Description

Technical Field

[0001] The present invention relates to the technical field of faucet valve cores, and particularly 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. The main disclosures in this patent document are as follows: It includes a water pipe joint, which includes a fitting housing, having an outlet commonly assigned to at least two inlets, wherein at least two water pipes guided therein are provided with water pipes parallel to the water flow path between two or more inlets and a common outlet, wherein, in each of the parallel-guided water pipes, a control element for opening and closing the water flow path is provided, wherein a control is provided for controlling the control element such that when the control element is in one of the parallel water lines, when opened, one or more of the other control elements in one or more of the other parallel water pipe lines are closed, and wherein a mixing valve is arranged such that the mixed water flows in the common water pipe or in a bypass as a parallel water pipe, wherein, upstream of the outlet, as viewed in the direction of water flow, the water pipe and the bypass converge at a first branch point, and wherein the two water pipes are separated at a second branch point, the second branch point being arranged downstream of the mixing valve such that the temperature in the two water pipe lines can be mixed by the mixing valve.

[0003] However, in the above patent document, since its second branch point is arranged downstream of the mixing valve, that is, outside the mixing valve, this will result in a relatively complex overall structure, requiring multiple pipe fittings for connection. The connection of multiple pipe fittings not only occupies a large space but also easily causes a potential leakage problem due to the loose connection of the pipe fittings, reducing the reliability and service life of the faucet.

[0004] And when a power failure occurs in the control element used (such as when the control element is a solenoid valve, etc.), the user cannot perform timely switching or water cut-off operations manually, which will cause the faucet to leak water. This not only causes waste of water resources but also may cause adverse effects such as water stains remaining 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

[0005] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a dual-control mixing faucet valve core and a faucet to solve the problems mentioned in the above background art section.

[0006] The present invention is achieved through the following technical solutions: A double-control mixing faucet valve core comprises a fixing component, wherein the fixing component is provided with a water supply channel and a water outlet channel, and further comprises an adjusting component, wherein an installation cavity is provided in the fixing component, and the adjusting component is provided with a manual-controlled water mixing chamber, an electric-controlled water mixing chamber and a blocking portion. By moving the adjusting component in the installation cavity, the manual-controlled water mixing chamber, the electric-controlled water mixing chamber or the blocking portion is selected to be docked with the water supply channel, so that the double-control mixing faucet valve core can be switched between a manual control mode, an electric control mode and a closed mode.

[0007] Furthermore, the regulating assembly includes a diaphragm, a pressure relief chamber is provided at the back end of the diaphragm, and the manually-controlled water mixing chamber and the electrically-controlled water mixing chamber are provided at the front end of the diaphragm, one end of the pressure relief chamber is connected to the electrically-controlled water mixing chamber, and the other end of the pressure relief chamber is connected to the water outlet channel.

[0008] Further, the regulating component is provided with a first pressure relief channel, the fixing component is provided with a second pressure relief channel, the other end of the first pressure relief channel is communicated with the pressure relief chamber, the other end of the first pressure relief channel is communicated with the water outlet channel, and when the double-control mixing faucet valve core is in the electric control mode, the first pressure relief channel and the second pressure relief channel are communicated; The regulating assembly is further provided with a third pressure relief channel, and the third pressure relief channel is used to connect the pressure relief chamber and the electrically controlled water mixing chamber; It also includes a solenoid valve, which is provided with a plug, and the plug can be switched between isolating or staggering the position of the second pressure relief channel.

[0009] Furthermore, the regulating assembly includes a first support, a second support and a third support which are sequentially stacked, the diaphragm member is clamped between the first support and the second support, the closed space between the first support and the second support constitutes the pressure relief chamber, a spring is provided between the diaphragm member and the first support, and the spring is provided with a needle tip portion which is inserted into the third pressure relief channel.

[0010] Furthermore, the second support is provided with a water stop surface, and when the diaphragm member abuts against the water stop surface, the manually controlled water mixing chamber and the electrically controlled water mixing chamber are in a partitioned state.

