Description

Technical Field

[0001] The present invention relates to the technical field of faucet valve cores, and in particular to a dual-control mixing faucet valve core and a faucet. Background Art

[0002] European Patent Document EP2686495B1 discloses a sanitary fitting having a fitting housing and a control unit. This patent document primarily discloses the following: It comprises a water pipe connection, comprising a fitting housing having a water outlet commonly assigned to at least two water inlets, wherein at least two water pipes guided therethrough are provided with water pipes parallel to the water flow path between the two or more water inlets and the common water outlet, wherein each of the parallel water pipes is provided with a control element for opening and closing the water flow path, wherein the control element is configured such that when the control element is located in one of the parallel water lines, one or more other control elements in one or more other parallel water lines are closed, and wherein a mixing valve is configured such that mixed water flows in the common water pipe or in bypasses serving as parallel water pipes, wherein the water pipes and the bypasses meet at a first branching point upstream of the water outlet, as viewed in the direction of water flow, and wherein the two water pipes diverge at a second branching point, which is arranged downstream of the mixing valve, so that the temperatures of the two water lines can be mixed by the mixing valve.

[0003] However, in the above patent document, since the second branch point is set downstream of the mixing valve, that is, outside the mixing valve, this will make the overall structure more complicated and require multiple pipes to be connected. The connection of multiple pipes not only takes up a large space, but also easily causes water leakage due to loose connection of pipes, thereby reducing the reliability and service life of the faucet.

[0004] Moreover, when the control element used (such as a solenoid valve, etc.) is powered off, the user cannot perform timely switching or water cut-off operations through manual control, which will cause the faucet to leak, which not only wastes water resources, but may also cause adverse effects such as residual water stains on the surrounding environment. In severe cases, it may even damage the faucet itself or other related facilities, greatly affecting the normal use of the faucet and user satisfaction. Summary of the Invention

DETAILED DESCRIPTION

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. It should be noted that the description of these embodiments is intended to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

[0035] Reference Figures 1 to 12 As shown, a double-control mixing faucet valve core includes a fixing component 1, the fixing component 1 is provided with a water supply channel 1a and a water outlet channel 1b, and also includes an adjusting component 2, the fixing component 1 is provided with an installation cavity 1c, the adjusting component 2 is provided with a manual-controlled water mixing chamber 2a, an electric-controlled water mixing chamber 2b and a blocking portion 2c. By moving the adjusting component 2 in the installation cavity 1c, the manual-controlled water mixing chamber 2a, the electric-controlled water mixing chamber 2b or the blocking portion 2c is selected to connect with the water supply channel 1a, so that the double-control mixing faucet valve core of the present invention is switched between manual control mode, electric control mode and closed mode.

[0036] Compared to the design in European Patent Document EP2686495B1, which places the second water diversion node downstream of the mixing valve, the present invention, because a manual-controlled water mixing chamber 2a and an electrically controlled water mixing chamber 2b are formed in the dual-control mixing faucet valve core, creatively integrates the water diversion node into the dual-control mixing faucet valve core, making the entire valve core structure more compact and eliminating the need for multiple pipes for connection, thus avoiding the risk of water leakage caused by loose pipe connections. The overall structure is more compact and also reduces the complexity of subsequent maintenance. In addition, when the solenoid valve fails or the power is cut off, the user can switch the dual-control mixing faucet valve core to manual control mode or closed mode by moving the adjustment component 2 to prevent water leakage from the faucet.

[0037] Preferably, there are two water supply channels 1a, which are used to connect to an external cold water pipe and an external hot water pipe, respectively. As another embodiment, there is only one water supply channel 1a. For example, when there is only one water supply channel 1a, it can be connected to an external water purifier to achieve water supply.

[0038] The user moves the adjustment component 2, and when the blocking portion 2c is aligned with the water supply channel 1a, the valve core of the dual-control mixing faucet of the present invention is in the closed mode. At this time, neither the manual control mode nor the electric control mode can control the water outlet. When the manually controlled water mixing chamber 2a is connected to the water supply channel 1a, the valve core of the dual-control mixing faucet of the present invention is in the manual control mode, and the water outlet temperature and water volume of the valve core of the dual-control mixing faucet of the present invention are adjusted by the manual control mode. When the electrically controlled water mixing chamber 2b is connected to the water supply channel 1a, the valve core of the dual-control mixing faucet of the present invention is in the electric control mode. Through the above design, when the solenoid valve 3 is damaged, the user can switch it to the closed mode or manual control mode, thereby avoiding water leakage caused by the solenoid valve 3.

