[0068] The utility model will be described in more detail below with reference to a preferred embodiment and in connection with the drawings.

[0069] With reference to Figures 1-8As shown, the embodiment provides a water electromagnetic valve 100, which comprises a valve body 110, and further comprises an adjusting assembly arranged in the valve body 110. The valve body 110 is internally formed with a water flow channel. The adjusting assembly comprises a flow divider 120, a valve core 130 and a flow stabilizer 140. The flow divider 120 is arranged in the water flow channel to separate the water flow channel into a main flow channel and a secondary flow channel. The flow stabilizer 140 is arranged in a cavity of the flow divider 120 and located in the main flow channel. The valve core 130 is arranged in the valve body 110 and can move relative to the valve body 110. The valve core 130 is close to or away from the secondary flow channel to close or open the secondary flow channel.

[0070] In the embodiment, the adjusting assembly can separate the water flow channel into the main flow channel and the secondary flow channel, so that the water flow is clearly separated in the valve body 110, which can be used to control the direction and flow of the water flow. The flow stabilizer 140 can help stabilize the water flow in the main flow channel. The valve core 130 moves in the valve body 110, so that it can flexibly open or close the secondary flow channel, thereby flexibly adjusting the rate and flow of the water flow, and achieving better water flow distribution. When the secondary flow channel is closed, the water flow flows from the main flow channel and realizes the flow stabilization effect through the action of the flow stabilizer 140. When the secondary flow channel is opened, the water flow can also flow from the secondary flow channel, realizing the effect of increasing water pressure and water flow, and realizing the flexible switching between the flow stabilization state and the pressure increasing state.

[0071] As shown, Figures 2-8 The flow divider 120 comprises an extension part 121, a first end wall part 122 and a side wall part 123. Along the axial direction of the flow divider 120, the extension part 121, the first end wall part 122 and the side wall part 123 are arranged in sequence. The side wall part 123 surrounds the circumference of the first end wall part 122 and is connected with one end of the first end wall part 122. The extension part 121 is connected with the other end of the first end wall part 122, and the radial dimension of the extension part 121 is smaller than that of the first end wall part 122. The flow divider 120 further has a first through hole 125 and a second through hole 126. The first through hole 125 extends from the end of the extension part 121 to the first end wall part 122, does not penetrate through the first end wall part 122, but extends to the side wall of the extension part 121 and penetrates through, so as to communicate the outside space of the extension part 121 and the side wall part 123, and serve as part of the secondary flow channel. The second through hole 126 penetrates through the first end wall part 122 to communicate the internal space of the side wall part 123, and serve as part of the main flow channel.

[0072] In the present embodiment, by setting the first through hole 125 and the second through hole 126 in the flow distributor 120, the water flow can follow a predetermined path, the first through hole 125 extends from the end of the extension 121 to the first end wall 122, but does not penetrate through the first end wall 122, but instead extends to the outside of the side wall 123 and penetrates through, which design makes the water flow can bypass the flow distributor 120, rather than directly through. The first through hole 125 and the second through hole 126 correspond to the secondary flow passage and the main flow passage respectively, which is more convenient to adjust the water flow path, accurately control whether the water flow flows into the secondary flow passage, to achieve the effect of pressure increase or flow stabilization. The arrangement of the first end wall 122, the side wall 123 and the extension 121 along the axial and radial directions of the flow distributor 120 not only provides more water flow paths, but also makes the size of the flow distributor 120 smaller, so that the overall structure of the water solenoid valve 100 can be more compact, providing better space utilization efficiency, and possibly reducing the overall structure size.

[0073] As shown in Figures 2-8 , the flow distributor 120 further comprises a second end wall 124, the second end wall 124 is located at both ends of the first end wall 122 with the side wall 123, the extension 121 penetrates through the second end wall 124, the second through hole 126 extends from the second end wall 124 to the first end wall 122 and penetrates through the first end wall 122. Due to the addition of the second end wall 124 to the flow distributor 120, bidirectional control of water flow is achieved, and the water flow path to the main flow passage and the secondary flow passage is refined, the second through hole 126 extends from the second end wall 124 to the first end wall 122 and penetrates through the first end wall 122, which means that the water flow can flow along the gap between the outside of the side wall 123 after passing through the second end wall 124 to the first end wall 122, forming a part of the continuous secondary flow passage. The extension 121 is arranged in a manner that makes the parts cooperate more closely.