[0011] Furthermore, the fixed component includes a valve core seat, a partition fixedly connected to the valve core seat, the two water supply channels passing through the valve core seat constitute two water supply channels, and the two water supply channels passing through the partition constitute two fan-shaped water supply channels. By rotating the adjusting component, when the connection area between one of the water supply channels and the manually controlled water mixing chamber or the electrically controlled water mixing chamber increases, the connection area between the other water supply channel and the manually controlled water mixing chamber or the electrically controlled water mixing chamber will become smaller.

[0012] Further, it further includes a control member for driving the adjustment assembly to move horizontally or rotate in the installation cavity.

[0013] Further, the fixing assembly further includes a housing and a connecting seat rotatably connected to the housing. A guiding groove is provided at the lower end of the connecting seat, and the upper end of the adjustment assembly is embedded in the guiding groove. The control member is swingably connected to the connecting seat, and the control member passes through the connecting seat and is embedded in the adjustment assembly.

[0014] Further, the manual mixing chamber and the electric control mixing chamber are arranged on both sides of the blocking portion.

[0015] On the other hand, the present invention provides a faucet including a dual-control mixing faucet valve core as described in any one of the above.

[0016] The beneficial effects of the present invention are as follows: A dual-control mixing faucet valve core includes a fixing assembly provided with a water supply channel and a water outlet channel, and further includes an adjustment assembly. An installation cavity is provided in the fixing assembly, and the adjustment assembly is provided with a manual mixing chamber, an electric control mixing chamber, and a blocking portion. By moving the adjustment assembly in the installation cavity, either the manual mixing chamber, the electric control mixing chamber, or the blocking portion is selectively docked with the water supply channel, enabling the dual-control mixing faucet valve core to switch between a manual control mode, an electric control mode, and a closed mode. During use, by moving the adjustment assembly; when the manual mixing chamber is in communication with the water supply channel, the dual-control mixing faucet valve core is in the manual control mode; when the electric control mixing chamber is in communication with the water supply channel, the dual-control mixing faucet valve core is in the electric control mode; when the blocking portion is aligned with the water supply channel, since the water flow in the water supply channel cannot enter the manual mixing chamber or the electric control mixing chamber, the dual-control mixing faucet valve core is in the closed mode, and neither the manual control mode nor the electric control mode can control the water outlet. With the above structure, it is possible to avoid the water leakage of the faucet when the solenoid valve is damaged in the prior art. Description of the Drawings

[0030] To make the purposes, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention. It should be noted here that the descriptions of these embodiments are used to help understand the present invention, but do not constitute a limitation to the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0031] Referring to Figures 1 to 12 As shown, a dual-control hybrid faucet valve core includes a fixed component 1, the fixed component 1 is provided with a water supply channel 1a and a water outlet channel 1b, and further includes an adjusting component 2. An installation cavity 1c is provided in the fixed component 1, and the adjusting component 2 is provided with a manual mixing chamber 2a, an electric control mixing chamber 2b and a blocking part 2c. By moving the adjusting component 2 in the installation cavity 1c, the manual mixing chamber 2a, the electric control mixing chamber 2b or the blocking part 2c is selectively connected to the water supply channel 1a, so that the dual-control hybrid faucet valve core of the present invention can be switched between a manual control mode, an electric control mode and a closed mode.

[0032] Compared with the design in European patent document EP2686495B1 where the second water distribution node is arranged downstream of the mixing valve. In the present invention, since the manual mixing chamber 2a and the electric control mixing chamber 2b are formed in the dual-control hybrid faucet valve core, the water distribution node is creatively built into the dual-control hybrid faucet valve core, making the structure of the entire valve core more compact, and there is no need for multiple pipe fittings to be connected, avoiding potential water leakage caused by loose connection of pipe fittings. The overall structure is more compact, and at the same time, the complexity of later maintenance is reduced. And when the solenoid valve fails or loses power, the user can switch the dual-control hybrid faucet valve core to the manual control mode or the closed mode by moving the adjusting component 2, avoiding water leakage from the faucet.

[0033] Preferably, the number of the water supply channels 1a is two, and the two water supply channels 1a are respectively used to connect an external cold water pipe and an external hot water pipe. As another embodiment, the number of the water supply channels 1a is one. For example, when the number of the water supply channels 1a is one, it can be connected to an external water purifier to achieve water supply.

