Description

Technical Field

[0001] This utility model relates to the field of faucet valve core technology, specifically to a pressure relief faucet valve core and faucet. 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 manual mode, the water flow is directly delivered to the outlet end through the water outlet channel inside the valve core, without passing through the pressure relief chamber. In electric mode, the water flow passes through the pressure relief chamber and is then discharged through the subsequent channel. Therefore, due to the inherent differences in the resistance characteristics and flow cross-sectional area of ​​different flow channels, the water flow rate and velocity are inconsistent between manual and electric modes under the same water pressure, affecting the consistency of the 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 pressure relief faucet valve core and faucet to solve the problems mentioned in the background section above.

[0005] This utility model is achieved through the following technical solution: A pressure-relief faucet valve core includes: 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 and the valve seat assembly are closed to form an installation chamber. An adjustment component is provided in the installation chamber. By moving the adjustment component, the faucet valve core can be switched between manual and electric control modes. The regulating component includes a diaphragm, and a pressure relief chamber is provided at the rear end of the diaphragm. The regulating component includes a first pressure relief channel communicating with the pressure relief chamber, and the front end of the channel is divided into a first mixing chamber and a second mixing chamber by the diaphragm. The lower end of the adjustment component forms a first transition port and a second transition port in sequence. Both the first transition port and the second transition port are connected to the first mixing chamber, and the second mixing chamber is connected to the water outlet channel. The valve seat assembly is provided with a second pressure relief channel, which is connected to the water outlet channel. The valve seat assembly includes a solenoid valve, which is used to isolate or open the second pressure relief channel. When the faucet valve core is in the electronic control mode, the second transition port is connected to the first water supply channel and the second water supply channel, the second mixing chamber is connected to the water outlet channel, and the first pressure relief channel is connected to the second pressure relief channel. When the faucet valve core is in manual control mode, the first transition port is connected to the first water supply channel and the second water supply channel, and the first pressure relief channel is connected to the water outlet channel.

[0006] Furthermore, the valve seat assembly includes a partition plate with a transition groove. When the faucet valve core is in manual control mode, the transition groove connects the second mixing chamber with the first pressure relief channel.

[0007] 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. When the diaphragm abuts against the water-stopping surface, the first mixing chamber and the second mixing chamber are in a state of isolation.

[0008] Furthermore, it also includes a valve housing, a guide seat, and a control component. The guide seat is rotatably connected to the valve housing and has a guide groove. The upper support has a guide portion that is embedded in the guide groove. One end of the control component passes through the valve housing and 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 swings 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.

[0009] 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 faucet valve core is in electronic control mode, the magnet is recognized by the magnetic sensor, which transmits the 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 disconnect or open the second pressure relief channel through the hand-held signal. When the faucet valve core is in manual control mode, the magnet cannot be recognized by the magnetic sensor, the controller controls the solenoid valve to be in a non-working state, and the controller controls the solenoid valve to close the second pressure relief channel.

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

[0011] 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.

[0012] Furthermore, a feedback structure is provided between the adjustment component and the guide seat. The feedback structure uses tactile feedback to indicate to the user that the faucet valve core has been switched between manual control mode and electric control mode.

[0013] Furthermore, the feedback structure includes at least two first elastic pillars and two second elastic pillars. The two first elastic pillars are respectively disposed on the inner walls of the guide rail grooves on both sides of the guide seat, and the two second elastic pillars are respectively disposed on both sides of the upper support.

[0014] On the other hand, this utility model provides a faucet, including a pressure relief faucet valve core as described in any of the preceding claims.

[0015] The beneficial effects of this utility model are as follows: A pressure-relief faucet valve core, when the faucet valve core is in electronic control mode, the second transition port connects to the first and second water supply channels, the outlet channel of the second mixing chamber connects to the outlet channel, and the first pressure relief channel connects to the second pressure relief channel; when the faucet valve core is in manual control mode, the first transition port connects to the first and second water supply channels, and the first pressure relief channel connects to the outlet channel. By optimizing the channel connection structure of the faucet valve core, water flow in both manual and electronic control modes can flow through the pressure relief chamber, eliminating the flow path differences caused by different modes in the prior art. Under the same water pressure conditions, the deviation of water flow rate and velocity between manual and electronic control modes is significantly reduced. When switching between different modes, the user's water experience (such as water flow intensity and flow velocity) remains as consistent as possible, avoiding discomfort caused by sudden changes in flow rate.

