[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0028] Please see Figure 1 The first embodiment of this utility model provides a water dispenser, including a water inlet component 10, a power supply component 20, a water flow pipe 30, a water outlet component 40, and an electrolytic cell 50. The water inlet component 10 is connected to an external water source, and the electrolytic cell 50 is connected to the water inlet component 10 and the water outlet component 40 respectively through the water flow pipe 30. The power supply component 20 is electrically connected to the electrolytic cell 50.

[0029] The power supply component 20 is used to provide operating current to the electrolytic cell 50 and to adjust the magnitude of the operating current.

[0030] Specifically, the water inlet assembly 10 sends external water into the electrolytic cell 50 through the water flow pipe 30. After being powered on, the electrolytic cell 50 can electrolyze the water source (with a small amount of electrolyte added to enhance conductivity) into two types of water. Using the anode and cathode reactions, alkaline water is generated in the cathode area and weakly acidic water is generated in the anode area. The two are separated by the ion exchange membrane, and acidic water and alkaline water are output independently from the water outlet assembly 40.

[0031] The power supply component 20 can adjust the reaction rate of the anode and cathode of the electrolyzer 50 by regulating the operating current of the electrolyzer 50, thereby adjusting the alkalinity of the output water. For example, the higher the current, the more hydroxide ions are generated per second at the cathode, and the higher the alkalinity (pH value) of the water. In this way, drinking water with different alkalinity values ​​can be output at the water outlet component 40 by adjusting the operating current.

[0032] In one specific embodiment, the power supply component 20 can divide the operating current into three levels, corresponding to the output of drinking water with three different alkalinity values. Furthermore, even when the electrolysis cell 50 is not powered, it can directly output water that is neither alkaline nor acidic.

[0033] It is understandable that the electrolytic cell 50 can also output acidic water to the water outlet assembly 40 through the water flow pipe 30.

[0034] Furthermore, the power supply component 20 includes a power supply 21 and a current regulator 22. The power supply 21, the current regulator 22 and the electrolytic cell 50 form a series circuit to regulate the operating current of the electrolytic cell 50.

[0035] It is understandable that the magnitude of the current in the series circuit is adjusted by the current regulating element 22, thereby controlling the magnitude of the working current supplied to the electrolytic cell 50, so as to achieve the output of water with different alkalinity values ​​from the electrolytic cell.

[0036] Please see Figure 2 The current regulating component 22 includes a first main control switch K1, a second main control switch K2, a first branch switch S1, a second branch switch S2, a third branch switch S3, a first resistor R1, and a second resistor R2. The second main control switch K2 is connected to one end of the electrolytic cell 50 and the positive terminal of the power supply 21. The other end of the electrolytic cell 50 is connected to one end of the first branch switch S1, the first resistor R1, and the second resistor R2. The other ends of the first resistor R1 and the second resistor R2 are connected to one end of the second branch switch S2 and the second branch switch S3, respectively. The other ends of the first branch switch S1, the second branch switch S2, and the third branch switch S3 are all connected to one end of the first main control switch K1. The other end of the first main control switch K1 is connected to the negative terminal of the power supply 21. The resistance value of the first resistor R1 is less than that of the second resistor R2.

[0037] Specifically, the positive and negative terminals of power supply 21 form a current loop. The first main control switch K1 and the second main control switch K2 are connected in series in the current loop to control the on / off state of the entire current loop. Electrolytic cell 50 is also connected in series in the current loop. The first branch switch S1, the second branch switch S2, and the third branch switch S3 form parallel branches in the current loop. The first resistor R1 is connected in series in the branch of the second branch switch S2, and the second resistor R2 is connected in series in the branch of the third branch switch S3. Thus, by opening / closing the first branch switch S1, the second branch switch S2, and the third branch switch S3, the current in the current loop is adjusted, that is, the working current of electrolytic cell 50 is adjusted.

