Description

Technical Field

[0001] This utility model relates to the field of faucet valve core technology, specifically to a valve core with dual bottom outlets. Background Technology

[0002] In the field of faucet technology, as people's demands for quality of life increase, faucet valve cores and overall designs are constantly being improved to meet diverse needs. Currently, faucet valve cores are mainly divided into mixing valve cores, diverting valve cores, and multi-channel valve cores. Some products achieve functions such as mixing and diverting water by rotating the handle within a certain angle.

[0003] However, existing technologies have many shortcomings, the most serious of which is the safety hazard. Even though existing faucets are designed with a range of handle rotation angles to control water flow and temperature, in actual use, due to a lack of effective safeguards in the structural design, it is still impossible to avoid the accidental release of all hot water. On the one hand, in sensor mode, it is impossible to determine whether the actual position of the valve stem after the handle is turned will fully open the hot water passage. If a user reaches into the sensing area without warning, and the sensor triggers the water flow, they may be scalded by the release of all hot water. On the other hand, designs with some innovation in valve core function and structure, such as those in patent literature (authorization announcement number CN218543267U), may continue to conduct hot water when the electronic switch or control module malfunctions (such as the sensing unit misinterpreting the signal or the electronic switch malfunctioning). Furthermore, when switching between manual and sensor modes or operating in sensor mode, the sliding and rotating movements of the moving valve plate cannot be precisely coordinated, making it difficult to control the hot water ratio, which can also easily lead to the release of all hot water and scalding the user.

[0004] In summary, existing faucet valve core technology still has significant shortcomings in preventing users from being scalded by unexpectedly hot water. In particular, in sensor mode, it is still impossible to determine whether the valve stem rotation position is in a state of full hot water, and users may be scalded if the faucet is turned on easily.

[0005] Therefore, how to provide a special design with dual water outlets that ensures the valve core can switch to the sensing water outlet mode while preventing the user from over-opening the hot water passage and avoiding accidental outflow of hot water, thus providing a reliable guarantee for the user's safety, is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a valve core that, when switched to the sensing water outlet mode, can effectively ensure that the user cannot open the bottom dual water outlet of the full hot water passage.

[0007] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: the valve core with dual water outlets at the bottom includes a stationary valve plate and a moving valve plate. The moving valve plate is located above the stationary valve plate and can rotate and slide relative to the stationary valve plate. The stationary valve plate is provided with a cold water inlet hole, a hot water inlet hole, a first water outlet hole and a second water outlet hole. The moving valve plate is provided with a mixing chamber, and the mixing chamber is connected to a first mixing port and a second mixing port.

[0008] When the movable valve plate is slidably switched to the first state, the second mixing port and the second outlet are always in a misaligned state. The rotation of the movable valve plate can cause the first mixing port to rotate and cover the cold water inlet and the hot water inlet to adjust the mixing ratio of cold and hot water flowing into the mixing chamber. The first mixing port can communicate with the first outlet. The movable valve plate is constrained above the stationary valve plate and can only rotate within a set angle range, thereby limiting the movable valve plate to rotate to the angle where the first mixing port completely covers the hot water inlet to avoid the first outlet from having all hot water.

[0009] When the moving valve plate slides to the second state, the first mixing port and the first water outlet are always misaligned. The rotation of the moving valve plate can cause the first mixing port to rotate and cover the space between the cold water inlet and the hot water outlet, and the second mixing port can connect to the second water outlet. In the second state, the moving valve plate can adjust the mixing ratio of cold and hot water flowing into the mixing chamber as needed during rotation.

[0010] To optimize the channel layout of the first and second mixing ports so that they can better coordinate between the cold water inlet, the hot water inlet, the first outlet, and the second outlet, preferably, the first and second mixing ports are both opened on the end face of the moving valve plate that is attached to the stationary valve plate and are spaced apart. The first mixing port includes a first inlet area for connecting the first outlet and a second inlet area for connecting the cold water inlet and the hot water inlet when the moving valve plate rotates. The second mixing port is fan-shaped and can correspond to the second outlet when the moving valve plate switches to the second state.