[0027] 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.

[0028] Reference Figures 1 to 10 As shown, a pressure-relief faucet valve core 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 has a first water supply channel 1A, a second water supply channel 1B, a water outlet channel 1C, and a second pressure relief channel 1D that pass through the valve seat body 11 and the partition 12. The second pressure relief channel 1D communicates with the water outlet channel 1C. 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.

[0029] The valve seat assembly 1 also includes a solenoid valve 13, which is used to disconnect or open the second pressure relief passage 1D.

[0030] The valve housing 2, the valve seat assembly 1 and the valve housing 2 are closed to form an installation chamber 21, the installation chamber 21 is provided with an adjustment assembly 3, by moving the adjustment assembly 3, the valve core with adjustable water volume can be switched between manual control mode and electric control mode; Adjustment component 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 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 face of the lower support 34 is provided with a first transition port 3D and a second transition port 3E. The second transition port 3E and the first transition port 3D are both connected to the first mixing chamber 3B. The second mixing chamber 3C penetrates the lower end face of the lower support 34. The adjusting assembly 3 also includes a first pressure relief channel 3F connected to the pressure relief chamber 3A. The first pressure relief channel 3F penetrates the lower end face of the lower support 34. The stop portion 3G of the lower support 34 separates the second mixing chamber 3C and the first pressure relief channel 3F. The first transition port 3D, the second transition port 3E, the second mixing chamber 3C, the stop portion 3G, and the first pressure relief channel 3F are arranged sequentially from left to right or from right to left.

[0031] Guide seat 4 is disposed in the mounting chamber 21 and is rotatably connected to the valve body 2. The guide seat 4 is provided with a guide rail groove 41.

[0032] A feedback structure is provided between the adjustment component 3 and the guide seat 4. This feedback structure uses tactile feedback to indicate to the user that the faucet valve core has been switched between manual and electric control modes. This tactile feedback intuitively informs the user that the mode switch has been completed, eliminating the need for visual observation and improving the comfort and satisfaction of using the product.

[0033] The feedback structure includes at least two first elastic pillars 42 and two second elastic pillars 322. The first elastic pillars 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 second elastic pillars 322. Through the tactile sensation of the first elastic pillars 42 and the second elastic pillars 322 abutting against each other and deforming, the feedback valve core switches between manual control mode and electric control mode.

[0034] As another embodiment (not shown in the figure), the feedback structure can be: the spring pins and recessed structures respectively set on the adjustment component 3 and the guide seat 4 cooperate to provide feedback through the extension and retraction of the spring pins and recessed structures.

[0035] 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.

[0036] By rotating the control component 5, 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 is changed. 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 is changed. This allows for adjustment of the water temperature and flow rate in both manual and electronic control modes, improving the user experience.

[0037] Reference Figures 3 to 5 As shown, when the faucet valve core is in the electronic control mode, by moving the adjustment component 3, the second transition port 3E is connected to the first water supply channel 1A and the second water supply channel 1B, the second mixing chamber 3C is connected to the water outlet channel 1C, and the first pressure relief channel 3F is connected to the second pressure relief channel 1D.

[0038] In electronic control mode, when the user's hand signal is transmitted to the solenoid valve 13 via a probe, the solenoid valve opens the second pressure relief channel 1D according to the control signal. After the second pressure relief channel 1D opens, the pressure relief chamber 3A is depressurized, allowing the water flow to push the diaphragm 31 away from the stop surface 331. The water flows into the first water supply channel 1A and the second water supply channel 1B, then enters the first mixing chamber 3B through the second transition port 3E, and sequentially flows through the pressure relief chamber 3A, the first pressure relief channel 3F, and the second pressure relief channel 1D, finally flowing out through the outlet channel 1C. At the same time, due to the depressurization of the pressure relief chamber 3A, the water flow can push the diaphragm 31 away from the stop surface 331, thus the water flow enters the second mixing chamber 3C through the first mixing chamber 3B, and finally flows out through the outlet channel 1C.