[0034] When the user moves the adjusting component 2, when the blocking part 2c is aligned with the water supply channel 1a, the dual-control hybrid faucet valve core 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 output. When the manual mixing chamber 2a is communicated with the water supply channel 1a, the dual-control hybrid faucet valve core of the present invention is in the manual control mode, and the water output temperature and water output of the dual-control hybrid faucet valve core of the present invention are adjusted through the manual control mode. When the electric control mixing chamber 2b is communicated with the water supply channel 1a, the dual-control hybrid faucet valve core 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 the manual control mode, thereby avoiding water leakage from the faucet due to the solenoid valve 3.

[0035] 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.

[0036] Thus, when the valve core of the dual-control mixing faucet of the present invention is in the electric control mode, the external water flows from the water supply channel 1a into the electric-controlled water mixing chamber 2b for mixing, and then the water flow of the electric-controlled water mixing chamber 2b pushes the diaphragm 21 toward the pressure relief chamber 2d, so that the water flow of the electric-controlled water mixing chamber 2b enters the manual-controlled water mixing chamber 2a, and then flows out through the water outlet channel 1b. In the process of pushing the diaphragm 21, the water flow of the pressure relief chamber 2d is discharged by the water outlet channel 1b for pressure relief, so that the electric-controlled water mixing chamber 2b and the manual-controlled water mixing chamber 2a are connected to each other.

[0037] 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; and 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 position of the second pressure relief channel 1d.

[0038] Therefore, when the valve core of the dual-control mixer tap of the present invention is in the electric control mode, Figure 6 , Figure 7 , Figure 9 , Figure 10 , Figure 11As shown, the red arrow is the flow direction of the external water flowing through the valve core of the dual-control mixing faucet of the present invention for temperature adjustment, and the blue arrow is the flow direction of the water flow in the pressure relief chamber 2d. When the user needs to use water, the user's hand-lifting action is recognized by the hand-lifting sensor, and then the plug 31 of the solenoid valve 3 is controlled to move, so that the plug 31 is offset from the second pressure relief channel 1d. At this time, the water flow in the pressure relief chamber 2d will pass through the first pressure relief channel 2e, the second pressure relief channel 1d and the water outlet channel 1b in sequence for pressure relief. When the user does not need to use water, the user's hand-lifting action is recognized by the hand-lifting sensor, and then the plug 31 of the solenoid valve 3 is controlled to move, so that the plug 31 cuts off the second pressure relief channel 1d, and the water flow in the electrically controlled mixing water chamber 2b enters the pressure relief chamber 2d from the third pressure relief channel 2f. Through the water pressure of the pressure relief chamber 2d, the diaphragm 21 cuts off the electrically controlled mixing water chamber 2b and the manually controlled mixing water chamber 2a, and the faucet stops discharging water.

[0039] The second support 23 is provided with a water stop surface 231. When the valve core of the double-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.

[0040] Reference Figure 2 and Figure 3 As shown, when the valve core of the double-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-controlled water mixing chamber 2a or the electric-controlled water mixing chamber 2b, and thus water cannot be discharged, thereby avoiding the faucet leakage when the solenoid valve 3 is damaged in the prior art.

[0041] Reference Figure 4 and Figure 5 As shown, the red arrow is the flow 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, the plug 31 of the triggering solenoid valve 3 staggers the second pressure relief channel 1d, but the first pressure relief channel 2e and the second pressure relief channel 1d are misaligned and cannot be conducted. At this time, the pressure relief chamber 2d cannot be depressurized, and the diaphragm 21 cannot move under the action of water pressure, so that the electric control mixing chamber 2b and the manual control mixing chamber 2a cannot be connected. Therefore, the external cold water and hot water are mixed in the manual control mixing chamber 2a through the water supply channel 1a, and then flow out through the water outlet channel 1b.

[0042] Reference Figure 4 and Figure 5As shown, when the double-control hybrid faucet valve core of the present invention is in the manual control mode, the user cannot control the faucet water outlet through the solenoid valve 3, thus avoiding the problem that during the process of the user's hand moving towards the control member 4, the hand movement is captured by the sensing window, triggering the waterway for sensing water outlet to also start discharging water.

[0043] Through the layout design of the above various 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 narrow kitchen or bathroom spaces.

