Description

Technical Field

[0001] This utility model relates to the field of faucet valve core technology, specifically to a valve core and faucet that can adjust the water volume both manually and electrically. Background Technology

[0002] Chinese patent document CN120292283A discloses a dual-control mixing faucet valve core and faucet. The dual-control mixing faucet valve core includes the following structure: a fixing component with a water supply channel and a water outlet channel; and an adjusting component with an installation cavity in the fixing component. The adjusting component has a manual mixing chamber, an electric mixing chamber, and a sealing part. By moving the adjusting component in the installation cavity, the manual mixing chamber, the electric mixing chamber, or the sealing part can be selectively connected to the water supply channel, allowing the dual-control mixing faucet valve core to switch between manual control mode, electric control mode, and closed mode. When the dual-control mixing faucet valve core is in closed mode, neither the manual control mode nor the electric control mode can control the water flow, avoiding the leakage of the faucet when the solenoid valve is damaged, as is the case in the prior art.

[0003] Its drawback is that in electric control mode, when the electrically controlled mixing chamber and the water supply channel are connected, the system can only switch between "on" and "off," and cannot continuously and linearly adjust the water flow rate in electric control mode simply by moving the adjustment components. This means that users cannot flexibly adjust the water output according to actual needs in electric control mode, resulting in a limited user experience. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to propose a valve core and faucet that can adjust the water volume both manually and electrically, so as to solve the problems mentioned in the background section above.

[0005] This utility model is achieved through the following technical solution: A valve core for adjusting water flow both manually and electrically, comprising: A valve seat assembly, wherein the valve seat assembly is provided with a first water supply channel, a second water supply channel and a water outlet channel; The valve body, the valve seat assembly and the valve body are closed to form an installation chamber, and the installation chamber is provided with an adjustment component. By moving the adjustment component, the valve core with adjustable water volume can be switched between manual control mode and electric control mode. The regulating component is provided with a mixing chamber, and the lower end of the regulating component sequentially forms a first transition port, a second transition port and a mixing outlet; When in electronic control mode, the second transition port connects the first water supply channel, the second water supply channel and the mixing chamber, and the mixing outlet connects the water outlet channel. By moving the adjustment component, the connection area between the second transition port and the first water supply channel and the second water supply channel is changed, and / or the connection area between the mixing outlet and the water outlet channel is changed. When in manual control mode, the first transition port connects the first water supply channel, the second water supply channel and the mixing chamber, and the second transition port connects the water outlet channel. By moving the adjustment component, the connection area between the first transition port and the first water supply channel and the second water supply channel is changed, and / or the connection area between the second transition port and the water outlet channel is changed.

[0006] Furthermore, in electronic control mode, the connection area between the second transition port and the first water supply channel and the second water supply channel is changed by moving the adjustment component; in manual control mode, the connection area between the first transition port and the first water supply channel and the second water supply channel, and the connection area between the second transition port and the water outlet channel are changed by moving the adjustment component.

[0007] Furthermore, the regulating component passes through the mixing outlet along the central axis, the first transition port and the second transition port are in a ring structure, and the second transition port is disposed between the first transition port and the mixing outlet.

[0008] Furthermore, the central axial surface of the water outlet channel is arranged coplanarly with the central axial surface of the valve seat assembly, and the first water supply channel and the second water supply channel are arranged symmetrically along the central axial surface of the valve seat assembly. When the central axis surface of the adjusting component is arranged coplanarly with the central axis surface of the valve seat component, the second transition port has the same connection area with the first water supply channel and the second water supply channel, respectively, and the first transition port has the same connection area with the first water supply channel and the second water supply channel, respectively.

[0009] Furthermore, it also includes a guide seat and a control component. The guide seat is rotatably connected to the valve housing. The guide seat is provided with a guide groove. The upper support is provided with a guide portion that is embedded in the guide groove. One end of the control component passes through the valve housing. The control component is rotatably connected to the guide seat. The other end of the control component is embedded in the adjustment assembly. By swinging the control element, the adjustment component is moved horizontally within the mounting chamber; by rotating the control element, the communication area between the second transition port and the first water supply channel and the second water supply channel is changed, or the communication area between the first transition port and the first water supply channel and the second water supply channel is changed. When the swing angle of the control component is the first angle, the water output of the electronic control mode is the largest; as the swing angle of the control component increases, the water output of the electronic control mode gradually decreases; when the control component swings to the second angle, water begins to flow through the manual control mode; as the swing angle of the control component increases, the water output of the manual control mode gradually increases until the control component rotates to the third angle, at which point the water output of the manual control mode is the largest, with the first angle, second angle, and third angle increasing sequentially.

[0010] Furthermore, the first angle is 0°, and the third angle is less than 30°.

[0011] Furthermore, the regulating component includes a diaphragm, and a pressure relief chamber is provided at the rear end of the diaphragm.