[0038] By forming parallel branches in the current loop, the magnitude of the operating current can be adjusted simply by opening and closing the switch.

[0039] To illustrate with a specific example: When the first main control switch K1 and the second main control switch K2 are open, the current loop is broken, the electrolytic cell 50 is not energized, and the water entering through the inlet component 10 flows directly through the electrolytic cell 50 and out through the outlet component 40, which outputs purified water. When the current loop is connected, the first branch switch S1 and the second branch switch S2 are open, and the third branch switch S3 is closed. The operating current of the electrolytic cell 50 is the first current value, and the outlet component 40 outputs water with a low alkalinity value. When the current loop is connected, the first branch switch S1 and the third branch switch S3 are open, and the second branch switch S2 is closed, the operating current of the electrolytic cell 50 is the second current value, and the outlet component 40 outputs water with a medium alkalinity value. When the current loop is connected, the first branch switch S1 is connected, and the second branch switch S2 and the third branch switch S3 are disconnected, the working current of the electrolytic cell 50 is the third current value. At this time, the water output component 40 outputs a high alkalinity water flow.

[0040] It is understandable that the first current value is less than the second current value, which is less than the third current value. The high, medium, and low alkalinity values ​​are relative high, medium, and low values ​​after comparing the alkalinity values ​​of the three water flows.

[0041] When the electrolytic cell 50 outputs water with different alkalinity values, it can also output water with different acidity values. By setting different water paths, corresponding water outlets and corresponding valves in the electrolytic cell 50, it can achieve the output of alkaline or acidic water. The structure of the electrolytic cell 50 is not limited here. In this embodiment, only the generation of acidic water at the third current value is considered.

[0042] It is understandable that, in addition to the circuits mentioned above, the current regulating component 22 can also be a variable circuit element in the current loop, such as a sliding rheostat or a thermal / photoresistor; it can be a semiconductor device, such as a transistor / field-effect transistor or a thyristor; it can also be a pulse width modulation, such as by rapidly switching on and off using a high-frequency switch (such as a transistor or MOSFET) to adjust the proportion of conduction time (proportion space), thereby changing the average current obtained by the load; or it can be a change in the circuit structure, etc., as long as the adjustment of the operating current of the electrolytic cell 50 can be achieved.

[0043] In a specific example, power supply 21 provides two DC power supplies: constant voltage 24V (3A) and constant current 3.5A (36V). The constant voltage 24V is used to power the various solenoid valves and self-priming pump 11 in the water flow pipeline 30, and the constant current 3.5A is used to power the dewatering tank 50. The current regulating component 22 is a baffle plate.

[0044] It should be noted that when the operating current is the third current, the output alkaline water also contains dissolved saturated hydrogen gas, and the output acidic water contains abundant oxygen.

[0045] Furthermore, the water inlet assembly 10 includes a self-priming pump 11 and a flow meter 12. The self-priming pump is connected to an external water source and to the water flow pipeline 30. The flow meter 12 is located at the output end of the self-priming pump 11.

[0046] It is understandable that flow meter 12 is a Hall effect flow meter, which is used to detect the flow rate of water.

[0047] In one specific embodiment, the self-priming pump 11 supplies water at a pressure of 2.5 kg or higher.

[0048] Furthermore, the electrolytic cell 50 has an electrolytic water inlet 51 and an electrolytic water outlet 52, and the water flow pipeline 30 includes an inlet valve 31 and an outlet valve 32. The inlet valve 31 is connected to the inlet assembly 10 and the electrolytic water inlet 51, and the outlet valve 32 is connected to the outlet assembly 40 and the electrolytic water outlet 52.

[0049] In one specific embodiment, the flow meter 12 is disposed between the self-priming pump 11 and the inlet valve 31.

[0050] It is understood that by setting the inlet valve 31 and the outlet valve 32, the water flow is controlled to enter and exit. That is, the inlet valve 31 controls whether the water flows from the inlet component 10 into the water flow pipe 30, and the outlet valve 32 controls whether the water flows from the water flow pipe 30 into the outlet component 40.

