Detailed Implementation

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. In addition, it should be understood that the specific embodiments described herein are only for illustration and explanation of this application and are not intended to limit this application. In this application, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the device in actual use or operation, specifically the drawing directions in the accompanying drawings; while "inner" and "outer" refer to the outline of the device.

[0026] According to a first aspect of this application, a replenishment tank 10 is provided, suitable for an AEM hydrogen-oxygen generator. (See reference...) Figure 5 , Figure 5 The structure related to the hydrogen-oxygen generator 100 to which the replenishment tank 10 provided in the embodiments of this application is applicable. Exemplarily, as shown... Figure 5 As shown, the replenishment tank 10 is located inside the hydrogen-oxygen generator 100. One end of the replenishment tank 10 is connected to the electrolytic cell 30 to continuously supply liquid to the electrolytic cell 30, and the other end is connected to the liquid source 200 to introduce liquid into the replenishment tank 10.

[0027] The following describes in detail the fluid replenishment tank 10 of this application embodiment with reference to the accompanying drawings.

[0028] Reference Figures 1 to 5 The replenishment tank 10 includes a tank body 11, a first pipeline 12, and an electronic control valve 13. The tank body 11 has a liquid-containing cavity and is used to supply liquid to the electrolytic cell 30 of the hydrogen-oxygen generator 100. One end of the first pipeline 12 is connected to the tank body 11, and the other end is connected to a liquid source 200 to supply liquid to the liquid-containing cavity. The electronic control valve 13 is located on the first pipeline 12 and is used to control the opening / closing of the first pipeline 12 according to the liquid level in the liquid-containing cavity.

[0029] It is understandable that the liquid is the raw material for electrolysis.

[0030] The replenishment tank 10 is located inside the hydrogen-oxygen generator 100, and the liquid source 200 is located outside the hydrogen-oxygen generator 100. The first pipeline 12 is connected to the liquid source 200 to introduce liquid into the receiving cavity.

[0031] The liquid source 200 and the replenishment tank 10 can be located in the same workspace, allowing liquid to be supplied to the replenishment tank 10 from a nearby location. Alternatively, the liquid source 200 can be located away from the replenishment tank 10 to facilitate the storage of large quantities of liquid.

[0032] The electronic control valve 13 is used to control the opening or closing of the first pipeline 12 as needed. The electronic control valve 13 can be opened and closed by means of electromagnetic force or motor drive, thereby controlling the on / off state of the first pipeline 12. The electronic control valve 13 can adopt existing structures, which will not be described in detail here.

[0033] The electronic control valve 13 can control the opening or closing of the first pipeline 12 at regular intervals. The electronic control valve 13 can also control the opening or closing of the first pipeline 12 based on the liquid level data in the replenishment tank 10.

[0034] In this embodiment, by setting an electronic control valve 13 to control the opening and closing of the first pipeline 12 according to the liquid level in the containment cavity, the process of supplying liquid to the replenishment tank 10 is automated. As a result, the operation steps of replenishing liquid to the replenishment tank 10 are simplified, which helps to stably supply liquid to the replenishment tank 10 and improve the efficiency of hydrogen and oxygen production.

[0035] In some embodiments, the electronic control valve 13 is configured to open the first conduit 12 when the liquid level in the containment cavity is below a first threshold, and to close the first conduit 12 when the liquid level in the containment cavity is above a second threshold, wherein the second threshold is greater than the first threshold.

[0036] Liquid level refers to the horizontal height of the liquid within the container.

[0037] The first threshold is configured as the minimum liquid level required to maintain hydrogen and oxygen production, and the second threshold is configured as the maximum liquid level required to ensure stable operation of the hydrogen and oxygen generator 100.

[0038] The first pipeline 12 and the housing 11 can be connected by quick-connect fittings and PP hoses to reduce assembly difficulty.

[0039] Delayed manual replenishment of liquid to the replenishment tank 10 can easily lead to insufficient or no liquid in the tank. Insufficient liquid in the replenishment tank 10 can cause dry burning, damage to the electrolytic cell 30, and pose a safety hazard. Insufficient liquid in the replenishment tank 10 will affect the amount of hydrogen and oxygen produced. Delayed manual cessation of liquid supply can easily lead to excessive liquid in the replenishment tank 10, causing liquid overflow and affecting the stable operation of the hydrogen and oxygen generator 100.