The valve seat assembly includes a solenoid valve that is movable between a position that blocks and opens the pressure relief channel.

[0012] Furthermore, the adjustment assembly also includes an upper support, a middle support, and a spring. The diaphragm is disposed between the upper support and the middle support, and the spring is disposed between the upper support and the diaphragm. The upper end of the middle support is provided with a water-stopping surface.

[0013] Furthermore, it also includes a controller, a magnetic sensor is provided in the guide seat, the adjustment component includes a magnet, and the controller is communicatively connected to the magnetic sensor, the probe, and the solenoid valve; When the adjustable water volume valve core is in electronic control mode, the magnet is recognized by the magnetic sensor, and the magnetic sensor transmits a signal to the controller. The controller controls the probe and the solenoid valve to be in working state. The probe is used to recognize the hand-held signal and transmit it to the controller. The controller controls the solenoid valve to move between the position of opening and closing the pressure relief channel through the hand-held signal. When the adjustable water volume valve core is in manual control mode, the magnet cannot be recognized by the magnetic sensor, the controller controls the probe and the solenoid valve to be in a non-working state, and the controller controls the solenoid valve to close the pressure relief channel.

By moving the adjustment component, the connection area between the second transition port and the first water supply channel and the second water supply channel, and / or the connection area between the mixing outlet and the outlet channel can be changed.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is intended to aid in understanding this utility model, but does not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0029] Reference Figures 1 to 4 As shown, a valve core for adjusting water flow both manually and electrically includes: The valve seat assembly 1 includes a valve seat body 11 and a partition 12 that seals against the valve seat body 11. The valve seat assembly 1 is provided with a first water supply channel 1A, a second water supply channel 1B, a water outlet channel 1C, and a pressure relief channel 1D that pass through the valve seat body 11 and the partition 12. The first water supply channel 1A is used to supply cold water, and the second water supply channel 1B is used to supply hot water.

[0030] Valve seat assembly 1 also includes a solenoid valve 13, which is movable between opening and closing the pressure relief channel 1D, which is connected to the water outlet channel 1C.

[0031] The valve housing 2 and the valve seat assembly 1 are closed to form an installation chamber 21. An adjustment assembly 3 is provided in the installation chamber 21. By moving the adjustment assembly 3, the valve core with adjustable water volume can be switched between manual control mode and electric control mode.

[0032] The adjusting assembly 3 includes a diaphragm 31, an upper support 32, a middle support 33, a lower support 34, a spring 35, and a magnet 36. The diaphragm 31 is sandwiched between the upper support 32 and the middle support 33. The back end of the diaphragm 31 is provided with a pressure relief chamber 3A. The front end of the diaphragm 31 is provided with a first mixing chamber 3B and a second mixing chamber 3C arranged separately. The first mixing chamber 3B is provided with a filter screen 37, which is used to prevent impurities in the water from entering the pressure relief chamber 3A and the pressure relief channel 1D. The middle support 33 is provided with a water-stopping surface 331. When the diaphragm 31 abuts against the water-stopping surface 331, the first mixing chamber 3B and the second mixing chamber 3C are in a separated state. The lower end of the lower support 34 is provided with a first transition port 3D, a second transition port 3E, a mixing outlet 3F, a stop part 3G, and a pressure relief outlet 3H arranged in sequence. The second transition port 3E and the first transition port 3D are both connected to the first mixing chamber 3B, and the second mixing chamber 3C is connected to the mixing outlet 3F.

[0033] The guide seat 4 is disposed in the installation chamber 21 and is rotatably connected to the valve body 2. The guide seat 4 is provided with a guide rail groove 41, and first elastic columns 42 are provided on both sides of the guide rail groove 41. The upper support 32 is provided with a guide part 321 embedded in the guide rail groove 41. The guide part 321 is provided with a second spring pin 322. The tactile feedback of the first elastic column 42 and the second spring pin 322 abutting against each other provides feedback on the valve core of the dual-control faucet valve core to switch between manual control mode and electric control mode.

[0034] The control component 5 is rotatably connected to the guide seat 4 via a rotating shaft 43. The upper end of the control component extends out of the valve housing 2, and the lower end of the control component is embedded in the groove of the upper support 32. By swinging the control component 5, the adjustment component 3 is moved in the installation chamber 21, so that the valve core with adjustable water volume can switch between manual control mode, electric control mode or self-cleaning mode.

[0035] By rotating the control component 5, in electronic control mode, the communication area between the second transition port 3E and the first water supply channel 1A and the second water supply channel 1B is changed. In manual control mode, the communication area between the first transition port 3D and the first water supply channel 1A and the second water supply channel 1B is changed. The adjustable water volume valve core of this invention can adjust the outlet water temperature and flow rate in both manual and electronic control modes, improving the user experience.

