[0025] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] like Figure 1-Figure 7 As shown, an electric water heater with a steady-state valve structure is provided, including a body 1, a steady-state valve 15 is provided on the body 1, a connecting member 16 is provided on one end of the steady-state valve 15, a water inlet 1601 and a water outlet 1602 are provided on the connecting member 16, and a drain 1501 is provided on the steady-state valve 15. The steady-state valve 15 has a first state and a second state. When the steady-state valve 15 is in the first state, the water inlet 1601 is connected to the water outlet 1602; when the steady-state valve 15 is in the second state, the water outlet 1602 is connected to the drain 1501.

[0027] Specifically, when the water channel is switched, the steady-state valve 15 can directly guide the residual water in the pipeline to the wastewater box 17 for centralized management, avoiding direct discharge of residual water and reducing the risk of water channel pollution; when the steady-state valve 15 is in the first state, the water inlet 1601 is connected to the water outlet 1602, and the water flows directly into the pipeline used by the user, ensuring that the fresh water source provided is not contaminated by residual water and meets food-grade safety standards; when the steady-state valve 15 is switched to the second state, the water outlet 1602 is connected to the drain 1501. At this time, the water flows into the steady-state valve from the water outlet 1602 and is discharged into the wastewater box 17 through the drain 1501 for centralized treatment; it solves the food-grade safety problems in the prior art, ensures that the supply of fresh water can be carried out in a completely independent water channel, avoids cross-contamination of fresh water contacting the valve core, and further improves the hygiene standards of the water dispenser.

[0028] Further, if Figure 4 and Figure 5 As shown, the water inlet 1601 is horizontally arranged on the connecting member 16, and the water outlet 1602 is vertically arranged on the connecting member 16. The water inlet 1601 and the water outlet 1602 are L-shaped on the connecting member 16.

[0029] Specifically, the L-shaped setting allows water to flow in along the horizontal water inlet 1601 when entering the device, and then flow out through the vertical water outlet 1602. The direction of the water flow changes from horizontal to vertical, and can flow in the direction of gravity. The vertically set water outlet 1602 can ensure a smooth drainage process.

[0030] Further, if Figure 5-Figure 7 As shown, the steady-state valve 15 includes a drive assembly 1502, a valve core assembly 1503 and a valve cover 1504. The valve cover 1504 is arranged on one end of the drive assembly 1502. The valve core assembly 1503 is connected to the drive assembly 1502. The valve core assembly 1503 can move on the valve cover 1504 through the drive assembly 1502.

[0031] Specifically, the drive assembly 1502 can accurately control the movement of the valve core assembly 1503, thereby realizing precise switching of the water path; the valve stem 15031 is connected to the drive assembly 1502 and serves as a transmission mechanism, responsible for converting the movement of the drive assembly 1502 into the linear movement of the blocking member 15032, so that it can drive the blocking member 15032 to move on the valve cover 1504.

[0032] Further, if Figure 5-Figure 7 As shown, the drain outlet 1501 is located on the valve cover 1504, and a connecting structure is provided between the valve cover 1504 and the connecting member 16. The connecting structure includes a recess 15041 provided on the valve cover 1504 and a connecting column 1603 provided on the connecting member 16. The connecting column 1603 is inserted into the recess 15041 to realize the installation of the connecting member 16 on the valve cover 1504.

[0033] Specifically, the valve cover 1504 and the connector 16 are quickly assembled through a connecting structure. During assembly, the connector 16 is inserted into the recess 15041 of the valve cover 1504 through a connecting column, and the two are fastened together by snaps and / or screws.

[0034] Further, if Figure 5-Figure 7 As shown, a connecting channel 21 is provided between the connecting member 16 and the valve cover 1504, and the valve core assembly 1503 includes a valve stem 15031 and a sealing member 15032. The sealing member 15032 is provided on one end of the valve stem 15031, and the other end of the valve stem 15031 is connected to the driving assembly. The sealing member 15032 is moved by the valve stem 15031, thereby sealing the connecting channel 21 or connecting the water outlet 1602, the connecting channel 21 and the drain outlet 1501.

[0035] Specifically, by opening or sealing the connecting channel 1603, when water supply is needed, the blocking member 15032 seals the connecting channel 1603, allowing water to flow into the user's waterway, preventing water from contacting the valve core assembly 1503, and avoiding water contamination; in the drainage state, the blocking member 15032 opens the connecting channel 1603 and discharges the residual water to the waste water box 17, preventing the residual water from being retained in the pipeline, thereby further improving the hygiene standards of the equipment.

