Description

[0002] With the progress of society and the development of technology, the popularity of automation and smart home systems is increasing, which puts higher requirements on the functionality of traditional equipment such as valves.

[0003] Traditional valves usually use manual or simple mechanical methods to control water flow. This control method has many problems in flow regulation accuracy, ease of operation and durability. Among them, manual operation is often time-consuming and labor-intensive, and it is difficult to provide users with a better user experience. In the traditional mechanical valve structure, the cooperation between the electric porcelain valve and the valve core moving porcelain piece is mainly utilized, that is, the porcelain force generated by the power of the electric porcelain coil drives the valve core moving porcelain piece to move relative to the valve core fixed porcelain piece, thereby controlling the flow or flow direction of the fluid. However, on the one hand, this operation method can only realize the opening or closing of the water flow, and the form is relatively simple, and it cannot effectively control the size of the water flow. On the other hand, in the process of frequent movement of the valve core moving porcelain piece, the silicone pad arranged inside it is often worn or even stuck due to impurities in the water, thereby affecting the overall sealing effect of the electric valve.

[0027] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0028] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0029] like Figures 1 to 3 As shown, the present invention provides a multifunctional electric valve structure assembly, comprising: a housing 1 provided with an accommodating cavity 10; a valve core fixed ceramic plate 20 and a driving module 3, the valve core fixed ceramic plate 20 being installed in the accommodating cavity 10, and a water through hole 200 being opened in the valve core fixed ceramic plate 20; the driving module 3 being arranged on the housing 1, and a valve core moving ceramic plate 21 being connected to the driving module 3, the valve core moving ceramic plate 21 extending into the accommodating cavity 10 and movably pressed against the valve core fixed ceramic plate 20, and a water supply hole 210 being opened on the valve core moving ceramic plate 21; the valve core moving ceramic plate 21 can rotate relative to the valve core fixed ceramic plate 20 due to the drive of the driving module 3, so as to adjust the overlapping area between the water supply hole 210 and the water through hole 200 to control the water output.

[0030] Compared with the traditional technology that relies on the porcelain force generated by the electric porcelain coil to drive the valve core moving porcelain piece 21 relative to the valve core fixed porcelain piece 20, this embodiment has made further improvements. Specifically, Figures 1 to 3As shown, when the drive module 3 is not activated, the valve core moving porcelain disc 21 and the valve core fixed porcelain disc 20 are in a specific relative position. At this time, the water supply hole 210 on the valve core moving porcelain disc 21 and the water through hole 200 on the valve core fixed porcelain disc 20 may partially overlap, completely overlap, or not overlap, depending on the preset initial flow control requirements. When the water output needs to be adjusted, the drive module 3 will start working after receiving an electrical signal from the control system. Since the output shaft 300 of the drive module 3 is connected to the valve core moving porcelain disc 21, it will drive the valve core moving porcelain disc 21 to rotate relative to the valve core fixed porcelain disc 20. As the valve core moving porcelain disc 21 rotates, the overlapping area between the water supply hole 210 on the valve core moving porcelain disc 21 and the water through hole 200 on the valve core fixed porcelain disc 20 changes. This change directly affects the effective cross-sectional area of the water flow channel, thereby accurately controlling the water flow through the valve. It is precisely because the drive module 3 drives the rotation of the valve core movable ceramic disc 21 relative to the valve core fixed ceramic disc 20 that the water flow can be precisely controlled by adjusting the overlapping area to meet the flow requirements in different scenarios. It also effectively avoids the wear and even jamming of the silicone pad caused by impurities in the water in traditional structures, greatly ensuring the service life and overall efficiency of the electric valve structure. Preferably, the valve core fixed ceramic disc 20 and the valve core movable ceramic disc 21 in this embodiment are both made of wear-resistant, high-temperature-resistant, and odor-free ceramic materials.

[0031] The drive module 3 includes a drive motor 30 and a connecting shaft 31. A PCB board 11 is provided on the casing 1. The drive motor 30 is connected to the PCB board 11 and is used to control the rotation of the drive motor 30 through a pulse signal emitted by the PCB board 11; one end of the connecting shaft 31 is connected to the output shaft 300 of the drive motor 30, and the other end is connected to the valve core movable porcelain piece 21.