[0044] Refer to Figure 2 and Figure 9 As shown, the adjusting assembly 2 includes a first support 22, a second support 23, and a third support 24 arranged in layers in sequence. The diaphragm member 21 is clamped between the first support 22 and the second support 23. The closed space between the first support 22 and the second support 23 forms the pressure relief chamber 2d. A spring 25 is provided between the diaphragm member 21 and the first support 22, and the spring 25 is provided with a needle tip portion 251 inserted into the third pressure relief channel 2f.

[0045] During the movement of the diaphragm member 21, it will drive the spring 25 to move, causing the needle tip portion 251 to reciprocally penetrate the third pressure relief channel 2f, thereby preventing impurities in the water flow, such as sand, from blocking the third pressure relief channel 2f and resulting in the failure of the pressure relief chamber 2d. And the spring 25 also plays a role in accelerating and maintaining the contact between the diaphragm member 21 and the water stop surface 231.

[0046] Specifically, the adjusting assembly 2 further includes a diaphragm bracket 26. One end of the diaphragm member 21 passes through the diaphragm bracket 26 and can move up and down in the manual mixing water chamber 2a. The manual mixing water chamber 2a plays a guiding role in 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.

[0047] Among them, the manual mixing water chamber 2a penetrates through the first support 22 and the second support 23, the electric control mixing water chamber 2b penetrates through the first support 22 and the second support 23. The second support 23 and the third support 24 can be integrally processed or made by separate independent processing. The third pressure relief channel 2f penetrates through the diaphragm bracket 26, the first pressure relief channel 2e penetrates through the first support 22 and the second support 23. The first pressure relief channel 2e and the electric control mixing water chamber 2b are respectively arranged on both sides of the central axis of the adjusting assembly 2. The second pressure relief channel 1d is arranged in a U shape through the valve core seat 11 of the fixing assembly 1.

[0048] Refer to Figure 4 and Figure 5As shown, a mixing water transition port 2a1 with a gradually increasing opening towards the plugging portion 2c is provided at the bottom of the third support 24, that is, the opening of the through-adjustment component 2 of the manual control mixing water chamber 2a and communicating with the outside constitutes the mixing water transition port 2a1. Through the special shape of the mixing water transition port 2a1, when the adjustment component 2 is switched from the corresponding position in the manual control mode to the corresponding position in the closed mode, the communication area between the mixing water transition port 2a1 and the water outlet channel 1b will gradually shrink, so that the water output of the double-control mixing faucet valve core of the present invention will gradually decrease and finally close the water outlet, which conforms to the user's daily water closing operation habits.

[0049] Referring to Figure 1 , Figure 2 and Figure 8 As shown, the fixing component 1 includes a valve core seat 11, a partition 12 fixedly connected to the valve core seat 11. The parts where the two water supply channels 1a penetrate through the valve core seat 11 form two water supply first channels 1a1, and the parts where the two water supply channels 1a penetrate through the partition 12 form two fan-shaped water supply second channels 1a2. By rotating the adjustment component 2, when the communication area between one of the water supply second channels 1a2 and the manual control mixing water chamber 2a or the electric control mixing water chamber 2b increases, the communication area between the other water supply second channel 1a2 and the manual control mixing water chamber 2a or the electric control mixing water chamber 2b will become smaller. Through the two fan-shaped water supply second channels 1a2, when the adjustment component 2 is rotated, the proportion of cold water and hot water entering the above mixing water chamber will be adjusted, and finally the adjustment of the water outlet temperature is realized.

[0050] Through the above structural design, the user can control the water output by horizontally moving the adjustment component 2, and the user can adjust the water outlet temperature by rotating the adjustment component 2. The operation method is the same as that of the traditional manual faucet, which conforms to the user's usage habits.

[0051] In order to facilitate the user to control the adjustment component 2, a control member 4 is further included. The control member 4 is used to drive the adjustment component 2 to horizontally move or rotate in the installation cavity 1c. Among them, the user can control the adjustment component 2 to rotate in the installation cavity 1c by rotating the control member 4, so as to adjust the water outlet temperature of the double-control mixing faucet valve core of the present invention. The user can horizontally move the control member 4 to control the adjustment component 2 to horizontally move in the installation cavity 1c, so that the double-control mixing faucet valve core of the present invention is switched between the manual control mode, the electric control mode and the closed mode.