[0074] As shown in Figure 4 and Figure 8 , the water solenoid valve 100 further comprises a plurality of sealing members 150, the outer surface of the second end wall 124 is provided with a first groove 1241 for accommodating the sealing member 150, and the part of the extension 121 outside the second end wall 124 is provided with a second groove 1211 for accommodating the sealing member 150. By accommodating the sealing member 150 through the groove, the leakage of water flow can be effectively prevented, the design of the first groove 1241 and the second groove 1211 limits the sealing member 150 in the appropriate position to provide reliable sealing, enhances the structural reliability, reduces the maintenance cost and is more convenient to install and replace.

[0075] As shown in Figure 8As shown, the first end wall portion 122 is convex to the extension portion 121 and has a conical outer profile. The conical outer profile of the first end wall portion 122 can effectively reduce the resistance of water flow. When water flows through this portion, the conical design can guide the water flow smoothly, thereby reducing turbulence and water flow resistance. This helps to improve the efficiency of the entire water electromagnetic valve 100. The outer profile of the conical structure can guide the direction of water flow, and the fluid naturally flows along the path of the conical profile, which makes the water flow direction more controllable. This feature is very useful in applications that require a specific water flow direction. The convex conical structure can be more easily aligned with other components, ensuring correct installation and positioning.

[0076] As shown in FIG. 1, the water electromagnetic valve 100 includes a valve body 110, a flow regulator 120, and a regulating assembly 130. Figures 5-8 As shown, the flow stabilizer 140 is arranged in the cavity of the side wall portion 123, the inner surface of the side wall portion 123 is provided with a radial protrusion 1231, the position of the radial protrusion 1231 corresponds to the position of the second through hole 126, and the outer surface of the side wall portion 123 is provided with a rib 1230 extending in the axial direction of the flow regulator 120. The radial protrusion 1231 can be connected with the flow stabilizer 140 to limit the position of the flow stabilizer 140 in the side wall portion 123, and the flow stabilizer 140 can work stably and continuously without being affected by water flow impact; the outer surface of the side wall portion 123 is provided with the rib 1230 extending in the axial direction, which can provide additional structural support to increase the strength and durability of the flow regulator 120, and also can realize a stable gap space between the side wall portion 123 and the inner wall of the valve body 110 by the abutment between the rib 1230 and the inner wall of the valve body 110 to form part of the secondary flow passage, so that the water flow can pass smoothly, and the size of the rib 1230 can be controlled to adjust the water flow rate per unit time of the secondary flow passage to adapt to more scenarios.

[0077] As shown in FIG. 1, the water electromagnetic valve 100 includes a valve body 110, a flow regulator 120, and a regulating assembly 130. Figures 4-8 As shown, the regulating assembly further includes a gland 160 arranged at the water outlet of the water flow passage and abutting against the bottom of the side wall portion 123, the gland 160 is provided with a main through hole 1601, the main through hole 1601 communicates with the main flow passage; the gland 160 is further provided with a plurality of secondary through holes 1602, the plurality of secondary through holes 1602 respectively communicate with the secondary flow passage and the water outlet, the secondary through holes 1602 are arranged in a circumferential direction of the gland 160 and penetrate the side wall of the gland 160.

[0078] The main through hole 1601 on the cover 160 and the secondary through holes 1602 provide the ability to shunt, the main through hole 1601 is connected with the main flow channel, so that the main water flow is unobstructed, and the plurality of secondary through holes 1602 are respectively connected with the secondary flow channels, to provide a path for the secondary water flow. Since the secondary through holes 1602 on the cover 160 are circumferentially spaced, this design allows the water flow to be changed by adjusting the opening of the secondary through holes 1602; the water flow of the main flow channel and the secondary flow channel can be collected after passing through the cover 160; the cover 160 abuts the bottom of the side wall portion 123, providing additional support.

[0079] The valve body 110 in the embodiment also includes a protruding portion inside the inner wall of the valve body 110, one end of which is towards the valve core 130, and the other end is sleeved with the extension portion 121. The adjusting assembly also includes a diaphragm 170, which is covered on the end of the protruding portion towards the valve core 130; the valve core 130 moves towards the diaphragm 170 along the radial direction of the water flow channel to abut the diaphragm 170 to block the secondary flow channel; the valve core 130 moves away from the diaphragm 170 along the radial direction of the water flow channel by a preset distance to open the secondary flow channel.