[0011] To further optimize the channel structure of the cold water inlet, hot water inlet, first outlet, and second outlet, and to better connect them between the first mixing port and the second mixing port, preferably, the cold water inlet, hot water inlet, and second outlet all extend circumferentially along the stationary valve plate and form an arc-shaped groove. The outlet ends of the cold water inlet, hot water inlet, first outlet, and second outlet all form an extension area to increase the water receiving area.

[0012] In order to optimize the relative positions and overall layout of the cold water inlet, hot water inlet, first outlet, and second outlet, so that the moving valve plate does not completely cover the hot water inlet within its rotation range and thus avoids the occurrence of hot water, preferably, the first outlet is located in the middle of the stationary valve plate, and the cold water inlet, hot water inlet, and second outlet are distributed at intervals along the circumference of the stationary valve plate and together surround the first outlet.

[0013] To optimize the assembly structure and overall layout of the valve core, preferably, it also includes a valve housing and a valve handle, a rotor, and a dial arranged in sequence. A limiting device is also provided between the valve housing and the rotor to restrict the rotor to rotate only within a set angle range. The valve handle is hinged to the rotor and can reciprocate to drive the dial to move. The dial is constrained at the bottom of the rotor and can rotate with the rotor and slide relative to the rotor. The moving valve plate is fixed to the bottom surface of the dial, and the stationary valve plate is fixed to the bottom of the inner cavity of the valve housing. The bottom of the valve housing is also provided with a cold water inlet corresponding to the cold water inlet, a hot water inlet corresponding to the hot water inlet, a first outlet corresponding to the first outlet, and a second outlet corresponding to the second outlet. The sliding of the moving valve plate is used to switch to the first state or the second state, and the rotation of the moving valve plate is used to adjust the mixing ratio of cold water and hot water.

[0014] To optimize the structure and layout of the limiting device, preferably, the limiting device includes a first limiting wall and a second limiting wall disposed inside the valve housing and spaced apart circumferentially, a third limiting wall formed on the side of the rotor and adapted to the first limiting wall, and a fourth limiting wall adapted to the second limiting wall. When the rotor rotates forward to the first position, the first limiting wall abuts against the third limiting wall to restrict the rotor from continuing to rotate forward. When the rotor rotates in reverse to the second position, the second limiting wall abuts against the fourth limiting wall to restrict the rotor from continuing to rotate in the reverse direction.

[0015] To optimize the overall structure of the valve housing and enable better production and assembly of the entire valve core, preferably, the valve housing includes an upper housing and a valve seat. The upper housing is detachably connected to the valve seat via a detachable structure. The upper end of the valve handle is exposed on the top of the upper housing. The cold water inlet, hot water inlet, first outlet, and second outlet are all located on the valve seat.

[0016] To enable the detachable structure to achieve quick disassembly and quick positioning, preferably, the detachable structure includes a snap groove on the upper housing and a snap fastener on the valve seat that can fit into the snap groove. The upper housing is also provided with a positioning groove, and the valve seat is provided with a positioning block that can fit into the positioning groove.

[0017] In order to better mount the valve handle, rotor and dial on the upper housing, preferably, the upper housing has a through mounting hole, the rotor is rotatably built into the mounting hole, the upper end of the valve handle is exposed on the top of the upper housing to facilitate the valve handle to swing or rotate, and the lower end of the valve handle is connected to the dial to facilitate the dial to move or rotate.