[0040] In this embodiment, by configuring the electronic control valve 13 to open the first pipeline 12 when the liquid level in the receiving cavity is lower than a first threshold and to disconnect the first pipeline 12 when the liquid level in the receiving cavity is higher than a second threshold, the liquid level in the replenishment tank 10 is always kept within a suitable range. This helps to improve the control accuracy of the electronic control valve 13 and alleviate the problems of insufficient or excessive liquid caused by manual replenishment.

[0041] In some embodiments, the replenishment tank 10 further includes a first liquid level detector 14, which is signal-connected to the electronic control valve 13. The first liquid level detector 14 is used to detect whether the liquid level in the containment chamber is lower than a first threshold.

[0042] Specifically, the first liquid level detector 14 may include a first sensor, which may be a water immersion sensor. The water immersion sensor is set at the liquid level height corresponding to the first threshold and uses the principle of liquid conductivity for detection. When the probe of the first liquid level sensor protrudes above the liquid surface, an alarm signal is generated. The electronic control valve 13 controls the first pipeline 12 to open based on the alarm signal.

[0043] In some embodiments, the replenishment tank 10 further includes a second liquid level detector 15, which is signal-connected to the electronic control valve 13 and is used to detect whether the liquid level in the containment chamber is higher than a second threshold.

[0044] Specifically, the second liquid level detector 15 may include a second sensor, which may be a water immersion sensor. The water immersion sensor is set at the liquid level height corresponding to the second threshold and uses the principle of liquid conductivity for detection. When the probe of the second liquid level sensor is immersed in water, an alarm signal is generated, and the electronic control valve 13 controls the first pipeline 12 to disconnect based on the alarm signal.

[0045] In other embodiments, a liquid level detector can monitor the liquid level in real time and convert the liquid level data into an electrical signal, which is then transmitted to a control unit via wired or wireless means. The control unit receives the signals from the sensor and, based on these signals and preset parameter settings, determines whether the electronic control valve 13 needs to be opened or closed. When the electronic control valve 13 is open, the first pipeline 12 is connected; when the electronic control valve 13 is closed, the first pipeline 12 is disconnected.

[0046] The liquid level detector may include, but is not limited to, pressure liquid level sensors, float liquid level sensors, radar liquid level sensors, etc.

[0047] Reference Figures 1 to 4In some embodiments, the replenishment tank 10 further includes a second pipeline 16, which is connected to the outside of the tank body 11 and forms a communicating vessel structure with the tank body 11. The first liquid level detector 14 is disposed on the second pipeline 16.

[0048] In some embodiments, the second liquid level detector 15 is disposed on the second pipeline 16.

[0049] It is understood that the second pipe 16 is located outside the tank 11, and the first liquid level detector 14 and the second detector are also located outside the tank 11. The upper end of the second pipe 16 is higher than the second threshold, and the lower end of the second pipe 16 is lower than the first threshold.

[0050] The second pipeline 16 can be connected to the housing 11 via a quick-connect fitting and a PP hose.

[0051] Since the second pipe 16 and the box 11 form a communicating vessel structure, the liquid level in the box 11 is the same as the liquid level in the second pipe 16. The first liquid level detector 14 and the second detection sensor can detect the liquid level in the second pipe 16 to achieve the purpose of detecting the liquid level in the box 11.

[0052] In this embodiment of the application, by providing a second pipeline 16 inside the housing 11 and installing the first liquid level detector and the second liquid level detector 15 on the second pipeline 16, the first liquid level detector 14 can detect from outside the housing 11 whether the liquid inside the housing 11 is below the first threshold, and the second liquid level detector 15 can detect from outside the housing 11 whether the liquid inside the housing 11 is above the second threshold. Thus, the first liquid level detector 14 and the second liquid level detector 15 do not need to be assembled inside the housing 11, which helps to reduce the assembly difficulty of the first liquid level detector 14 and the second liquid level detector 15.

[0053] In some embodiments, at least a portion of the second conduit 16 is made of a transparent material. The transparent material allows operators to see the liquid level within the second conduit 16, facilitating intuitive observation of the liquid level and improving the accuracy of liquid level monitoring.

[0054] In some embodiments, the replenishment tank 10 further includes a level display. The level display is configured to display the level of liquid within the containment chamber.

[0055] In some embodiments, the second conduit 16 is a transparent conduit. It is understood that the second conduit 16 functions as a level indicator. This allows the level to be displayed without the need for a separate level indicator.

[0056] In some embodiments, the replenishment tank 10 further includes a first control valve 18, which is disposed at the bottom of the tank body 11 and is used to drain the liquid inside the tank body 11.

[0057] The first control valve 18 can be located outside the housing 11.