[0032] Further, if Figure 2 and Figure 3 As shown, it should be noted that the drive motor 30 in this embodiment is preferably a stepper motor. Of course, other rotatable devices can also be used instead. The drive motor 30 can operate after receiving a pulse signal from the PCB board 11. Since it adopts a pulse control method, the drive motor 30 has the ability to start and stop quickly and accurately position (i.e., accurately control the rotation angle and speed of the motor), and exhibits excellent dynamic response characteristics under working conditions that require frequent adjustment. When the drive motor 30 rotates, the connecting shaft 31 connected to the output shaft 300 of the drive motor 30 can drive the valve core moving porcelain piece 21 to rotate synchronously, thereby changing the relative position between the valve core moving porcelain piece 21 and the valve core fixed porcelain piece 20 (i.e., changing the position of the water supply hole 210 relative to the water through hole 200), so that the overlapping area between the water supply hole 210 and the water through hole 200 changes. This structure realizes a high-precision and high-efficiency flow regulation function through the coordinated control of the drive motor 30 and the PCB board 11.

[0033] Preferably, if Figure 1 As shown, in this embodiment, a column 18 can also be installed on the housing 1, and an assembly hole 180 is opened in the mounting column 18. The above-mentioned PCB board 11 and the housing of the drive motor 30 can pass through the assembly hole 180 through screws, bolts and other connecting parts to achieve rapid installation and disassembly between the PCB board 11, the drive motor 30 and the housing 1, providing great convenience for subsequent maintenance and replacement.

[0034] A zero position groove 310 is further provided at the end of the connecting shaft 31 away from the valve core movable porcelain piece 21 , and a sensor 110 is mounted on the PCB board 11 . The sensor 110 is used to detect the rotation and reset of the driving motor 30 .

[0035] More preferably, Figure 1 and Figure 3 As shown, a specially designed sensor 110 (which may be an optical sensor 110, a Hall effect sensor 110, etc.) is installed on the PCB board 11 in this embodiment to detect the existence of the zero position slot 310; when the connecting shaft 31 rotates past the sensor 110, the sensor 110 can identify the zero position slot 310 and feed this signal back to the PCB board 11. Once the zero position is detected, the PCB board 11 records the current state as a reference point and adjusts the position of the drive motor 30 accordingly to achieve the required initial set value. Specifically, when the drive motor 30 drives the valve core moving porcelain piece 21 to rotate relative to the valve core fixed porcelain piece 20, it is bound to be related to the change of the overlapping area of the water supply hole 210 and the water hole 200, thereby affecting the overall water flow; and by setting the zero position slot 310 and using the sensor 110 for precise detection, it can be ensured that the reference point can be accurately found each time it is started, avoiding the problem of inaccurate positioning caused by cumulative errors. That is to say, when the output shaft 300 of the drive motor 30 moves along Figure 1 When the housing 1 rotates 90 degrees in the clockwise direction in the radial direction, the zero position slot 310 on the connecting shaft 31 will inevitably rotate 90 degrees synchronously, so that when the driving motor 30 is reset (i.e., along the Figure 1 When the housing 1 rotates radially counterclockwise), if the output shaft 300 of the drive motor 30 has not rotated to the full position (for example, it has only rotated 85 degrees during the reset process), it can be quickly identified by the sensor 110, effectively avoiding the accumulation of errors during the reset and resulting in precise control of the overlapping area of the water supply hole 210 and the water through hole 200.

[0036] The end of the connecting shaft 31 is symmetrically provided with extension blocks 311 along its radial direction. Each extension block 311 is provided with a locking groove 311a. The side wall of the valve core movable porcelain piece 21 is provided with a locking block 211, and the locking block 211 is locked in the locking groove 311a.

[0037] More preferably, Figure 3As shown, this embodiment is aimed at the installation between the connecting shaft 31 and the valve core movable porcelain disc 21, and mainly relies on the snap-fit block 211 to be firmly embedded in the snap-fit groove 311a (similar to the interference fit between the hole shaft), ensuring that the connection between the two is more stable and reliable, avoiding the risk of operational errors or equipment damage caused by looseness, so that when the connecting shaft 31 rotates, it can directly transmit the torque to the valve core movable porcelain disc 21, causing the valve core movable porcelain disc 21 to rotate synchronously. This structural design simplifies the assembly steps between the valve core movable porcelain disc 21 and the connecting shaft 31, reduces the complex calibration process, improves work efficiency, and reduces the difficulty of maintenance; at the same time, the stable connection method reduces the wear between parts, helps to extend the service life of the entire valve assembly, and reduces the long-term use cost. It should be noted that the assembly method between the valve core movable porcelain disc 21 and the connecting shaft 31 is not limited to the case in this embodiment, and other assembly methods such as screws or bolts can also be used.