[0018] Compared with the prior art, the advantages of this utility model are as follows: By setting a mixing chamber on the moving valve plate and connecting the mixing chamber to the first mixing port and the second mixing port, when the moving valve plate is switched to the first state, that is, switched to the induction water outlet mode, the moving valve plate is precisely limited during rotation and can only rotate within the set angle range. Combined with the channel structure and arrangement of the first mixing port, the moving valve plate will not be rotated to the angle where the first mixing port completely covers the hot water inlet hole, thereby avoiding the disadvantage of the first water outlet hole being full of hot water. This fundamentally eliminates the possibility of full hot water accidentally flowing out in the induction water outlet mode, effectively solving the safety hazard of scalding users caused by the induction water outlet in the prior art, providing reliable protection for user safety, and greatly reducing the probability of scalding accidents caused by misoperation. At the same time, the moving valve plate can flexibly adjust the mixing ratio of hot and cold water by rotating in different states, whether in manual water outlet mode or induction water outlet mode, to meet the user's needs for different water temperatures, improve the comfort of use, and enhance the user's water experience.

Detailed Implementation

[0033] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0034] Figures 1-14 The diagram shown is a schematic of this embodiment. This embodiment revolves around a valve core with dual bottom outlets, aiming to solve the shortcomings of existing faucet valve cores in preventing accidental hot water from causing scalding to users in the sensing water outlet mode, and to provide users with a safer and more convenient user experience. The component structure, connection method and working principle of the valve core are described in detail below. This improved two-inlet and two-outlet valve core mainly includes a stationary valve plate 1, a moving valve plate 2, a valve body 3, a valve handle 4, a rotor 5 and a dial 6, etc., wherein the stationary valve plate 1 and the moving valve plate 2 are located inside the valve body 1.

[0035] The specific structure and function of the stationary valve plate 1 are as follows: (Reference) Figure 2 and Figure 4 As shown, the stationary valve plate 1 is one of the key components of the valve core, and its structural design directly affects the control and distribution of water flow. The stationary valve plate 1 is carefully designed with a cold water inlet 1a, a hot water inlet 1b, a first outlet 1c, and a second outlet 1d. The cold water inlet 1a, hot water inlet 1b, and second outlet 1d all extend circumferentially along the stationary valve plate 1, forming a unique arc-shaped groove. This arc-shaped groove design has significant advantages, allowing for more precise and flexible control of water flow entry and exit when the moving valve plate 2 rotates relative to it, ensuring the stability and uniformity of the water flow. Simultaneously, to further optimize the water flow effect, the outlet ends of the cold water inlet 1a, hot water inlet 1b, first outlet 1c, and second outlet 1d are all specially designed with an extension area 1e. The function of the extension area 1e is to increase the water receiving area, allowing the water flow to be more evenly dispersed or converged when entering and exiting these holes, effectively reducing water flow resistance and turbulence, and improving the smoothness of the water flow. The first water outlet 1c is located in the middle of the stationary valve plate 1, while the cold water inlet 1a, hot water inlet 1b, and second water outlet 1d are distributed at intervals along the circumference of the stationary valve plate 1, surrounding the outer periphery of the first water outlet 1c. This layout not only makes each water flow channel independent, avoiding interference between water flows, but also enables precise control of different water flow channels through the rotation and sliding of the moving valve plate 2, meeting various water output requirements.

[0036] The specific structure and function of the moving valve plate 2 are as follows: (Reference) Figure 2 and Figure 3As shown, the moving valve plate 2 is located above the stationary valve plate 1 and has the function of rotating and sliding relative to the stationary valve plate 1. This characteristic is the key to realizing multiple water outlet modes and hot and cold water mixing regulation of the valve core. The moving valve plate 2 is provided with a mixing chamber 2a, which is connected to the first mixing port 2a1 and the second mixing port 2a2. The first mixing port 2a1 and the second mixing port 2a2 are both opened on the end face of the moving valve plate 2 that is in contact with the stationary valve plate 1, and are distributed at intervals. Among them, the first mixing port 2a1 has a more complex and ingenious structure. It includes a first inlet area 2a11 and a second inlet area 2a12. When the moving valve plate 2 rotates, the first inlet area 2a11 is responsible for connecting the first outlet hole 1c to ensure that the mixed water can flow out smoothly. The second inlet area 2a12 is used to connect the cold water inlet hole 1a and the hot water inlet hole 1b to realize the introduction of cold and hot water and the regulation of the mixing ratio. The second mixing port 2a2 has a fan-shaped structure. This design allows it to accurately correspond to the second water outlet 1d when the moving valve plate 2 switches to the second state, providing a reliable guarantee for realizing the second water outlet mode. Through the coordinated operation of the first mixing port 2a1 and the second mixing port 2a2, the moving valve plate 2 can accurately control the mixing and water outlet of hot and cold water in different states, meeting the diverse water needs of users.