[0039] Specifically, the regulating assembly 2 includes a diaphragm 21, a pressure relief chamber 2d is provided at the back end of the diaphragm 21, and the manually-controlled water mixing chamber 2a and the electrically-controlled water mixing chamber 2b are provided at the front end of the diaphragm 21, one end of the pressure relief chamber 2d is connected to the electrically-controlled water mixing chamber 2b, and the other end of the pressure relief chamber 2d is connected to the water outlet channel 1b.

[0040] Thus, when the dual-control mixing faucet valve core of the present invention is in the electric control mode, external water flows through the water supply channel 1a into the electrically controlled mixing chamber 2b for mixing. The water flow in the electrically controlled mixing chamber 2b then pushes the diaphragm 21 open toward the pressure relief chamber 2d, allowing the water in the electrically controlled mixing chamber 2b to enter the manually controlled mixing chamber 2a and then flow out through the water outlet channel 1b. During the process of pushing the diaphragm 21 open, the water in the pressure relief chamber 2d is discharged through the water outlet channel 1b for pressure relief, thereby establishing communication between the electrically controlled mixing chamber 2b and the manually controlled mixing chamber 2a.

[0041] More specifically, the adjusting component 2 is provided with a first pressure relief channel 2e, and the fixing component 1 is provided with a second pressure relief channel 1d. The other end of the first pressure relief channel 2e is connected to the pressure relief chamber 2d, and the other end of the first pressure relief channel 2e is connected to the water outlet channel 1b. When the double-control mixing faucet valve core is in the electric control mode, the first pressure relief channel 2e and the second pressure relief channel 1d are connected; the adjusting component 2 is also provided with a third pressure relief channel 2f, and the third pressure relief channel 2f is used to connect the pressure relief chamber 2d and the electrically controlled mixing water chamber 2b; it also includes a solenoid valve 3, and the solenoid valve 3 is provided with a plug 31, and the plug 31 can be switched between isolating or staggering the second pressure relief channel 1d position.

[0042] Therefore, when the valve core of the dual-control mixer tap of the present invention is in the electric control mode, refer to Figure 6 、 Figure 7 、 Figure 9 、 Figure 10 、 Figure 11As shown, the red arrow indicates the direction of external water flowing through the valve core of the dual-control mixing faucet of the present invention for temperature adjustment, and the blue arrow indicates the direction of water flowing into the pressure relief chamber 2d. When the user needs water, the user's hand-lifting action is recognized by the hand-lifting sensor, which controls the plug 31 of the solenoid valve 3 to move, causing the plug 31 to stagger away from the second pressure relief channel 1d. At this time, the water flow in the pressure relief chamber 2d will be relieved through the first pressure relief channel 2e, the second pressure relief channel 1d, and the water outlet channel 1b in sequence. When the user does not need water, the user's hand-lifting action is recognized by the hand-lifting sensor, which controls the plug 31 of the solenoid valve 3 to move, causing the plug 31 to block the second pressure relief channel 1d. The water flow in the electrically controlled mixing chamber 2b enters the pressure relief chamber 2d through the third pressure relief channel 2f. The water pressure in the pressure relief chamber 2d causes the diaphragm 21 to separate the electrically controlled mixing chamber 2b from the manually controlled mixing chamber 2a, and the faucet stops discharging water.

[0043] The second support 23 is provided with a water stop surface 231. When the valve core of the dual-control mixing faucet of the present invention is in the electric control mode, the second pressure relief channel 1d is blocked by the plug 31 of the solenoid valve 3, and the pressure relief chamber 2d cannot relieve pressure. Under the action of water pressure, when the diaphragm 21 abuts against the water stop surface 231, the manually controlled water mixing chamber 2a and the electrically controlled water mixing chamber 2b are in a cut-off state, thereby stopping the faucet from discharging water.

[0044] Reference Figure 2 and Figure 3 As shown, when the valve core of the dual-control mixing faucet of the present invention is in the closed mode, since the blocking portion 2c is aligned with the water supply channel 1a, the external water flow cannot enter the manual mixing chamber 2a or the electric mixing chamber 2b, and thus water cannot be discharged, thereby avoiding the problem in the prior art that the faucet leaks when the solenoid valve 3 is damaged.

[0045] Reference Figure 4 and Figure 5 As shown, the red arrow indicates the direction of external water flowing through the valve core of the dual-control mixing faucet of the present invention for temperature adjustment. When the valve core of the dual-control mixing faucet of the present invention is in manual control mode, even if the user's hand is captured by the sensing window, triggering the plug 31 of the solenoid valve 3 to stagger the second pressure relief channel 1d, the first pressure relief channel 2e and the second pressure relief channel 1d are misaligned and cannot be connected. At this time, the pressure relief chamber 2d cannot relieve pressure, and the diaphragm 21 cannot move under the action of water pressure, so that the electrically controlled mixing chamber 2b and the manually controlled mixing chamber 2a are disconnected. Therefore, the external cold water and hot water mix in the manually controlled mixing chamber 2a through the water supply channel 1a and then flow out through the water outlet channel 1b.