[0058] The first control valve 18 can be an electronic valve or a mechanical valve that can be manually opened and closed.

[0059] After prolonged use, impurities tend to settle at the bottom of the replenishment tank 10. In this embodiment, a first control valve 18 is provided at the bottom of the tank 11, allowing operators to open the valve to drain the liquid from the tank 11 and remove the settled impurities as needed.

[0060] Reference Figure 2 and Figure 5 In some embodiments, the replenishment tank 10 further includes a third pipeline 17 and a second control valve 19. One end of the third pipeline 17 is connected to the tank body 11, and the other end is used to connect to the flame arrester 40 of the hydrogen-oxygen generator 100, so that the liquid in the flame arrester 40 flows back to the receiving cavity. The second control valve 19 is disposed on the third pipeline 17 and is configured to control the on / off state of the third pipeline 17. It can be understood that the second control valve 19 can control the opening or closing of the third pipeline 17.

[0061] The third pipe 17 can be connected to the bottom of the housing 11 via a quick-connect fitting.

[0062] The second control valve 19 can be an electronic valve or a mechanical valve that can be manually opened and closed.

[0063] The flame arrester 40 is a flame-arresting component within the hydrogen-oxygen generator 100. During operation of the hydrogen-oxygen generator 100, if the mixing ratio of hydrogen and oxygen is improper or the gas supply fluctuates, the combustion reaction may propagate backward within the hydrogen-oxygen generator 100 or its pipelines, resulting in a backfire phenomenon. When the flame passes through the flame arrester 40, the metal or ceramic materials within the flame arrester 40 absorb the heat of the flame, rapidly reducing the flame temperature and thus preventing further flame propagation.

[0064] The internal temperature of the hydrogen-oxygen generator 100 is high. After the liquid in the electrolytic cell 30 evaporates, it partially liquefies with the flame arrester 40, resulting in liquid inside the flame arrester 40.

[0065] In this embodiment, by providing a third pipe 17 to connect the flame arrester 40, the liquid collected inside the flame arrester 40 can flow back to the receiving cavity, improving the utilization rate of the liquid and saving production costs. Furthermore, the return of the liquid collected in the flame arrester 40 to the receiving cavity helps dissipate heat from the flame arrester 40.

[0066] Reference Figure 1 and Figure 2In some embodiments, the replenishment tank 10 further includes a circulation pump 60, which is connected to the lower part of the tank body 11 via a quick-connect structure. The circulation pump 60 is used to deliver liquid to a separator (not shown) and then pump it to the electrolytic cell 30.

[0067] In some embodiments, the bottom of the replenishment tank 10 is further provided with a mounting plate 50 so that the replenishment tank 10 can be installed on the housing of the hydrogen-oxygen generator 100 or on a bracket connected to the housing.

[0068] Among them, the mounting plate 50 can be a sheet metal part.

[0069] This application embodiment provides a replenishment tank 10, which includes a tank body 11, a first pipe 12, a second pipe 16, a third pipe 17, an electronic control valve 13, a first control valve 18, a second control valve 19, a first liquid level detector 14, and a second liquid level detector 15. The tank body 11 has a receiving cavity. The first pipe 12 is located outside the tank body 11, with one end connected to the upper part of the tank body 11 and the other end connected to a liquid source 200. The second pipe 16 is located outside the tank body 11 and forms a communicating vessel structure with the tank body 11. The second pipe 16 and the first pipe 12 are located on different sides of the tank body 11. The second pipe 16 is made of transparent material. The first liquid level detector 14 and the second detector are disposed on the second pipe 16. The first liquid level detector 14 is signal-connected to the electronic control valve 13 and is used to detect whether the liquid level in the receiving cavity is lower than a first threshold. The second liquid level detector 15 is signal-connected to the electronic control valve 13 and is used to detect whether the liquid level in the containment chamber is higher than a second threshold. The electronic control valve 13 is configured to open the first pipeline 12 when the liquid level in the containment chamber is lower than a first threshold, and to close the first pipeline 12 when the liquid level in the containment chamber is higher than the second threshold, wherein the second threshold is greater than the first threshold. The first control valve 18 is located at the bottom of the housing 11 and is used to drain the liquid in the housing 11. One end of the third pipeline 17 is connected to the bottom of the housing 11, and the other end is used to connect to the flame arrester 40 of the hydrogen-oxygen generator 100, so that the liquid in the flame arrester flows back to the containment chamber. The second control valve 19 is located in the third pipeline 17 and is configured to control the opening / closing of the third pipeline 17.