[0051] Furthermore, a first throttle valve 33 is provided between the electrolytic cell 50 and the water outlet assembly to throttle the water outlet speed of the electrolytic cell 50, so as to make the electrolysis more complete.

[0052] That is, a first throttle valve 33 is provided between the electrolysis outlet 52 and the water outlet assembly 40, and the first throttle valve 33 is connected to the electrolysis outlet 52 and the water outlet valve 32 respectively.

[0053] It is understandable that the first throttle valve 33 is used to control the water output and, under appropriate inlet water pressure, throttles the water output rate of the electrolytic cell 50 to ensure that there is appropriate water pressure in the electrolytic cell 50 so that electrolysis is complete.

[0054] Furthermore, a disinfection and sterilization component 34 is provided between the first throttle valve 33 and the water outlet assembly 40.

[0055] In one specific embodiment, the disinfection and sterilization component 34 is a UVC disinfection and sterilization device, used to disinfect and sterilize the water flowing out of the electrolysis cell 50 to ensure drinking safety.

[0056] Please see Figure 3 The first throttle valve 33 includes a housing 331, a fixing plate 332 and a capillary tube 333. The fixing plate 332 is disposed inside the housing 331 and closes the water flow channel of the first throttle valve 33. The capillary tube 333 is connected to the fixing plate 332 and passes through the fixing plate 332.

[0057] Specifically, by setting capillary tubes 333 with different inner diameters, the water flow rate can be controlled, which can throttle the speed at which water flows through the first throttle valve 33, thereby throttling the water outlet speed of the electrolytic cell 50.

[0058] In one specific embodiment, the capillary 333 is made of 304 stainless steel.

[0059] Furthermore, the water flow pipeline 30 also includes a flushing valve 35, which is connected to the electrolysis outlet 52.

[0060] It is understandable that the flushing valve 35 is used to clean the interior of the electrolytic cell 50 before use.

[0061] To illustrate with a specific example, when rinsing the interior of the electrolytic cell 50 is required, the inlet valve 31 and the rinsing valve 35 are opened, and the outlet valve 32 is closed. At this time, water flows from the inlet valve 31 through the electrolysis inlet 51 into the electrolytic cell 50 and flows out from the electrolysis outlet 52. Because the outlet valve 32 is closed, the water cannot pass through the outlet valve 32 into the outlet assembly 40 and can only flow out from the rinsing valve 35. However, when electrolysis is required, the inlet valve 31 and the outlet valve 32 are opened, and the rinsing valve 35 is closed. At this time, the water flows out from the electrolysis outlet 52, passes through the first throttle valve 33, the disinfection and sterilization component 34, and the outlet valve 32 before entering the outlet assembly 40, thus achieving water output.

[0062] Furthermore, the water flow pipeline 30 also includes a wastewater discharge valve 36, and the electrolytic cell 50 also has a wastewater discharge outlet 53. The wastewater discharge valve 36 is connected to the wastewater discharge outlet 53 and the flushing valve 35 respectively.

[0063] It is understandable that the wastewater discharge valve 36 is used to discharge the wastewater generated during the electrolysis process of the electrolytic cell 50 and the water flow used for rinsing in the flushing valve 35.

[0064] Furthermore, a second throttle valve 37 is provided between the wastewater outlet 53 and the wastewater discharge valve 36, and the second throttle valve 37 is connected to the wastewater outlet 53 and the wastewater discharge valve 36 respectively.

[0065] It is understandable that the second throttle valve 37 is used to control the wastewater discharge.

[0066] In one specific embodiment, the second throttle valve 37 has the same structure as the first throttle valve 33.

[0067] Furthermore, the water outlet assembly 40 includes a water outlet component 41 and a water receiving tray 42. The water outlet component 41 is connected to the water outlet valve 32, and the water receiving tray 42 is located below the water outlet component 41.