[0038] A connecting sleeve 12 is also provided in the accommodating cavity 10. An opening 120 is formed at one end of the connecting sleeve 12, and a guide portion 121 is formed at the other end. The valve core fixed porcelain piece 20 is sealed against the inner wall of the connecting sleeve 12, so that the water hole 200 is aligned with the opening 120 and connected to each other; the connecting shaft 31 is movably inserted into the guide portion 121 and connected to the valve core movable porcelain piece 21.

[0039] More preferably, Figure 2 and Figure 3 As shown, the valve core fixed ceramic disc 20 and the valve core movable ceramic disc 21 in this embodiment are both disposed within the connecting sleeve 12. During assembly, the valve core fixed ceramic disc 20 forms a seal with the inner wall of the connecting sleeve 12 through its radial sidewalls, preventing water from leaking from locations outside the water through hole 200. At the same time, the water through hole 200 on the valve core fixed ceramic disc 20 and the opening 120 of the connecting sleeve 12 remain completely aligned (i.e., on the same axial centerline), ensuring a smooth water flow channel. In addition, this embodiment utilizes a guide portion 121 formed on the connecting sleeve 12 to guide the installation of the connecting shaft 31 and limit radial displacement or shaking, ensuring that the connecting shaft 31 remains stable during high-speed or frequently changing direction movements, avoiding wear or jamming due to deflection. While improving the fit consistency between the valve core movable ceramic disc 21 and the valve core fixed ceramic disc 20, it also ensures the linearity and response speed of flow control.

[0040] The casing 1 is also provided with a pipe port 13 and a pipe port 2 14. The outer wall of the connecting sleeve 12 is provided with a plurality of water inlets 122 distributed in a circular shape and at equal intervals. The water inlets 122 are connected to the pipe port 13. The water inlets 122 can be connected to the pipe port 2 14 when the water supply hole 210 and the water hole 200 have an overlapping area.

[0041] Further, if Figures 1 to 3As shown, when water flows into the accommodating chamber 10 from the nozzle 13 on the housing 1, it will first encounter multiple water inlets 122 on the outer wall of the connecting sleeve 12. By setting the water inlets 122 on the outer wall of the connecting sleeve 12 in an annular and equidistant manner, it can ensure that the incoming water flow can be evenly distributed in the connecting sleeve 12, avoiding the problems of excessive local pressure or uneven water flow, which helps to improve the overall performance and service life of the valve. When the water flow is guided into the interior of the connecting sleeve 12, and in the process begins to flow to the overlapping area between the valve core fixed porcelain piece 20 and the valve core movable porcelain piece 21 (see Figure 2 The direction of water flow under the overlapping area of the arrow shown) is finally gathered at the pipe mouth 2 14 and flows out. It should be noted that as long as the water supply hole 210 on the valve core moving porcelain piece 21 and the water through hole 200 on the valve core fixed porcelain piece 20 have an overlapping part, the water flow can pass smoothly (no need to be in a fully open state), and the direction of water flow can flow from pipe mouth 1 to pipe mouth 2, and conversely, it can also flow from pipe mouth 2 to pipe mouth 1. Combined with the design of the valve core moving porcelain piece 21 and the valve core fixed porcelain piece 20, the relative rotation between the two is used to adjust the effective cross-sectional area of the water flow channel, thereby achieving precise control of the flow rate; at the same time, the pipe mouth 1 13, the pipe mouth 2 14, the water supply hole 210 and the water through hole 200 are rationally arranged in a compact space, which not only reduces the complexity of the pipeline, but also reduces the manufacturing cost, while improving the reliability and maintenance convenience of the electric valve.