[0036] Further, if Figure 5-Figure 7 As shown, the valve core assembly 1503 also includes a valve plate 15033 and an elastic member 15034. The valve plate 15033 is arranged on one end of the sealing member 15032. The elastic member 15034 is located between the valve plate 15033 and the driving assembly 1502. The sealing member 15032 seals the connecting channel 21 under the action of the elastic member 15034.

[0037] Specifically, the elastic member 15034 provides the necessary rebound force after the valve core assembly 1503 performs the switching action, so that the valve plate 15033 and the blocking member 15032 quickly return to their initial positions, ensuring that each action of the blocking member 15032 can be correctly reset. It should be pointed out that the initial position of the blocking member 15032 is to seal the connecting channel 21.

[0038] Further, if Figure 1 and Figure 2 As shown, a water pump 18 and a kettle body 2 for storing liquid are provided on the body 1. The water pump 18 is located below the kettle body 2. The water inlet end of the water pump 18 is connected to the kettle body 2. The water outlet end of the water pump 18 is connected to the water inlet 1601. A water outlet 101 is provided on the body 1. The water outlet 1602 is vertically connected to the water outlet 101. When the sealing member 15032 is in the open communication channel 21, the water between the water outlet 101 and the water outlet 1602 is discharged downward to the drain 1501 under the action of gravity.

[0039] Specifically, when the steady-state valve 15 is in the initial state, the blocking member 15032 seals the communication channel 1603 under the action of the elastic member 15034, so that the water inlet 1601 and the water outlet 1602 are connected. When the user presses the water extraction button or triggers the water extraction operation, the water pump 18 is started, and the water in the kettle body 2 is transported to the water inlet 1601 of the steady-state valve 15, and the water flows into the water outlet 101 through the water outlet 1602. The user can obtain the required drinking water from the water outlet 101. During this process, the steady-state valve 15 keeps the communication channel 1603 sealed to ensure that all water flows through the water outlet 1602. Water will not enter the valve core assembly 1503; after the user finishes taking water, the system controls the water pump 18 to stop working, and controls the sealing member 15032 of the steady-state valve 15 through the driving assembly 1502 to open the connecting channel 1603. Since the water outlet 1602 is vertically connected with the water outlet 101, after the water pump stops, the water between the water outlet 1602 and the water outlet 101 will naturally flow to the drain outlet 1501 under the action of gravity, and finally be discharged into the waste water box 17. This process ensures that the residual water in the water outlet 101 and the water supply channel will not be retained, thereby ensuring that the user obtains fresh water when taking water next time.

[0040] Further, if Figure 1-Figure 3 As shown, a circuit board 19 and a control panel 20 are provided on the machine body 1 . The circuit board 19 is electrically connected to the control panel 20 , and the water pump 18 and the steady-state valve 15 are electrically connected to the circuit board 19 .

[0041] Specifically, the control panel 20 is the main interactive interface between the user and the device. The user can operate through the buttons or touch screen on the control panel 20 to control the start and stop of the water pump 18 and the switching state of the steady-state valve 15; the user can select different operating modes through the control panel 20, such as water extraction, drainage or self-cleaning, etc. When the user presses the water extraction button, the control panel 20 sends a signal to the circuit board 19, and the circuit board 19 controls the water pump 18 to start and transport the water in the kettle body 2 to the water outlet 101 for the user to use; after the water extraction is completed, the user can select the drainage function, and the control panel 20 instructs the circuit board 19 to switch the state of the steady-state valve 15, open the connecting channel 1603, and discharge the residual water on the water outlet 101 into the waste water box 17; the whole process can be completed through simple operation of the control panel 20, and the user experience is more convenient.

[0042] Further, if Figure 1-Figure 3 As shown, a drawer-type waste water box 17 is provided on the machine body 1, and the drain port 1501 is connected to the waste water box 17.

[0043] Specifically, the waste water box 17 is located on the side of the body 1 and is designed in a drawer-type structure, which is convenient for users to take out and clean it regularly; in the drainage state, the blocking member 15032 opens the drainage path and discharges the residual water into the waste water box 17.

[0044] Further, if Figure 1-Figure 3 As shown, a bracket 102 for fixing the steady-state valve 15 is provided on the body 1 . The steady-state valve 15 is transversely fixed to the bracket 102 by screws and / or buckles. The bracket 102 is located above the wastewater box 17 .

[0045] Specifically, the fixing method of screws and / or buckles provides a solid support, so that the steady-state valve is not easily displaced or loosened during operation, and is easy to replace or repair.