[0036] The adjustable water volume valve core of this invention can switch between manual control mode, electric control mode and self-cleaning mode.

[0037] Reference Figure 4 and Figure 5 As shown, when the adjustable water volume valve core is in electronic control mode, the user manually signals the solenoid valve 13 to open the pressure relief channel 1D. Water flows through the first water supply channel 1A and the second water supply channel 1B into the second transition port 3E, and then through the second transition port 3E into the first mixing chamber 3B. Under water pressure, the diaphragm 31 disengages from the water stop surface 331, connecting the first mixing chamber 3B and the second mixing chamber 3C. Finally, the water flows out sequentially through the mixing outlet 3F and the outlet channel 1C. In this position, the second transition port 3E and the mixing outlet 3F are in a disconnected position.

[0038] Reference Figure 6 and Figure 7 As shown, when the adjustable water volume valve core is in manual control mode, the solenoid valve 13 closes the pressure relief channel 1D, and the water flows through the first water supply channel 1A and the second water supply channel 1B into the first transition port 3D, and then through the first transition port 3D into the first mixing chamber 3B. At this time, the second transition port 3E is connected to the outlet channel 1C, and the water flows out through the second transition port 3E and the outlet channel 1C in sequence.

[0039] Reference Figure 7 and Figure 8 As shown, when the adjustable water volume valve core is in self-cleaning mode, the stop part 3G blocks the pressure relief channel 1D. The communication area between the first transition port 3D and the first mixing chamber 3B is the largest, and the communication area between the second transition port 3E and the water outlet channel 1C is the largest, thereby maximizing the water output. This allows for maximum rinsing of the filter screen 37. During the rinsing process, because the stop part 3G blocks the pressure relief channel 1D, water pressure cannot be transmitted to the solenoid valve 13. This effectively prevents the solenoid valve 13's seals, diaphragms, coils, and other parts from being subjected to high-pressure loads for extended periods, thus avoiding deformation, leakage, or coil burnout. This significantly extends the service life of the solenoid valve 13 and reduces maintenance and replacement costs.

[0040] In manual control mode, the connection area between the first transition port 3D and the first water supply channel 1A and the second water supply channel 1B, and / or the connection area between the second transition port 3E and the outlet channel 1C, can be changed by moving the adjustment component 3. In electronic control mode, the connection area between the second transition port 3E and the first water supply channel 1A and the second water supply channel 1B, and / or the connection area between the mixing outlet 3F and the outlet channel 1C, can be changed by moving the adjustment component. This allows the water output to be changed by moving the adjustment component in both electronic and manual control modes.

[0041] The mixing outlet 3F is connected to the adjusting component 3 along the central axis. The first transition port 3D and the second transition port 3E form an annular structure, with the second transition port 3E located between the first transition port 3D and the mixing outlet 3F. (Refer to...) Figures 4 to 9 As shown, from right to left, the components are the first transition port 3D, the second transition port 3E, and the mixing outlet 3F. In electronic control mode, moving the adjusting component 3 to the right gradually reduces the connection area between the first transition port 3D and the first water supply channel 1A and the second water supply channel 1B. In manual control mode, moving the adjusting component 3 to the right gradually increases the connection area between the first transition port 3D and the first water supply channel 1A and the second water supply channel 1B, and also gradually increases the connection area between the second transition port 3E and the outlet channel 1C.

[0042] Reference Figures 4 to 8 , Figure 11 As shown, preferably, when the swing angle of the control component 5 is the first angle, the communication area between the second transition port 3E and the first water supply channel 1A and the second water supply channel 1B is maximized, resulting in the maximum water output in the electronically controlled mode. As the swing angle of the control component 5 increases, the water output in the electronically controlled mode gradually decreases. When the control component 5 swings to the second angle, water begins to flow through the manual control mode. As the swing angle of the control component 5 increases, the water output in the manual control mode gradually increases until the control component 5 rotates to the third angle, at which point the water output in the manual control mode is maximized. The maximum water output in the manual control mode indicates that the adjustable water volume valve core is in self-cleaning mode. The first angle, second angle, and third angle increase sequentially.

[0043] Users can smoothly transition between "maximum water output in electric control mode → gradually decreasing water output in electric control mode → starting manual control mode → gradually increasing water output in manual control mode → maximum water output in manual control mode (i.e., self-cleaning mode)" by simply swinging the control component 5 with one hand, without the need for additional buttons or switches.

[0044] Preferably, the first angle is 0° and the third angle is less than 30°. Specifically, the first angle is 0°, the second angle is 13°, and the third angle is 23°. When the first angle is precisely set to 0°, the control component 5 naturally resets to obtain the maximum water flow in the electronic control mode. When the control component 5 swings to its maximum of 23°, the maximum water flow in the manual control mode is obtained. The control component 5 does not protrude excessively from the faucet body, reducing space occupation.