[0037] It is particularly important to note that when the movable valve plate 2 is slidably switched to the first state, the second mixing port 2a2 and the second outlet port 1d are always misaligned. The rotation of the movable valve plate 2 allows the first mixing port 2a1 to rotate and cover the cold water inlet port 1a and the hot water inlet port 1b to adjust the mixing ratio of cold and hot water flowing into the mixing chamber 2a. The first mixing port 2a1 can communicate with the first outlet port 1c, and the movable valve plate 2 is constrained above the stationary valve plate 1 and can only rotate within a set angle range, thereby limiting the rotation of the movable valve plate 2 to the first... The angle of the mixing port 2a1 completely covering the hot water inlet 1b is used to prevent the first outlet 1c from being filled with hot water. When the moving valve plate 2 slides to the second state, the first mixing port 2a1 and the first outlet 1c are always misaligned. The rotation of the moving valve plate 2 can make the first mixing port 2a1 rotate to cover the cold water inlet 1a and the hot water outlet, and the second mixing port 2a2 can connect to the second outlet 1d. When the moving valve plate 2 is in the second state, it can adjust the mixing ratio of cold and hot water flowing to the mixing chamber 2a as needed during the rotation.

[0038] The specific structure and function of valve housing 3 are as follows, for reference. Figure 1 , Figure 2 and Figure 5As shown, the valve housing 3, serving as the external protection and support structure for the valve core, consists of an upper housing 31 and a valve seat 32. The upper housing 31 and valve seat 32 are connected by a detachable structure, which greatly facilitates the assembly, disassembly, and subsequent maintenance of the valve core. The detachable structure mainly includes a retaining groove 31b on the upper housing 31 and a snap fastener 32a on the valve seat 32. The snap fastener 32a fits tightly into the retaining groove 31b, achieving a stable connection between the two. Simultaneously, to further ensure the accuracy and stability of the connection, a positioning groove 31c is provided on the upper housing 31, and a corresponding positioning block 32b is provided on the valve seat 32. The positioning block 32b can be precisely embedded in the positioning groove 31c, effectively preventing misalignment or displacement of the upper housing 31 and valve seat 32 during connection. A through mounting hole 31a is formed on the upper housing 31, providing rotational space for the rotor 5 and ensuring smooth rotation of the rotor 5 within the upper housing 31. Multiple water inlets are provided through the bottom of the valve body 3, namely, cold water inlet 3a corresponding to cold water inlet 1a, hot water inlet 3b corresponding to hot water inlet 1b, first outlet 3c corresponding to first outlet 1c, and second outlet 3d corresponding to second outlet 1d. These water inlets are all located on the valve seat 32. They are important channels for water to enter and exit the valve core, ensuring the water circulation of the entire valve core system.

[0039] The specific structure and connection method of valve handle 4, rotor 5 and dial 6 are as follows: (Reference) Figure 1 , Figure 2 and Figure 5 As shown, the valve core also includes a valve handle 4, a rotor 5, and a dial 6 arranged sequentially. The valve handle 4 is hinged to the rotor 5, allowing it to swing back and forth within a certain range. When the user operates the valve handle 4 to swing, the valve handle 4 drives the dial 6 to move. Simultaneously, the dial 6 is constrained to the bottom of the rotor 5, enabling it to rotate with the rotor 5 and slide relative to it. The moving valve plate 2 is fixed to the bottom surface of the dial 6. When the dial 6 moves or rotates, the moving valve plate 2 moves synchronously, thus achieving rotation and sliding of the moving valve plate 2 relative to the stationary valve plate 1. The stationary valve plate 1 is fixed to the bottom of the inner cavity of the valve housing 3, ensuring its positional stability. The upper end of the valve handle 4 protrudes from the top of the upper housing 31, facilitating direct user operation. The user can control the valve core by swinging or rotating the valve handle 4. The lower end of the valve handle 4 is connected to the dial 6, ensuring that the movement of the valve handle 4 is accurately transmitted to the dial 6, thereby driving the moving valve plate 2 to work.

