet hole is communicated with the water inlet pipe 2;

[0054] A second spring 11, which is sleeved on the water guide column 13 and connects the diaphragm 12 and the top of the valve seat 1;

[0055] Among them, a valve seat water inlet hole 15 is provided at the top of the valve seat 1, so that the water above the diaphragm 12 flows from the valve seat water inlet hole 15 to the pressure relief hole 14.

[0056] In the above technical solution, the diaphragm assembly includes a water guide column 13 connecting the pressure relief hole 14 and the water outlet pipeline 10, a diaphragm 12 sleeved at the bottom of the water guide column 13, and a second spring 11 connecting the diaphragm 12 and the top of the valve seat 1. 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 diaphragm 12 is subjected to the force given by the second spring 11 above, and the diaphragm 12 is subjected to the force given by water below. When the magnetic guide column moves upward away from the pressure relief hole 14, the pressure relief hole 14 opens, and the water above the diaphragm 12 flows from the valve seat water inlet hole 15 to the pressure relief hole 14 for pressure relief. After the water enters the water inlet pipeline 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, then the diaphragm 12 is pushed upward, and the water flows out from the water outlet pipeline 10.

[0057] As Figure 3 shown, in one of the technical solutions, there is a pair of valve seat water inlet holes. The pair of valve seat water inlet holes are located on both sides of the water guide column 13, namely the valve seat water inlet hole 15 and the valve seat water inlet hole 16. Water enters above the diaphragm 12 from the diaphragm water inlet hole, and the water above the diaphragm 12 flows from the pair of valve seat water inlet holes 15 to the pressure relief hole 14 for pressure relief, and the diaphragm 12 moves upward to open the valve seat 1.

[0058] As Figure 1 、 Figure 2 、 Figure 6 and Figure 7 shown, in one of the technical solutions, the fixing seat includes a bottom plate 7 and an extension block 71 provided on the bottom plate 7. A through cavity extending from the extension block 71 to the inside of the valve head 3 is provided on the extension block 71 and the fixing plate. The through cavity is opposite to the magnetic guide column. The through cavity includes a first cavity, a second cavity and a third cavity with gradually increasing diameters from top to bottom. Among them, the first magnet 72 is arranged at the bottom of the third cavity, and a third spring 73 is provided on the first magnet 72. The third spring 73 is located in the third cavity. The fixing seat includes a bottom plate 7 and an extension block 71 provided on the bottom plate 7. A through cavity extending from the extension block 71 to the inside of the valve head 3 is provided on the fixing seat. The through cavity sequentially includes a first cavity, a second cavity and a third cavity from top to bottom, where the diameters of the first cavity, the second cavity and the third cavity gradually increase. The third cavity is used to arrange the first magnet 72 and the third spring 73; on the one hand, the fixing seat is used to be hermetically connected to the control valve part, and on the other hand, it is used to be hermetically connected to the pressing assembly.

[0059] As Figures 1-7As shown, in one of the technical solutions, the pressing component includes:

[0060] An adjusting sleeve 6, which is hermetically inserted into a slot on the bottom plate 7. A fixed tooth 600 is provided inside the adjusting sleeve 6;

[0061] A pressing rod 5, which is hermetically inserted into the adjusting sleeve 6 from the top of the adjusting sleeve 6, and a first spline tooth 51 is provided on the outer side of the pressing rod 5;

[0062] A guide sleeve 64, which is inserted into the pressing rod 5 from the bottom of the adjusting sleeve 6. A second spline tooth 640 adapted to the first spline tooth 51 is provided on the outer side of the guide sleeve 64. The second spline tooth 640 is adapted to the fixed tooth 600. 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;

[0063] A return spring, which includes a fourth spring 65 sleeved on the extension block 71 and extending into the guide sleeve 64 and a fifth spring 63 provided in the pressing rod 5 and connected to the guide sleeve 64;

[0064] Wherein, 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. Continuing to press the pressing rod 5 drives the guide sleeve 64 to axially rotate away from the clamping position of the adjusting sleeve 6. 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 move away from each other.

[0065] In the above technical solution, the pressing assembly is arranged on the fixed seat. The pressing assembly includes an adjusting sleeve 6, a pressing rod 5, a guide sleeve 64 and a return spring. The adjusting sleeve 6 is hermetically inserted into a slot on the bottom plate 7. Fixed teeth 600 are provided inside the adjusting sleeve 6. The pressing rod 5 is hermetically inserted into the adjusting sleeve 6 from the top of the adjusting sleeve 6. The guide sleeve 64 is inserted into the pressing rod 5 from the bottom of the adjusting sleeve 6. A first spline tooth 51 and a second spline tooth 640 which are adapted to each other are respectively provided on the outer side of the pressing rod 5 and the outer side of the guide sleeve 64, that is, the guide sleeve 64 has a core inserted into the pressing rod 5, and the first spline tooth 51 and the second spline tooth 640 are arranged in the vertical direction to realize the downward pressing of the pressing rod 5. The second spline tooth 640 is simultaneously adapted to the fixed teeth 600, and the guide sleeve 64 is latched with the adjusting sleeve 6 to fix the pressing rod 5 to the pressed state. When the pressing rod 5 is further pressed, the pressing rod 5 drives the guide sleeve 64 to axially rotate and disengage from the latching position 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 the normal state, a part of the connecting rod 61 is located in the first cavity, and the second magnet 62 is located in the second cavity. When the pressing rod 5 is pressed, 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 to adsorb to the first magnet 72, increasing the magnetic force on the magnetic guide post. The magnetic guide post moves upward to open the pressure relief hole, and at the same time, the second spline tooth on the guide sleeve is fixed by the fixed teeth, and the waterway is unblocked. When the pressing rod 5 is pressed again, it drives the guide sleeve 64 to axially rotate and disengage from the latching position of the adjusting sleeve 6. Under the action of the return spring provided in the guide sleeve 64 and the pressing rod 5, the pressing rod 5 returns to the starting position state, the second magnet 62 moves away from the first magnet 72, and the magnetic guide post abuts against the pressure relief hole 14, and the waterway is blocked.