[0052] In order to connect the control member 4 with the adjustment component 2, the fixing component 1 further includes a housing 13 and a connecting seat 14 rotatably connected to the housing 13. A guide groove 141 is provided at the lower end of the connecting seat 14. The upper end of the adjustment component 2 is embedded in the guide groove 141. The control member 4 is swingably connected to the connecting seat 14, and the control member 4 passes through the connecting seat 14 and is embedded in the adjustment component 2.

[0053] Specifically, the connecting seat 14 and the control member 4 are swingably connected by passing through the rotating shaft 41. The first support 22 of the adjusting assembly 2 is provided with a groove 221 for the control member 4 to be embedded. The upper end of the first support 22 is embedded in the guiding groove 141, and the upper end of the control member 4 passes through the housing 13. By controlling the swing of the control member 4, the user can move the adjusting assembly 2 to different positions in the installation cavity 1c, so as to selectively connect the manual mixing chamber 2a, the electric control mixing chamber 2b or the blocking portion 2c with the water supply channel 1a, enabling the dual-control mixing faucet valve core of the present invention to switch between the manual control mode, the electric control mode and the closed mode.

[0054] Wherein, the housing 13 is snap-connected with the valve core seat 11. The partition 12 is embedded in the upper end of the valve core seat 11, and a first sealing gasket 15 is clamped between the partition 12 and the valve core seat 11 to prevent water from seeping into the installation cavity 1c at 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 adjusting assembly 2 can move horizontally along the installation cavity 1c.

[0055] A second sealing gasket 27 is provided between the second support 23 and the third support 24 to prevent water from seeping into the installation cavity 1c at 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 installation cavity 1c at the connection between the first support 22 and the second support 23.

[0056] A feedback structure is provided between the connecting seat 14 and the adjusting assembly 2. When the adjusting assembly 2 is translated to trigger the feedback structure, the dual-control mixing faucet valve core of the present invention is in the closed mode.

[0057] Refer to 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 deformable materials such as rubber. The two first elastic columns 5 are respectively arranged on the inner walls of both sides of the guiding groove 141 of the connecting seat 14, and the two second elastic columns 6 are respectively arranged on both sides of the first support 22.

[0058] Refer to Figure 12 As shown, when the adjusting assembly 2 is moving, the tactile sensation of the mutual abutment of the first elastic column 5 and the second elastic column 6 indicates that the blocking portion 2c of the adjusting assembly 2 is docked with the water supply channel 1a, that is, 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 the manual control mode and the electric control mode, it is necessary to overcome the maximum deformation resistance generated by the first elastic column 5 and the second elastic column 6 to prevent the user from accidentally touching the control member 4 and causing the switching of the control mode of the dual-control mixing faucet valve core of the present invention.

[0059] As other embodiments (not shown in the figures), the feedback structure may be: spring pins respectively provided on the adjusting assembly 2 and the first support 22 cooperate with the concave structures, and the telescopic springing of the spring pins and the concave structures provides feedback.

[0060] Referring to Figures 2 to 7 As shown, the manual mixing chamber 2a and the electric control mixing chamber 2b are arranged on both sides of the blocking portion 2c. Thus, when the user switches the control mode, the user will inevitably experience the closing mode. The user can conveniently and accurately judge that the control mode switching is successful by observing the intuitive feedback of the stop of water outflow, without additional operations or complex operation prompts, reducing the user's usage threshold.

[0061] Corresponding to the above structure, referring to Figure 12 As shown, the first elastic column 5 is arranged in the central area of the adjusting assembly 2, and the second elastic column 6 is arranged in the central area of the first support 22. When the adjusting assembly 2 moves to the central area of the installation cavity 1c, the first elastic column 5 and the second elastic column 6 are in mutual contact, and the double-control mixing faucet valve core of the present invention is in the closed mode.

[0062] On the other hand, the present invention provides a faucet, including a double-control mixing faucet valve core as described in any one of the above, so that the faucet has the advantages of the above double-control mixing faucet valve core.
