Obviously, the described embodiments are some of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only to represent selected embodiments of the present application.
[0029] Embodiment
[0030] In combination with Figures 1 to 7 The present embodiment provides a novel electronic valve core, comprising a valve body 1, a mounting seat 2, and a control member 3. The valve body 1 has a cold water inlet 11, a hot water inlet 12, a mixed water cavity, and a mixed water outlet 13. The mounting seat 2 is correspondingly arranged on the valve body 1; the control member 3 is arranged on the mounting seat 2 and correspondingly adjusts the water temperature in the mixed water cavity under the control of a temperature adjustment instruction. The control member 3 comprises a linear motor 31 and a movable member 32 cooperating with the linear motor 31. The movable member 32 is movably arranged in the mixed water cavity, and the linear motor 31 is arranged in sealed connection with the movable member 32 to drive the movable member 32 to change position along the axial direction to correspondingly adjust the water inflow of the two inlets.
[0031] The novel electronic valve core described above can accurately adjust the water inflow of cold water and hot water through the linkage combination of the linear motor 31 and the movable member 32, thereby accurately controlling the water temperature in the mixed water cavity. Moreover, due to the linear motion characteristics of the linear motor 31, the movable member 32 can move quickly, thereby realizing quick response to temperature control requirements and significantly improving the response speed of water temperature adjustment. Compared with traditional mechanical adjustment devices, the combination of the linear motor 31 and the movable member 32 can realize accurate control under a more simplified structure, reduces the complexity of mechanical structure, and improves reliability and maintenance convenience.
[0032] In particular, by sealingly connecting the linear motor 31 and the movable member 32, leakage of fluids such as cold water and hot water during operation can be effectively prevented. Water leakage not only affects temperature control accuracy, but also damages the device and even affects user safety, so that the sealing arrangement of the two can ensure that the water flow inside the valve body 1 only flows in the set channel, thereby improving the reliability and safety of the system.
[0033] It is necessary to mention that the linear motor 31 is usually one of the core components of the electronic control valve, and the sealed design can prevent moisture or humidity from entering the linear motor 31 and the related electrical components, thereby avoiding short circuit, corrosion or damage of the motor and the control system, prolonging the service life of the equipment, and improving the stability and durability of the system. In addition, the sealed connection can ensure the accurate position and movement of the movable part 32, prevent temperature fluctuations caused by water leakage or system malfunction, and improve the sealing performance to help the movable part 32 adjust the water temperature without being disturbed by external factors, thereby more accurately adjusting the water temperature and improving the constant temperature effect.
[0034] In this embodiment, the connecting shaft 311 of the linear motor 31 is sealingly inserted into the movable part 32, the movable part 32 can move relative to the mounting seat 2 and the mixed water cavity, and the first sealing member 4 is arranged between the movable part 32 and the mounting seat 2, and the second sealing member 5 is arranged between the movable part 32 and the mixed water cavity. Specifically, a sealing ring is arranged between the connecting shaft 311 and the movable part 32, and the connecting shaft 311 is tightly inserted into the movable part 32 through the sealing ring.
[0035] Further, the first sealing member 4 between the movable part 32 and the mounting seat 2 can effectively prevent water flow from leaking from the inside of the valve body 1 to the outside of the mounting seat 2, thereby avoiding short circuit, corrosion or other safety hazards caused by water leakage in the electrical part. The second sealing member 5 between the movable part 32 and the mixed water cavity can ensure that the water flow only flows in the mixed water cavity, thereby preventing the water flow from leaking through an inappropriate path, further enhancing the sealing performance of the equipment, and avoiding damage to other parts of the equipment by the water flow.
[0036] Preferably, the first sealing member 4 is configured as at least one sealing ring, and the second sealing member 5 is configured as at least two sealing rings. The first sealing member 4 is sleeved on the upper end side of the movable part 32, and the second sealing member 5 is sleeved on the lower end side of the movable part 32. Therefore, through multiple sets of sealing connections, the mounting seat 2 and the movable part 32, and the movable part 32 and the valve body 1 always maintain good sealing performance.
[0037] In this embodiment, the cold water inlet 11 is located on the upper side, the hot water inlet 12 is located on the lower side, and the movable part 32 moves between the cold water inlet 11 and the hot water inlet 12. When the movable part 32 is controlled by the linear motor 31 to move upward, the water inflow of the hot water inlet 12 is greater than that of the cold water inlet 11, and at this time, the temperature of the mixed water is adjusted to be higher. When the movable part 32 is controlled by the linear motor 31 to move downward, the water inflow of the hot water inlet 12 is less than that of the cold water inlet 11, and at this time, the temperature of the mixed water is adjusted to be lower, thereby achieving temperature control.