[0045] Preferably, the first water supply channel 1A, the second water supply channel 1B, and the outlet channel 1C are arranged in the following manner at the partition 12: the central axis of the outlet channel 1C is coplanar with the central axis of the valve seat assembly 1, and the first water supply channel 1A and the second water supply channel 1B are symmetrically arranged along the central axis of the valve seat assembly 1. When the central axis of the adjusting component 3 is coplanar with the central axis of the valve seat assembly 1, the second transition port 3E has the same communication area with the first water supply channel 1A and the second water supply channel 1B, respectively, and the first transition port 3D has the same communication area with the first water supply channel 1A and the second water supply channel 1B, respectively.

[0046] With the above structure, when adjusting the water temperature, the user can intuitively perceive the opening and closing ratio of the first water supply channel 1A and the second water supply channel 1B by rotating the adjustment component 3 in either the forward or reverse direction, which facilitates temperature adjustment.

[0047] It also includes a controller, a magnetic sensor 44 is provided in the guide seat 4, the adjustment component 3 includes a magnet 36, and the controller is communicatively connected to the magnetic sensor 44, the probe, and the solenoid valve 13; the communication connection includes signal transmission via wired and wireless means.

[0048] When the adjustable water volume valve core is in electronic control mode, the magnet 36 is identified by the magnetic sensor 44, and the magnetic sensor 44 transmits a signal to the controller. The controller controls the probe and the solenoid valve 13 to be in working state. The probe is used to identify the hand-held signal and transmit it to the controller. The controller controls the solenoid valve 13 to move between the positions of opening and closing the pressure relief channel 1D through the hand-held signal. When the adjustable water volume valve core is in manual control mode and self-cleaning mode, the magnet 36 cannot be recognized by the magnetic sensor 44, the controller controls the probe and the solenoid valve 13 to be in a non-working state, and the controller controls the solenoid valve 13 to close the pressure relief channel 1D.

[0049] When a user is unaware that the faucet is a dual-control faucet that can be operated in both manual and electric modes, or when the probe is triggered in electric mode, causing the solenoid valve 13 to open the pressure relief channel 1D and start dispensing water, and then switches to manual mode, the controller will automatically control the solenoid valve 13 to close the pressure relief channel 1D. When the user finishes using the faucet and turns off the water, during the process of pushing the control piece 5 back to the first angle and switching to electric mode, because the controller controls the solenoid valve 13 to be in the correct position of closing the pressure relief channel 1D during manual control mode, the electric control mode is in the water-off state, and there is no need to turn off the water again through the probe.

[0050] With the above settings, users do not need to know that this is a dual-control faucet. Regardless of whether the water was previously manually or electrically controlled, as long as the control piece 5 is pushed back to the first angle, the controller has already closed the pressure relief channel 1D through the solenoid valve 13, and the faucet will immediately stop dispensing water. The learning cost is low, and there will be no misoperation on the first use.

[0051] In the above text, the probe can be an infrared sensing probe from existing technology.

[0052] This utility model, through the design of the pressure relief chamber 3A, avoids huge fluctuations in water pressure when the water is turned off due to the buffering effect of the spring 35, thereby protecting the pipeline, significantly reducing the "bang" noise, and extending the pipeline life. It is especially suitable for high-rise buildings or areas with unstable water pressure.

[0053] In this invention, due to the presence of the pressure relief chamber 3A and the pressure relief channel 1D, and the design of the pressure relief channel 1D being connected to the water outlet channel 1C, the diameter of the pressure relief channel 1D can be relatively small, and the water flow thrust is reduced accordingly. In this invention, the solenoid valve 13 with lower power can complete the closure of the pressure relief channel 1D, thereby completing the water shut-off action in the electric control mode. By selecting the solenoid valve 13 with lower power, it is beneficial to the miniaturization design of the valve core.

[0054] However, since the diameter of the pressure relief channel 1D is small, impurities in the water flow may enter the pressure relief channel 1D and block it. Therefore, in order to filter out impurities such as sand and gravel that may exist in the water, a filter screen 37 is provided in the first mixing chamber 3B to prevent impurities from entering the pressure relief chamber 3A and the pressure relief channel 1D, and to ensure that the flow area of ​​the pressure relief channel 1D is not affected by impurities in the water.

[0055] After long-term operation, impurities may accumulate on the surface of the filter screen 37. This utility model can automatically clean it by using the "self-cleaning mode": when the control piece 5 is switched to the gear corresponding to the self-cleaning mode, a large flow of water at high speed is generated in the first mixing chamber 3B to form strong turbulence, which directly backwashes the surface of the filter screen 37, quickly carrying away the attached particles, and then flowing through the second transition port 3E and the mixing outlet 3F to the water outlet channel 1C for discharge.

[0056] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

Thus, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.