[0046] Reference Figure 4 and Figure 5As shown, when the valve core of the dual-control mixing faucet of the present invention is in manual control mode, the user cannot control the water flow of the faucet through the solenoid valve 3, thereby avoiding the problem that the hand movement of the user is captured by the sensing window when the hand moves toward the control part 4, thereby triggering the water path that senses the water flow to start flowing water.

[0047] Through the arrangement design of the above channels and chamber positions, the structure of the entire valve core is made more compact, which is conducive to miniaturization design and is suitable for small kitchen or bathroom spaces.

[0048] Reference Figure 2 and Figure 9 As shown, the regulating assembly 2 includes a first support 22, a second support 23 and a third support 24 which are stacked in sequence, the diaphragm 21 is clamped between the first support 22 and the second support 23, and the closed space of the first support 22 and the second support 23 forms the pressure relief chamber 2d. A spring 25 is provided between the diaphragm 21 and the first support 22, and the spring 25 is provided with a needle tip 251 which is inserted into the third pressure relief channel 2f.

[0049] As diaphragm 21 moves, it drives spring 25, causing needle tip 251 to reciprocate through third pressure relief passage 2f. This prevents impurities in the water, such as sand, from clogging third pressure relief passage 2f and causing failure of pressure relief chamber 2d. Spring 25 also accelerates and maintains diaphragm 21 against water-stop surface 231.

[0050] Specifically, the regulating assembly 2 also includes a diaphragm bracket 26. One end of the diaphragm member 21 passes through the diaphragm bracket 26 and can be raised and lowered in the manual water mixing chamber 2a. The manual water mixing chamber 2a guides the movement of the diaphragm member 21. The spring 25 is arranged between the first support 22 and the diaphragm bracket 26, and one end is inserted into the diaphragm bracket 26, thereby limiting the displacement path of the spring 25.

[0051] The manually controlled water mixing chamber 2a extends through the first support 22 and the second support 23, while the electrically controlled water mixing chamber 2b extends through the first support 22 and the second support 23. The second support 23 and the third support 24 can be integrally formed or independently manufactured. The third pressure relief channel 2f extends through the diaphragm support 26, while the first pressure relief channel 2e extends through the first support 22 and the second support 23. The first pressure relief channel 2e and the electrically controlled water mixing chamber 2b are arranged on either side of the central axis of the regulating assembly 2. The second pressure relief channel 1d is U-shaped and extends through the valve core seat 11 of the fixed assembly 1.

[0052] Reference Figure 4 and Figure 5As shown, the bottom of the third support 24 is provided with a water mixing port 2a1, which gradually widens in size toward the sealing portion 2c. Specifically, the opening of the manual water mixing chamber 2a, which penetrates the adjustment assembly 2 and communicates with the outside, constitutes the water mixing port 2a1. Due to the unique shape of the water mixing port 2a1, when the adjustment assembly 2 is switched from the position corresponding to manual control mode to the position corresponding to closed mode, the area of ​​communication between the water mixing port 2a1 and the water outlet channel 1b gradually decreases, gradually reducing the water output from the dual-control mixing faucet valve core of the present invention, ultimately shutting off the water flow, which conforms to the user's daily water shut-off habits.

[0053] Reference Figure 1 、 Figure 2 and Figure 8 As shown, the fixed assembly 1 includes a valve core seat 11 and a partition 12 fixedly connected to the valve core seat 11. The two water supply channels 1a passing through the valve core seat 11 form two water supply channels 1a1, and the two water supply channels 1a passing through the partition 12 form two fan-shaped water supply channels 1a2. By rotating the adjustment assembly 2, when the connection area between one of the water supply channels 1a2 and the manual mixing chamber 2a or the electric mixing chamber 2b increases, the connection area between the other water supply channel 1a2 and the manual mixing chamber 2a or the electric mixing chamber 2b will decrease. Through the two fan-shaped water supply channels 1a2, when the adjustment assembly 2 is rotated, the ratio of cold water and hot water entering the above mixing chambers is adjusted, ultimately achieving the adjustment of the water outlet temperature.

[0054] Through the above structural design, the user can control the water output by moving the adjustment component 2 horizontally, and the user can adjust the water temperature by rotating the adjustment component 2. The operation method is the same as that of a traditional manual faucet, which is in line with user habits.