[0066] As Figure 3 described, in one of the technical solutions, a recessed portion is provided at 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 provided in the recessed portion. Water flows through the valve seat water inlet holes 15 into the recessed portion and flows to the pressure relief hole 14 to play a role in pressure relief. At the same time, a positioning hole 17 is provided at the top of the valve seat 1 to realize the positioning and installation of the valve head 3.

[0067] In one of the technical solutions, a bolt sleeve 8 is provided on the outer side of the valve head 3. Bolt holes corresponding to the position of the bolt sleeve 8 are provided at the top of the bottom plate 7 and the valve seat 1. The bolt holes 41 at the top of the valve seat are provided at the four corners of the valve seat. The solenoid valve part and the mechanical valve part are bolted 4. The connection point between the mechanical valve part and the solenoid valve part is outside the control valve, reducing the sealing requirements.

[0068] As Figure 2 shown, in one of the technical solutions, a filter screen 21 is provided at the water inlet of the water inlet pipeline 2 to prevent the water inlet pipeline 2 from being blocked.

[0069] In one of the technical solutions, the operation process of the mechatronic faucet control valve is as follows:

[0070] 1. Process of opening the solenoid valve part: The faucet induction part 102 gives a pulse signal to make the first magnetic induction coil energized to generate a magnetic field (taking the infrared induction sensor as an example, when the hand is within the recognition range of the infrared induction sensor, the faucet induction 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. However, 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 at the top of the valve seat 1 is opened, water enters above the diaphragm 12 from the diaphragm water inlet hole, and the water above the diaphragm 12 flows through the pressure relief hole 14 for pressure relief through the valve seat water inlet hole 15. The water flow passes through the filter screen 21 and then enters the water inlet pipeline 2, pushing the diaphragm 12 upward to open the valve seat 1, and the water flow flows out from the water outlet pipeline 10. The water flow is always in an open state;

[0071] 2. Process of closing the solenoid valve part: The faucet induction part 102 feeds back a pulse signal to make the second magnetic induction coil energized to generate a magnetic field (taking the infrared induction sensor as an example, after the hand leaves the recognition range of the infrared induction sensor, the faucet induction 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, the water flow enters above the diaphragm 12 from the diaphragm water inlet hole. Since the pressure relief hole 14 is in a closed state and a second spring 11 is provided above the diaphragm 12, the total acting force of the second spring 11 and the water pressure above the diaphragm 12 is greater than the acting 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;

[0072] 3. Process of manually opening the mechanical valve part: As 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. The connecting rod 61 at the bottom of the guide sleeve 64 drives the second magnet 62 to move downward through the fourth spring 65 and adsorb and approach the first magnet 72, increasing the overall magnetic force, adsorbing the magnetic guide post to move upward. The second spline teeth 640 on the guide sleeve 64 cooperate with the fixed teeth 600 on the adjusting sleeve 6 to play a positioning role, so that the magnetic guide post is maintained above the valve head 3. At this time, the pressure relief hole 14 at the top of the valve seat 1 is opened, and water enters above the diaphragm 12 from the water inlet hole of the diaphragm 12. The water above the diaphragm 12 flows into the pressure relief hole 14 from the valve seat water inlet hole 15 for pressure relief. After the water flow passes through the filter screen 21, it enters the water inlet pipeline 2, pushing the diaphragm 12 to move upward, the valve seat 1 is opened, and the water flow flows out from the water outlet pipeline 10. The water flow is always in an open state;

[0073] 4. Manual closing process of the mechanical valve part: As Figure 7 shown, pressing the pressing rod 5 again, the first spline teeth 51 on the pressing rod 5 drive the guide sleeve 64 to rotate a certain angle, so that the guide sleeve 64 disengages from the positioning 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 moves away from the first magnet 72, the overall magnetic force decreases, and the magnetic guide post returns 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, the water flow enters above the diaphragm 12 from the water inlet hole of the diaphragm 12. Since the pressure relief hole 14 is in a closed state, there is a second spring 11 above the diaphragm 12. The total acting force of the second spring 11 and the water pressure above the diaphragm 12 is greater than the acting 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;

[0074] 5. Emergency operation process: When the solenoid valve part is used to open the faucet and then suddenly loses power, at this time, the magnetic guide post is adsorbed by the first magnet 72 and cannot move downward to close the valve seat 1. At this time, press the pressing rod 5 to drive the guide sleeve 64 to move 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 to adsorb and approach the first magnet 72, adsorbing the magnetic guide post to move upward. The second spline teeth 640 on the guide sleeve 64 cooperate with the fixed teeth 600 on the adjusting sleeve 6 to play a card position role, so that the magnetic guide post is kept above the valve head 3. Press the pressing rod 5 again, and the first spline teeth 51 on the pressing rod 5 drive the guide sleeve 64 to rotate a certain angle, so that the guide sleeve 64 disengages from the card 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 moves away from the first magnet 72, the overall magnetic force decreases, and the magnetic guide post is reset to abut against the pressure relief hole 14 under the action of the first spring 32, blocking the pressure relief hole 14 and closing the water flow.