[0038] As Figures 3 to 5As shown, in the present embodiment, the movable element 32 is provided with a water passage 323, which is used to at least communicate the cold water inlet 11 and the mixed water cavity. Each water inlet can be communicated with the mixed water cavity in a manner that the water inlet opening degree can be adjusted by the movable element 32, and the mixed water cavity is directly connected with the mixed water outlet 13. In this way, the cold water of the cold water inlet 11 enters the mixed water cavity through the water passage 323, and the hot water of the hot water inlet 12 can directly enter the mixed water cavity or enter the mixed water cavity through the water passage 323, so that the two water flows are mixed and adjusted in temperature.
[0039] Further, the movable element 32 includes an upper boss part 321 and a lower body part 322. The upper boss part 321 is movably inserted and fitted with the mounting seat 2, and separates the linear motor 31 and the mixed water cavity by sleeving the first sealing element 4. The lower body part 322 is movably inserted and fitted with the mixed water cavity, and separates the cold water inlet 11 and the hot water inlet 12 by sleeving the second sealing element 5, and only allows the two water inlets to be communicated with the mixed water cavity along the water passage 323.
[0040] It should be understood that the linear motor 31 drives the movable element 32 to move upwards, so that the lower body part 322 can gradually block the cold water inlet 11 to adjust the cold water opening degree. The linear motor 31 drives the movable element 32 to move downwards, so that the lower body part 322 can gradually block the hot water inlet 12 to adjust the hot water opening degree. Through the driving of the linear motor 31, the movable element 32 can move upwards or downwards, thereby controlling the blocking degree of the lower body part 322 to the cold and hot water inlets. When the movable element 32 moves upwards, the cold water inlet 11 is gradually blocked, and the cold water flow is reduced. When the movable element 32 moves downwards, the hot water inlet 12 is gradually blocked, and the hot water flow is reduced, thereby realizing fine adjustment of the cold and hot water inlet flow. Through the more smooth and accurate flow adjustment manner, the problem of inaccurate adjustment or slow response of the traditional knob or other mechanical control mode is avoided.
[0041] As Figure 7As shown, in the preferred embodiment, the movable element 32 is composed of a cold water drain tray 32A and a hot water drain tray 32B which are detachably connected. The cold water drain tray 32A is used to communicate with the cold water inlet 11, and the hot water drain tray 32B is used to communicate with the hot water inlet 12, and the opening size of each inlet is adjusted by the up and down displacement of the movable element 32. In order to avoid the risk of breaking the entire part due to the constant cold and hot impact when the upper end of the movable element 32 contacts cold water and the lower end contacts hot water, and to improve the service life of the product and make the product safer and more reliable, the movable element 32 is provided as a hot water drain tray 32B and a cold water drain tray 32A which are detachably connected and can be made of different materials to slow down the shortening of the product life, prevent the deformation and breaking of the movable element 32 after frequent cold and hot alternation, make the product more stable, safe and reliable, and prolong the service life of the product.
[0042] In the embodiment, the mounting seat 2 is threadedly connected to the upper end face of the valve body 1 and is sealingly connected to each other. The thread connection and sealing arrangement ensure the tight connection between the mounting seat 2 and the valve body 1, which can effectively prevent water leakage. Whether in the process of cold water or hot water flowing or in the process of long-time working of the system, the thread connection and sealing structure can maintain the airtightness between the valve body 1 and the mounting seat 2, avoiding water penetration or leakage.
[0043] In the embodiment, the lower end of the movable element 32 abuts against a spring element 6 which is always in a compressed state to provide a tendency of upward resetting of the movable element 32. The spring element 6 is in a compressed state below the movable element 32 and always applies an upward elastic force to the movable element 32 to ensure that the movable element 32 can quickly return to the initial position. When the linear motor 31 drives the movable element 32 to move downward, the compression of the spring is released to help the movable element 32 to maintain the correct position. When the motor stops driving, the resetting force of the spring automatically pushes the movable element 32 upward to return to the original position. Thus, the resetting mechanism ensures that the action of the movable element 32 is more stable and reliable, avoiding the problems of valve jamming or failure to automatically recover due to the stop of the motor or interruption of the current.
[0044] The preferred embodiments of the utility model are described above, and the protection scope of the utility model is not limited to the above-mentioned embodiments. Any technical solution falling within the concept of the utility model belongs to the protection scope of the utility model.