[0055] To facilitate user control of the adjustment assembly 2, a control member 4 is included. This control member 4 is used to drive the adjustment assembly 2 to move laterally or rotate within the mounting cavity 1c. The user can rotate the control member 4 to control the rotation of the adjustment assembly 2 within the mounting cavity 1c, thereby adjusting the outlet water temperature of the dual-control mixing faucet valve core. By pulling the control member 4 laterally, the user can control the lateral movement of the adjustment assembly 2 within the mounting cavity 1c, switching the dual-control mixing faucet valve core between manual control mode, electric control mode, and closed mode.

[0056] In order to connect the operating member 4 with the adjustment component 2, the fixing component 1 also includes a shell 13 and a connecting seat 14 rotatably connected to the shell 13. The lower end of the connecting seat 14 is provided with a guide groove 141, and the upper end of the adjustment component 2 is embedded in the guide groove 141. The operating member 4 is swingably connected to the connecting seat 14, and the operating member 4 passes through the connecting seat 14 and is embedded in the adjustment component 2.

[0057] Specifically, a rotating shaft 41 passes through the connecting seat 14 and the operating member 4, achieving a swingable connection between the two. The first support 22 of the adjustment assembly 2 is provided with a groove 221 for the operating member 4 to be inserted into. The upper end of the first support 22 is inserted into the guide groove 141, and the upper end of the operating member 4 extends through the housing 13. The user controls the swinging of the operating member 4 to move the adjustment assembly 2 to different positions in the installation cavity 1c, thereby selecting the manually controlled water mixing chamber 2a, the electrically controlled water mixing chamber 2b, or the blocking portion 2c to connect with the water supply channel 1a, thereby switching the valve core of the dual-control mixing faucet of the present invention between manual control mode, electrically controlled mode, and closed mode.

[0058] The housing 13 is fastened to the valve core seat 11, and the partition 12 is embedded in the upper end of the valve core seat 11. A first sealing gasket 15 is sandwiched between the partition 12 and the valve core seat 11. This first sealing gasket 15 prevents water from seeping into the installation cavity 1c from the connection between the partition 12 and the valve core seat 11. The space between the connecting seat 14 and the partition 12 constitutes the installation cavity 1c, and the adjustment assembly 2 can move laterally along the installation cavity 1c.

[0059] A second sealing gasket 27 is provided between the second support 23 and the third support 24 to prevent water from seeping into the mounting cavity 1c from the connection between the second support 23 and the third support 24. A sealing ring 28 is provided between the first support 22 and the second support 23 to prevent water from seeping into the mounting cavity 1c from the connection between the first support 22 and the second support 23.

[0060] A feedback structure is provided between the connecting seat 14 and the adjusting component 2. When the movable adjusting component 2 is translated to trigger the feedback structure, the valve core of the dual-control mixing faucet of the present invention is in a closed mode.

[0061] Reference Figure 12 As shown, the feedback structure includes at least two first elastic columns 5 and two second elastic columns 6. The first elastic columns 5 and the second elastic columns 6 are preferably made of a deformable material such as rubber. The two first elastic columns 5 are respectively disposed on the inner walls of the guide groove 141 of the connecting base 14, and the two second elastic columns 6 are respectively disposed on both sides of the first support 22.

[0062] Reference Figure 12 As shown, when the adjustment assembly 2 is moving, the tactile contact between the first elastic column 5 and the second elastic column 6 indicates that the blocking portion 2c of the adjustment assembly 2 is docked with the water supply channel 1a, indicating that the dual-control mixing faucet valve core of the present invention is in the closed mode. When the user controls the dual-control mixing faucet valve core of the present invention to switch between manual control mode and electric control mode, the maximum deformation resistance generated by the first elastic column 5 and the second elastic column 6 must be overcome to prevent the user from accidentally touching the control member 4 and causing the dual-control mixing faucet valve core to switch control modes.

[0063] As another embodiment (not shown in the figure), the feedback structure may be: a spring pin and a recessed structure respectively provided on the adjustment component 2 and the first support 22 cooperate with each other to provide feedback through the telescopic elastic movement of the spring pin and the recessed structure.

[0064] Reference Figures 2 to 7 As shown, the manual-controlled water mixing chamber 2a and the electric-controlled water mixing chamber 2b are located on both sides of the blocking portion 2c. Therefore, when switching control modes, the user will inevitably experience the shutdown mode. The user can easily and accurately determine that the control mode switch is successful by observing the cessation of water flow, without the need for additional operations or complicated operation prompts, thus lowering the user's usage threshold.