[0039] Reference Figure 6 and Figure 7 As shown, when the faucet valve core is in manual control mode, by moving the adjustment component 3, the first transition port 3D is connected to the first water supply channel 1A and the second water supply channel 1B, and the first pressure relief channel 3F is connected to the water outlet channel 1C.

[0040] In manual control mode, water flows into the first water supply channel 1A and the second water supply channel 1B, then enters the first mixing chamber 3B through the first transition port 3D, and sequentially passes through the pressure relief chamber 3A and the first pressure relief channel 3F, finally flowing out through the outlet channel 1C. Simultaneously, due to the pressure relief in the pressure relief chamber 3A, the water flow can push the diaphragm 31 away from the stop surface 331, allowing the water to flow through the first mixing chamber 3B into the second mixing chamber 3C, and finally out through the outlet channel 1C.

[0041] Preferably, the partition 12 is provided with a transition groove 1E. When the faucet valve core is in the electronic control mode, the transition groove 1E is not connected to the second mixing chamber 3C. When the faucet valve core is in the manual control mode, the transition groove 1E connects the second mixing chamber 3C and the first pressure relief channel 3F, so that the water flows through the first pressure relief channel 3F into the transition groove 1E, bypasses the stop part 3G, and then enters the second mixing chamber 3C, and finally flows out through the outlet channel 1C. Thus, the arrangement of the transition groove 1E increases the flow area, thereby increasing the water flow rate in the manual control mode, so that the water in the pressure relief chamber 3A can be discharged in the manual control mode.

[0042] Another function of the pressure relief chamber 21 is that when the faucet is closed quickly, the high-speed water flow will impact the pipe due to inertia, generating a high-pressure water hammer effect. Through the buffering effect of the spring 35 inside the pressure relief chamber 21 and the water flow inside the pressure relief chamber 21, it can avoid huge fluctuations in water pressure when turning the water on or off as much as possible, thereby protecting the pipeline, significantly reducing the "bang" noise, and extending the life of the pipeline. It is especially suitable for high-rise buildings or areas with unstable water pressure.

[0043] In this invention, the water flow paths in both manual and electronic control modes are roughly the same, and the water flows through the same water channel. This design minimizes the resistance differences between the different flow channels in the two water outlet modes, so that the water flow in both modes is only affected by the characteristics of the same flow channel and the water pressure. The test variable is singular and controllable. In contrast, in the prior art, due to the inherent structural differences between the two flow channels, even if other test conditions are the same, the manual flow rate is prone to deviating significantly from the inductive flow rate by more than 10%, resulting in significant fluctuations in the test results.

[0044] Reference Figure 9 and Figure 10As 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 swings to the third angle, at which point the water output in the manual control mode is maximized. The first angle, the second angle, and the third angle increase sequentially.

[0045] 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" by simply swinging the control component 5 with one hand, without the need for additional buttons or switches.

[0046] 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.

[0047] 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.

[0048] 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, using the central axis as a reference, which facilitates temperature adjustment.

[0049] 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.

[0050] When the adjustable water volume valve core is in the electronic control mode, the magnet 36 is identified by the magnetic sensor 44, and the magnetic sensor 44 transmits the signal to the controller. The controller controls the probe and the solenoid valve 13 to be in the 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 block or open the second pressure relief channel through the hand-held signal. When the adjustable water volume valve core is in manual control mode, the magnet 36 cannot be recognized by the magnetic sensor 44. The controller controls the solenoid valve 13 to be in a non-operating state, and the controller controls the solenoid valve 13 to isolate the second pressure relief channel 1D. Since the solenoid valve 13 is in a non-operating state in manual control mode, it ensures that the user will not trigger the second pressure relief channel 1D by means of a probe or other means.

[0051] When the user is unaware that the faucet is a dual-control faucet that can control water flow in both manual and electric modes, 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 control mode, since the controller automatically controls the solenoid valve 13 to close the second pressure relief channel 1D during the manual control mode, the electric control mode is in the water-off state, and there is no need to control the solenoid valve 13 again through the probe to turn off the water.

[0052] 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 second 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.

[0053] On the other hand, this utility model provides a faucet, including a pressure relief faucet valve core as described in any of the preceding claims.