[0042] More preferably, Figure 2 As shown, in this embodiment, there is at least one pipe orifice 14, that is, the number of pipe orifices 13 can be one or more. When the number of pipe orifices 13 is one, as the above-mentioned drive motor 30 drives the valve core moving porcelain piece 21 to rotate, when the water supply hole 210 and the water through hole 200 have an overlapping area, the pipe orifice 13 and the pipe orifice 2 14 can be connected to each other to supply water along the desired direction; and when there are multiple pipe orifices 14 (the number is two or more), at this time, the electric valve has one pipe orifice 13 corresponding to multiple pipe orifices 2 14. Under this structure, the water flow can be The water flows from the pipe mouth 13 through the upper water inlet to the connecting sleeve 12. When the driving motor 30 drives the valve core moving magnetic piece 21 to adjust the overlapping area of the water supply hole 210 and the water hole 200, the corresponding pipe mouth 2 14 can also be selected (that is, one or more of the multiple pipe mouths 2 14 can be selected, that is, according to different usage requirements, the diameter size of the water supply hole 210 and the pipe mouth 2 14 can be set or the spacing distance between multiple pipe mouths 2 14 can be set, so that the water supply hole 210 can be connected to one or more pipe mouths 2 14 at the same time) to ensure that the water flow can meet different usage requirements. In addition, the water flow direction in this embodiment is not limited to Figure 2 In the direction of the arrow shown, that is, in the case where one nozzle 13 corresponds to multiple nozzles 2 14, multiple same or different water flows can also flow from Figure 2The multiple pipe openings 2 14 shown flow to the overlapping area of the water supply hole 210 and the water through hole 200, and finally mix in the connecting sleeve 12 and flow to the pipe opening 13 through the upper water inlet. Therefore, this structure not only allows users to flexibly select the direction and flow rate of water flow according to actual needs and adapt to different usage scenarios, but also supports the mixing of multiple water sources, helps to obtain ideal water quality and temperature, and meet a wider range of usage needs.

[0043] This embodiment further includes a limit block 15 movably sleeved on the guide portion 121 . The limit block 15 movably presses against the step of the connecting sleeve 12 and engages with the inner wall thread of the accommodating cavity 10 .

[0044] More preferably, Figure 2 As shown, during the assembly of the electric valve, after the valve core fixed ceramic piece 20 and the connecting sleeve 12 are initially fixed, the limit block 15 can be inserted from one end of the guide portion 121 and slid tightly to the side wall position of the step at the connecting sleeve 12 (refer to Figure 2 ), in order to realize the positioning of the limit block 15 itself, the limit block 15 of this embodiment and the inner wall of the accommodating cavity 10 are screw-locked (internal and external threads match), which effectively prevents the axial displacement or loosening of the connecting sleeve 12 and its internal valve core fixing ceramic piece 20 during use. In addition, the thread matching structure simplifies the assembly process, facilitates the later maintenance, replacement of parts or cleaning of the connecting sleeve 12, and helps to extend the service life of the electric valve structure.

[0045] An inner sealing ring 123 and an outer sealing ring 124 are provided between the connecting sleeve 12 and the casing 1. The inner sealing ring 123 is respectively located at the periphery where the opening 120 is connected to the warm water pipe port 140 and at the periphery where the opening 120 is connected to the heating pipe port 141; the outer sealing ring 124 surrounds the two inner sealing rings 123 inside it.

[0046] More preferably, Figure 2 and Figure 3 As shown, this embodiment greatly improves the sealing performance of the electric valve structure by providing two inner and outer sealing rings. By directly applying the inner sealing ring 123 to the key water channel interface, it ensures that the connection between the heating pipe port 141 and the warm water pipe port 140 and the opening 120 will not accidentally leak. The outer sealing ring 124 provides an additional layer of protection, ensuring that water does not directly leak into the water outlet 14 through the gap between the connecting sleeve 12 and the accommodating cavity 10, thereby enhancing the overall sealing reliability. Therefore, a good sealing design reduces the risk of corrosion caused by water leakage and also reduces maintenance frequency, which helps to extend the overall service life of the valve assembly.

[0047] More preferably, Figure 2As shown, in this embodiment, a first sealing ring 16 is provided between the inner wall of the guide portion 121 and the connecting shaft 31, and a second sealing ring 17 is provided between the outer wall of the connecting sleeve 12 and the inner wall of the accommodating chamber 10 (of course, this structure can also adopt the double sealing structure of the above-mentioned inner / outer sealing rings 124, and the valve core fixed ceramic piece 20 and the inner wall of the connecting sleeve 12 can also use sealing rings to achieve sealing and tightness, which will not be described in detail here). Similarly, by providing the first / second sealing ring 17 at key positions, water leakage can be effectively prevented (that is, the sealing between the guide portion 121 and the connecting shaft 31, and between the connecting sleeve 12 and the inner wall of the accommodating chamber 10 is guaranteed, ensuring that the water flows out stably in the specified direction). Good sealing helps to maintain a stable internal pressure and fluid flow path, reduce energy loss, and improve energy utilization efficiency.