[0040] The specific structure of the limiting device 7 is as follows: (Refer to) Figure 2 , Figures 6 to 8As shown, to ensure that the rotation angle of the moving valve plate 2 is within a safe range in the sensing water outlet mode and to prevent scalding of users by the outflow of hot water, a limiting device 7 is specially set between the valve housing 3 and the rotor 5. The limiting device 7 mainly consists of a first limiting wall 7a and a second limiting wall 7b located inside the valve housing 3 and spaced apart circumferentially, and a third limiting wall 7c and a fourth limiting wall 7d formed on the side of the rotor 5. The third limiting wall 7c can fit the first limiting wall 7a, and the fourth limiting wall 7d can fit the second limiting wall 7b. When the rotor 5 rotates to the first position, that is... Figure 7 At the position shown, the first limiting wall 7a will abut against the third limiting wall 7c, preventing the rotor 5 from continuing to rotate in the forward direction; when the rotor 5 reverses to the second position, that is... Figure 8 At the position shown, the second limiting wall 7b abuts against the fourth limiting wall 7d, restricting the rotor 5 from continuing to rotate in the opposite direction. This limiting method effectively constrains the rotation range of the rotor 5, thereby limiting the rotation angle of the moving valve plate 2. This fundamentally avoids the dangerous angle at which the moving valve plate 2 rotates to completely cover the hot water inlet hole 1b at the first mixing port 2a1, ensuring user safety.

[0041] The specific working principle of the moving valve disc 2 of the valve core in the first or second state is as follows:

[0042] First state (sensor-activated water dispensing mode)

[0043] When the movable valve plate 2 slides to the first state, the second mixing port 2a2 is misaligned with the second outlet 1d, and only the first outlet 1c is open. Rotating the valve handle 4, the movable valve plate 2 can only rotate within the range of 0°-90°. At the 0° position ( Figure 9 As shown), mixing chamber 2a is not open, and the valve core is closed; at the 45° position ( Figure 10 As shown), the first mixing port 2a1 covers the cold water inlet 1a, and all cold water flows out; at the 90° position ( Figure 11 As shown, the first mixing port 2a1 simultaneously covers both the cold and hot water inlets, allowing the hot and cold water to mix in a specific ratio. The limiting device 7 prevents the rotor 5 from rotating beyond its range, and prevents the moving valve plate 2 from completely covering the hot water inlet 1b, thus avoiding accidental scalding from the outflow of hot water. After mixing in the mixing chamber 2a, the hot and cold water flow out from the first outlet 3c through the first inlet area 2a11 of the first mixing port 2a1 and the first outlet 1c.

[0044] Second state (manual water dispensing mode)

[0045] The moving valve plate 2 slides to the second state (the moving valve plate switches from the first state to the second state indirectly driven by the valve stem). At this time, the first mixing port 2a1 is misaligned with the first outlet port 1c, and only the second outlet port 1d is open. Rotating the valve handle 4 causes the moving valve plate 2 to rotate and adjust the mixing ratio. At this time, the moving valve plate 2 can only rotate within the range of 0°-90°. At the 0° position ( Figure 12 As shown), the second mixing port 2a2 covers the cold water inlet 1a, and all cold water flows out; at the 45° position ( Figure 13 As shown), the second mixing port 2a2 simultaneously covers the hot and cold water inlets, and the mixed water flows out; at the 90° position ( Figure 14 As shown), at this time, the second mixing port 2a2 can completely cover the hot water inlet 1b. Therefore, in the manual water outlet mode, all hot water can flow out. All cold water, mixed water and all hot water can flow out from the second mixing port 2a2 through the second outlet 1d and then from the second outlet 3d.