[0068] It is understandable that the drip tray 42 can be used to place water cups.

[0069] Furthermore, the water dispenser also includes a control panel and a main control board. The main control board is electrically connected to the control panel and the current regulator 22, respectively, and is used to control the current regulator 22 to adjust the working current of the electrolytic cell 50 according to the input of the control panel.

[0070] In one specific embodiment, there are five settings: purified water, alkaline water (1), alkaline water (2), alkaline water (3) and acidic water, wherein alkaline water (1), alkaline water (2) and alkaline water (3) correspond to water with high, medium and low alkalinity values, respectively.

[0071] Please see Figure 4 The second embodiment of this utility model provides a water dispenser, wherein there are two power supply components 20 and two electrolysis cells 50. The two power supply components 20 are electrically connected to the two electrolysis cells 50 respectively to adjust the working current of the two electrolysis cells 50 respectively. The two electrolysis cells 50 are connected to the water inlet component 10 and the water outlet component 40 respectively through the water flow pipe 30.

[0072] Specifically, the two power supply components 20 supply power to the two electrolytic cells 50 respectively. The electrolytic cells 50 are connected in parallel before water discharge so that the two electrolytic cells 50 can work simultaneously, which can increase the water discharge efficiency.

[0073] Furthermore, a first throttle valve 33 is installed at the electrolysis outlet 52 of both electrolytic cells 50, and a second throttle valve 37 is installed between the wastewater outlet 53 and the wastewater discharge valve 36.

[0074] Furthermore, there are two main control boards. The two main control boards are electrically connected to the current regulators 22 of the two power supply components 20, and both are electrically connected to the main control panel. The input of the control panel can be transmitted to the two main control boards at the same time. The two main control boards then control the two current regulators 22 respectively to adjust the working current of the two electrolytic cells 50.

[0075] The working principle of the water dispenser provided in this embodiment is as follows: After selecting the gear on the control panel, the water is first rinsed. The inlet valve 31 and the rinsing valve 35 are opened, and the outlet valve 32 is closed. The self-priming pump 11 works to draw in external water. The water flows through the inlet valve 31 and the electrolysis inlet 51 into the electrolysis tank 50, and then enters the rinsing valve 35 from the electrolysis outlet 52. Finally, the water flows out from the rinsing valve 35 into the wastewater discharge valve 36. When the flow meter 12 senses that the water flow is normal, the rinsing process is completed, the rinsing valve 35 is closed, and the outlet valve is opened.

[0076] Next, depending on the selected control panel setting, different water flows will be output:

[0077] When the water purification setting on the control panel is selected, the current regulator 22 blocks the working current of the electrolysis cell 50, and the water outlet assembly 40 outputs water normally. When the alkaline water setting on the control panel is selected, the current regulator 22 controls the magnitude of the working current of the electrolysis cell 50 according to different alkalinity settings, and the water outlet assembly 40 outputs alkaline water with different alkalinity values. When the acidic water setting on the control panel is selected, the water outlet assembly 40 outputs acidic water.

[0078] Compared with the prior art, the water dispenser provided by this utility model provides different working currents to the electrolytic cell through the power supply component, thereby adjusting the reaction speed of the anode and cathode of the electrolytic cell, and thus forming water flows with different alkalinity / acidity values ​​according to the selected setting.

[0079] The electrolytic cell is connected in series with a current regulating element, forming parallel branches with different resistance values. The working current can be adjusted by simply opening and closing the switch, thereby adjusting the working current of the electrolytic cell.

[0080] Through the structural design of the first throttle valve, the water flow rate can be controlled by setting capillary tubes with different inner diameters. The speed at which water flows through the first throttle valve can be throttled, thereby throttling the water outlet speed of the electrolytic cell to ensure that there is appropriate water pressure in the electrolytic cell, so that electrolysis can be complete.

[0081] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