[0080] The valve core 130 moves along the radial direction of the water flow channel, and blocks the secondary flow channel by contacting the diaphragm 170, which can achieve precise water flow control, so that the water electromagnetic valve 100 can flexibly open and close the secondary flow channel as needed, and realize flexible switching between the effects of pressure boosting and flow stabilization. The contact between the diaphragm 170 and the valve core 130 can effectively block the secondary flow channel and prevent water leakage. When the valve core 130 does not contact the diaphragm 170, the water flow can flow through the diaphragm 170 and then enter the secondary flow channel. The diaphragm 170, as an independent component, can be replaced, reducing the overall maintenance cost.

[0081] As shown in Figures 1-4 The water electromagnetic valve 100 also includes a turbine Hall assembly 1901 and a temperature sensor 1902. The valve body 110 includes a first portion 1101 and a second portion 1102. The radial direction of the first portion 1101 and the radial direction of the second portion 1102 form an angle, and the second portion 1102 is used to connect with the water inlet pipeline, and the first portion 1101 is used to connect with the water outlet pipeline. The adjusting assembly is arranged in the first portion 1101, and the turbine Hall assembly 1901 and the temperature sensor 1902 are arranged in the second portion 1102.

[0082] The turbine Hall component 1901 is arranged in the second part 1102 connected with the water inlet pipeline, and the frequency of the turbine rotation is perceived through the Hall effect, so as to realize the accurate measurement of the water flow. This technology can provide high-precision flow data, which helps to control the working state of the water electromagnetic valve 100. The temperature sensor 1902 is arranged in the second part 1102, which can monitor the temperature of the water inlet, thereby preventing failure caused by excessively high or low temperature. The angle between the first part 1101 and the second part 1102 of the valve body 110 is designed to allow the water electromagnetic valve 100 to adapt to different installation environments. The angle design provides flexibility for installation in narrow spaces or special pipeline layout. The adjusting component is arranged in the first part 1101, and the turbine Hall component 1901 and the temperature sensor 1902 are arranged in the second part 1102. This separation design helps to avoid interference and improve the performance and accuracy of the components.

[0083] The embodiment further provides a water heater based on the water electromagnetic valve 100 described above, which includes the water electromagnetic valve 100 described above. When the water electromagnetic valve 100 provided with the adjusting component is applied to the water heater, the user can flexibly switch between the steady flow state and the pressure boosting state when using the water heater, thereby improving the user experience. The water electromagnetic valve 100 using the turbine Hall component 1901 can realize accurate water flow control in the water heater and perform real-time temperature monitoring, thereby improving the user experience.

[0084] Specifically, when the user wants to realize the steady flow effect when using the water heater, the valve core 130 of the water electromagnetic valve 100 is controlled to move towards the diaphragm 170 to block the hole above the diaphragm 170, which is arranged corresponding to the water inlet on the upper end of the extension part 121. At this time, the water flow flows from the second part 1102 into the first part 1101, and the water flow passing through the diaphragm 170 cannot flow into the valve body 110 from the upper end of the diaphragm 170. The water flow enters the flow channel inside the side wall part 123 through the second through hole 126. Since the steady flow piece 140 is arranged in the side wall part 123, it can stabilize the water flow. At this time, only the main flow channel water flows, as shown in the middle main flow channel path E. Figure 4

[0085] ​When the user needs to boost the water flow when using, the valve core 130 of the water electromagnetic valve 100 is controlled to move away from the diaphragm 170, at this time the hole on the diaphragm 170 is opened to enable the upper space to communicate with the space below the valve body 110, at this time the water flow from the second part 1102 can pass through the diaphragm 170, and then flow into the flow channel above the extension 121 from the hole on the diaphragm 170, and then flow into the extension 121, and then flow into the space outside the side wall part 123 from the flow channel formed between the extension 121 and the second end wall part 124, which is the water flow channel formed by the side wall part 123 and the inner surface of the valve body 110, and then the water flow converges in the middle part of the cover 160 from the secondary through hole 1602 arranged on the cover side, and then flows out, at this time the water flow of the secondary channel does not pass through the action of the flow stabilizing piece 140, such as Figure 5 The secondary flow channel path F is shown, and at the same time, the main flow channel water flow is normally circulated as described above, and the overall pressure boosting effect is achieved. The above process is used to meet the user's flexible and convenient switching between the pressure boosting and the flow stabilizing state.
